Process

CHARGING RAW MATERIAL

In the yard, Mild steel scrap is accumulated and segregated based on their grades. Later they are transferred from the yard to the furnace as per the requirement. MS scrap are carried by a Grab/Magnet fitted to a Electric Overhead Traveling (EOT) crane and charged into the induction furnace.

INDUCTION FURNACE

Induction Furnace melts various grades of scrap and sponge Iron at 1650° C to convert them into liquid metal. During the entire process of melting, impurities are taped off and chemical composition is checked regularly in the in-house laboratory to achieve the right quality. Once the required chemical composition is achieved the molten metal is unloaded into the Ladle.

LADLE

The Ladle is filled with hot liquid metal which is handled by EOT crane and transported to continuous casting machine . Later ladle is moved to the continuous casting machine and placed over a tundish car.

CONTINUOUS CASTING

Slide gate assembly at the bottom of the Ladle is opened hydraulically so that the molten metal flows into the Tundish. The nozzle provided at the bottom of Tundish guides the molten metal to flow into mould tube. Oscillation table oscillates the mould tube to avoid creation of air pockets and void area inside the mould tube. Apron Assembly guides the Billet which is casted inside the mould tube, to come out through the withdraw unit. The Billet is then transported to the rolling mill through roller conveyors.

HOT CHARGING

Casted Billets are cut manually to the right size and they are fed directly into the rolling mill as hot billet. Hot billets are maintained at right temperature and size as they travel through the platform.

ROLLING

Billets are processed in roughing mill and intermediate mill which is located between the rolling mill and roughing mill to produce them in required diameter and length of TMT Bars. Repeater supports as guide to the billets into respective Mills.

COOLING BED

The Hot TMT bars are manually handled and placed on the cooling bed for atmospheric air cooling. The TMT Bars are then shifted to the Roller conveyor for final cutting to the desired length of 40’. End bits are collected after cutting is stored for recycling.

INSPECTION & PACKING

TMT Bars are manually placed on the Bending Machine. Later the Bent TMT Bars are tied with G.I. Wire along with an identification tag. Finally, the TMT Bars are stacked in the stock yard.
