The Differences Between Extruded Aluminum Bar And Cold Finished Aluminum Bar

by kalpataru | Aug 24, 2022 | Blog

What is Extruded Aluminum?

Extrusion is the technique of driving a material through a die to create a cross-sectional bar, whether it be aluminium or another material. Despite having a number of steps, the method is rather straightforward. The final exterior dimension of the extruded bar must first be produced by a manufacturer or designer using a die.

The finished die is put into an extrusion press where a billet of the desired alloy of aluminium is heated to the necessary temperature, making it malleable. The press then pushes the aluminium through the die, causing a lineal length of regularly formed aluminium to emerge from the other side.

The extruded piece is tension relieved and then cut to the required length after cooling. Now that the metal has undergone post-production processes, it can be heat treated. Less pressure is needed to push the metal through the die since the process occurs at a high temperature, up to 75% of the melting point of aluminium. This indicates that it is quicker than cold forming techniques.

What Is Cold-Finished Aluminum?

Since aluminium is simpler to form at higher temperatures, extrusion is frequently done there as opposed to cold finishing, which is done at ambient temperature. Extremely tight tolerances for the outer diameter are produced by cold finishing. The most typical kind of cold finishing is drawing.

What is the Difference between Extruded and Cold Finished Aluminum?

Standard aluminium extrusions have the main benefit of being significantly simpler to work with at higher temperatures. An extruded bar often costs less than a cold finished product since this corresponds to faster production rates. Faster production leads to shorter lead times to market.

The tighter dimensional tolerances produced by cold finished production are helpful for using the close-fitting collets present in modern high-speed precision CNC machining machines. Additionally, it enhances the material’s mechanical and physical qualities, boosting machinability and resulting in smaller, quicker-elimination chips during milling.

Extruded and Cold Finished Aluminum are Used in What Applications?

Although extruded aluminium is frequently used in many different applications, it is not appropriate for all of them. The use of the cold finished product as a raw material may result from any requirement for improved properties. Cold polished bar is often used in automotive applications as well as aerospace and defense products that need high strength. In cold finished applications, alloys including 2011, 2024, 6061, and 7075 are employed. Extrusions frequently use the aluminium alloys 1100, 3003, 6061, 6063, and 6101. Probably the most popular is 6061, which is prized for its advantageous characteristics.

Different Type of Steel Reinforcement Bars : There are different kinds of steel bars that can be used for building. You should know which one you should choose and why.

Some of the Best Uses of Inconel 600 Round Bars : INCONEL (nickel-chromium-iron) alloy 600 Round bars (UNS N06600/W.Nr. 2.4816) is a technological material that is heat and corrosion resistant. Excellent mechanical properties of the alloy combine high strength with ease of production.

Different Type of Steel Reinforcement Bars

by kalpataru | Aug 24, 2022 | Blog

Introduction

A number of steel bar types are used in concrete buildings. The endurance of the concrete construction is ensured by the use of reinforced steel bars.

Concrete is made with 5 different kinds of steel reinforcement bars.

Hot Rolled Deformed Bars

Cold Rolled Steel Bars

Mild Steel Bars

Twisted Steel Bars

Welded Steel Wire

Hot Rolled Deformed Bars

TMT Bars, which stand for Thermo mechanically treated bars, are another name for hot-rolled deformed bars. Because they have high tensile strength, TMT Bars are often used in RCC (Reinforced Concrete Structure). The ribs on TMT Bars make it possible for cement concrete to stick together better. The best TMT Bars have a tensile strength of 64,000 psi (PSI – Strength of Concrete is measured in pounds per square inch).

Cold Rolled Steel Bars

Even though cold-rolled steel bars are made at room temperature, they look like hot-rolled bars. These bars are made of weak materials and are easy to bend. Cold-rolled bars are almost no longer on the market, but they are still used in some building projects that don’t require a lot of tolerance. It can be stretched up to 60,000 psi.

Mild Steel Bars

This bar is round and has a smooth, flat surface. Mild steel bars are used to make beams and slabs out of RCC. There is a tensile strength of up to 40,000 psi. Mild steel bars are used in small projects with limited funds because they don’t stick well to concrete and aren’t very good.

Twisted Steel Bars

Twisted steel bars are also called “prestressing tendons.” Almost seven different wires have been woven together to make this string. Twisted steel bars have a high tensile strength of 270,000 psi. Most of the time, these are used on scaffold braces to make reinforced cement concrete stronger. It makes sense because of how well it holds together.

Welded Steel Wire

Steel wires are joined together to make weld mesh. A medium amount of tensile strength is made. These are used for fencing, dividing rooms, etc. It is often used in certain parts of buildings because it is easier to find in different diameters and is stronger than a mild steel bar.

It is very important to know that thermomechanically treated (TMT) bars are often used because they have high tensile strength. TMT Bars are strong and also have the right amount of flexibility. Because of this, it offers the best protection possible during any natural disaster, such as an earthquake, flood, etc. TMT Bars have less carbon than other types of steel, which makes them very resistant to corrosion and less likely to wear down over time.

IS Standards say that the Fe 500d grade of TMT Bar is the best mix of strength and flexibility. Because of this, it is highly recommended for building projects.

Govt directs steel industry to draw a time-bound action plan to lower CO2 emissions

by kalpataru | Jul 5, 2022 | Blog

In order to comply with the government’s COP26 commitments, the Ministry of Steel has requested the stakeholders to develop a time-bound action plan to cut emissions in the steel industry. A government report states that whereas the iron and steel sector generally generates 8 percent of the world’s yearly carbon dioxide (CO2) emissions, it makes up 12 percent of the total CO2 emissions in India. The COP26 climate change summit’s accords require the Indian steel industry to considerably decrease its emissions.

Prime Minister Narendra Modi said at the COP26 global climate summit in November 2021 that India will reach its goal of having net zero emissions by the year 2070.

In a recent meeting, Steel Minister Ram Chandra Prasad Singh “urged the stakeholders to develop a time-bound action plan and work together to reduce emissions from the steel industry in line with the commitments made by the Government at COP26.”

In addition, the current situation, the next steps for promoting the switch to green steel, the various strategies and technologies that the steel industry can use to produce green steel, and the levels of technological readiness were discussed.

At the meeting, participants also discussed using green hydrogen to produce iron and carbon capture, utilization, and storage (CCUS) technologies to reduce emissions.

“Reputable academic institutions, research laboratories, and steel companies have submitted joint collaborative R&D project proposals for the development of new alternative processes and technologies to address the sector’s challenges…(and) The ministry will provide financial assistance under the R&D Scheme for the Financial Year 2022-23.

How is India planning to decarbonise the steel industry

by kalpataru | Jul 5, 2022 | Blog

Introduction

As one of the most significant materials for engineering and construction, steel is used in many aspects of our life. Steel is one of the most important components of modern society. The steel sector is currently one of the three industries that produce the most carbon dioxide. Therefore, steel businesses across the globe face an increasing decarbonization challenge to decrease their environmental and economic carbon footprint.

Currently, India is the world’s second-largest steel producer. India plans to treble its steel production by 2030, according to its National Steel Policy from 2017. Multiple analyses indicate that by 2050, the amount of steel utilized could increase by a factor of several. In order to meet expanding domestic and international demand, India’s steel production will significantly increase during the next few decades.

The majority of carbon emissions from steel factories may be readily extracted from their process- and off-gas. Thus, they are suitable candidates for carbon capture. This collected carbon can be sold back into the market, allowing manufacturers to maintain low costs while making significant progress toward global net-zero targets, or it can be stored for the long term. Captured CO2 from steel mills can be used as a raw material. For instance, it can be used with water and steel slag to produce construction materials. Tata Steel will establish India’s first carbon capture plant for blast furnaces in 2021. This facility will catch and reuse 5 tonnes of CO2 per day.

Use of Syngas

Syngas is typically produced by converting coal to gas, and their primary usage is to generate power. Using the syngas may be more efficient than directly burning the original fuel. Syngas can be utilized to produce an effective reducing gas that can be used to produce DRI. This method is utilized by the JSPL steel factory located in Angul, Odisha.

Use of Green Hydrogen

Hydrogen-based green steel production can make India less reliant on coal imports and more self-reliant. Investing in blast furnaces now will ensure that imported coal will be required until at least the middle of the century, if not longer. By replacing coal with hydrogen produced from renewable energy (dubbed “Green Hydrogen”), the majority of carbon could be eliminated from the industrial sector. If coal were replaced with hydrogen at the current price, steel prices would increase. This disparity is anticipated to narrow over the next few years, and it may perhaps disappear by 2030. On the one hand, carbon and carbon-emission pricing could increase the cost of utilizing coal, while on the other hand, the costs of renewable electricity, hydrogen, and steel production using hydrogen-based processes will decline. With Reliance and Adani entering the green hydrogen industry, India might become a leader in the production of green steel.

Use of Solar Power

To achieve the temperatures required for conventional steel production, a great deal of fossil fuel energy is employed. In India’s major steel-producing states, such as Odisha and Chhattisgarh, where there is abundant sunlight, solar energy can replace fossil fuels. Currently, solar electricity is the cheapest form of energy in India.

Through Adopting Energy Efficiency Measures

The steel business is subject to global competition, therefore producing steel using less energy can be a competitive benefit in addition to reducing energy use. Process industries can save expenses by utilizing energy more efficiently, and energy-saving solutions can be advantageous for a company. Utilizing more efficient technology, recovering energy throughout the manufacturing process, enhancing the efficiency of energy conversion, and ensuring that operational methods are as efficient as possible are ways to improve energy efficiency.

Through Recycling Steel Scrap

Reusing steel reduces the amount of ore that must be extracted. Additionally, it conserves energy and reduces greenhouse gas emissions. Steel can be recycled as often as necessary without losing its useful properties. This transforms a resource that cannot be utilized repeatedly into one that can. Recycling steel uses around half the energy required to produce new steel, resulting in fewer carbon emissions.

All of the above must be included in India’s carbon emission reduction plan. The PHD Chamber of Commerce and Industry is committed to assisting stakeholders and the Central and State Governments in their efforts to decarbonize business and industry. Minerals & Metals Committee and Power, Renewable & Alternate Energy Committee of PHDCCI have been working to prioritize policy reforms and promote sustainable development goals in order to achieve the ambitious decarbonization & RE target and assist the government in constructing an Atmanirbhar & Green Bharat.
