Understanding the Manufacturing Process of TMT Bars: How Saluja Gold Ensures Quality Steel

When it comes to building strong and safe structures, the materials you choose are crucial. Among the most important materials in construction today are TMT (Thermo-Mechanically Treated) bars. They are the backbone of modern buildings, bridges, and infrastructure projects. But what sets Saluja Gold TMT bars apart from the rest? It’s all about their manufacturing process. Let’s dive into how Saluja Gold ensures they deliver steel that’s both high-quality and reliable, starting from the raw materials to the final TMT bars.

The TMT Bar Manufacturing Process at Saluja Gold

Saluja Gold has created a precise manufacturing process that guarantees strength, flexibility, and durability. Here’s how they do it:

1. Sponge Iron Production: Laying the Foundation at the DRI Plant

The journey begins at Saluja Gold’s Direct Reduced Iron (DRI) Plant, where high-quality iron ore turns into sponge iron. This crucial step ensures a strong, pure, and consistent base for steel production.

2. Steel Making and Billet Casting: Turning Iron into Steel

Next, Saluja Gold feeds the sponge iron into the Steel Melting Shop (SMS). In induction furnaces, the company melts the iron along with scrap steel to create molten steel. They then pour this steel into molds, which solidify into billets—long, rectangular blocks. These billets serve as the foundation for the TMT bars.

3. Hot Charging: A Smart Way to Save Energy

Saluja Gold uses hot charging, a smart technique where they send freshly cast billets to the rolling mill while still hot. This approach reduces energy consumption and preserves the steel’s quality by eliminating the need for reheating.

4. Hot Rolling: Shaping the Steel

The hot billets enter the rolling mill, where a series of rollers shape them into the desired size and length. During this process, the steel’s internal grain structure refines, which strengthens the bars further.

5. Quenching: Rapid Cooling for Maximum Strength

After the rolling process, Saluja Gold quickly cools the bars in the quenching process. This rapid cooling hardens the outer layer of the bars, creating a martensitic surface that gives them excellent surface strength. The core remains ductile, which allows the bars to bend without breaking.

6. Self-Tempering: Striking the Right Balance

Following quenching, the bars go through self-tempering, where heat from the core transfers to the outer layer. This step tempers the outer surface, improving the bar’s flexibility and toughness while maintaining its strength.

7. Atmospheric Cooling: Ensuring Uniform Strength

The bars then undergo atmospheric cooling, which ensures that the cooling process remains consistent. This step enhances the uniformity of the microstructure, boosting the bendability and weldability of the TMT bars.

8. Quality Control: Rigorous Testing at Every Stage

Saluja Gold has built rigorous quality control at every stage of production. From the raw materials to the final TMT bars, they test for strength, elongation, ductility, and chemical composition. These tests ensure that the bars meet or exceed industry standards like IS 1786.
