Tufcon XT | What We Do

The initial stage involves the extraction and preparation of raw materials:

The raw materials are fed into a blast furnace where a chemical reaction occurs, producing molten iron:

Charging: Iron ore, coke, and limestone are charged into the furnace.
Heating: The furnace is heated to a high temperature, melting the iron ore.
Reduction: Coke acts as a reducing agent, converting iron ore into molten iron.
Slag Formation: Limestone binds with impurities to form slag, which is removed.

The molten iron is then transferred to a ladle for further processing:

Desulfurization: Impurities like sulfur are removed using desulfurizing agents.
Alloying: Elements like carbon, manganese, and silicon are added to achieve the desired chemical composition.

The refined molten steel from the ladle is then poured into a continuous casting machine:

Tundish: Acts as a reservoir and controls the flow of molten steel.
Mould: The molten steel is poured into a water-cooled mould where it solidifies.
Cooling: The partially solidified steel is rapidly cooled using water sprays.
Cutting: The solidified steel is cut into desired lengths (billets).

The billets are transported to the rolling mill via a conveyor belt:

Transportation: Billets are moved on conveyor belts to the heat maintenance furnace.
Temperature Maintenance: Ensures billets remain at the required temperature for rolling.

The billets are heated and rolled into TMT bars in the rolling mill:

Roughing: Billets are passed through roughing stands to reduce their cross-section.
Intermediate Rolling: The billets are further rolled to intermediate sizes.
Finishing: Final shaping and sizing of TMT bars.

The hot-rolled bars pass through the Thermax box for quenching and self-tempering:

Quenching: High-pressure water jets rapidly cool the outer surface of the bars, forming a hardened surface layer (martensite).
Self-Tempering: The core remains hot, allowing heat to flow from the core to the surface, tempering the outer layer and giving the bars a tough, ductile core with a hard surface.

The quenched and tempered bars are transferred to a cooling bed:

The finished TMT bars are then transported to the stock yard:

Cooling Bed: The bars are placed on a cooling bed to ensure uniform cooling.
Inspection: The bars are inspected for quality and compliance with standards.
Bundling: Bars are bundled and tagged for identification.
Storage: Bundles are stored in the stock yard, ready for dispatch.
