MS (Mild Steel) billets play a fundamental role in the steel industry. With reinforcement and flat stems with angles and structural steel products, MS billets are the semi-final form, allowing for more rotation and variation

But What Is the Process Behind Creating These Billets?

In this blog, we walk you through the essential steps of the MS billet manufacturing process — from raw material selection to final casting.

1. Choose to Go Out with Raw Materials and Waste

The first steps include the collection of soft steel losses, sponge iron, or direct iron repair (DRI). These raw materials are carefully categorized to eliminate impurities such as dust, rust, and non-metallic components. The goal is to maintain a uniform chemical composition of the final part. 

2. Make It in an Induction Oven or Electric Arc Oven

The sorted materials are fused at high temperatures (approximately 1600°C) in an electric arc oven (EAF) or induction oven. At this stage, alloy elements such as carbon, manganese, silicon, and other materials are included according to the required class of the room.

This step is essential as the quality of the fusion process directly affects the chemical and mechanical properties of the part.

3. Purification

After fusion, the liquid metal is transferred to the converted furnace (LRF) to adjust the composition and eliminate remaining impurities. Added dougi visor and flow to provide a clean, homogenous mixture. This operation is guaranteed:

• Highest carbon level regulations

• Retracting nonmetal inclusions

• Improved room uniformity

4. Continuous Casting Process (CCM)

The refined merged steel is then sent to a continuous molding machine (CCM), where it is hardened to dimensions of 100x100mm, 125x125mm or 160x160mm. Once the steel is cooled, it becomes a solid formulation of MS with a constant granular bone structure and surface decoration. 

Continuous casting boosts efficiency, reduces waste, and permits extended billet lengths of 6 meters or more.

5. Cutting & Surface Inspection

After casting, the billets are cut into specified lengths using automated flame or hydraulic cutting machines. 

Each billet is subjected to:

• Visual examination for cracks, blowholes, or irregularities

• Dimensional assessment to confirm precision

• Ultrasonic or chemical analysis (in premium applications)

6. Cooling, Storage & Dispatch

The billets cool on runout tables and are stored in a regulated environment. According to orders, they are:

• Marked with heat numbers

• Prepared for shipment

• Sent to rolling mills for transformation into TMT bars, angles, channels, flats, and various other steel profiles.

High-Quality MS billets Ensure:

• Sequences during rolling

• Increased life expectancy for tools during treatment

• More powerful products for construction, infrastructure and manufacturing
