REFINING

In quest for making the finest grade of steel, refining procedure is brought out through LRF (spoon refining heater). The liquid material is refined in a way exceptional to MISIL through compound expansion and nitrogen cleansing procedure. Encourage amalgams, for example, Manganese, Nickel, Chrome, Vanadium, Molybdenum and so on are added to make exceptional steel, spring steel, auto thought process steel, stainless steel and low compound steel. The two components that can be for the most part in charge of influencing the qualities and properties of the steel, carbon and sulfur, are controlled moreover by LECO ignition mechanical assembly. The concoction organization of the steel is investigated by outflow spectrometry and finish change of the temperature and compound examination is completed in the spoon heater, together with the aggregate end of pollutions (non-metallic considerations and sulfur) by infusion of argon, through the base of the scoop.

A secondary steelmaking process is carried out during which oxygen and argon are blown into the molten steel. This method enables carbon to be removed without oxidising chromium for refining stainless steel. Molten metal is stirred and homogenized to achieve the perfect level of alloying. At Shalimar Steel special stainless steel grades are made through AOD process. The only plant in Pakistan capable of manufacturing 60,000 tons per annum of stainless steel billets in conformance with 200, 300 and 400 series, through AOD (Argon Oxygen Decarburizer) converter having capacity of 18 tons per heat.,

Shalimar Steel range of casting facilities provides the optimum metallurgical process”> route for demanding steel types. Billet, the raw material of constructional steel is produced in appropriate quantities for hot and thermodynamic rolling during continuous casting. Highly specialized three strands continuous caster engineered and supplied by Concast is used by Shalimar Steel for the production of 80 x 80 mm, 100 x 100 mm, 130 x 130 mm and 150 x 150 mm billets of steel in a highly synergized manner. The liquid steel is discharged into a distributor unit. This unit has several holes at the bottom through which the liquid steel can flow into various casting lines or molds where the solidification of the steel takes place and semi-products (billets) are obtained. Later a cooling system is applied, first by the way of cold water jets and then by air. The billet is cut to the desired lengths using blowtorches which move with the billet during the cut.
