BILLET

The Billet plant installed in 2010 is a ‘State-of-The-Art’ Production facility unit.

Shattaf Steel Manufactures Billets with Cross Section range of 100 x 100mm, 125 x 125mm & 130 x 130mm in Various Length as per the customer requirements. The Plant also produces billets in a wide range of chemical compositions to satisfy the customer’s requirements.

Our Products confirm the specification of BS 4449 :1997, BS 4449 :2005,ASTM A615 & KWS GSO ISO 6935-2.

The Billet Plant has capacity to produce 100,000 Mt Per Year.

Manufacturing Process

Step Process Description
1 Charging steel scrap Shattaf Steel is determined for the stable supply and management of steel scrap and carrying out strict inspections throughout the entire process from sourcing to charging into the furnace in order to generate high-quality steel products.
2 Melting Steel An Induction furnace uses electricity to heat steel scrap, convert steel scrap in to molten metal and removes impurities to generate steel during this process. The induction furnace maintains the temperature and adjusts the composition of five chemical properties of steel including C, Mn, Si, P and S in accordance with the related specifications.
3 Continues Casting This is a process of making the refined steel into billets. Throughout the continuous casting, the steel that has so far remained liquid is solidified into a shape. We improve the stability and productivity of the subsequent continuous casting process by maintaining the molten steel temperature at between 1,550 and 1,600 °C.
4 Transfer / Storage Billets made in the continuous casting process are fed into the Rolling mill stand through conveyer table called hot direct rolling or stored in Billet storage area.
