Presently, the Rolling Mill Division consists of Light & Medium Merchant Mill (LMMM), Wire Rod Mill (WRM) and Medium Merchant & Structural Mill (MMSM). The blooms of sizes 320 X 250 mm, 250 X 250 mm and billets of size 125X125 mm are re-heated in reheating furnaces and rolled in LMMM, MMSM and WRM to produce Rounds & Rebars of sizes from 16 to 36 mm, Rounds 40 to 80 mm, Squares 65 to 90 mm, Angles ISA 75 to 100 mm, Beams ISMB 125 to 175 mm, Channels ISMC 100 to 200 mm and Round & Rebar coils of sizes from 5.5 mm to 14 mm. For rolling of these products, work Rolls of different sizes and various materials like Alloy Forged Steel, Alloy Cast steel and Spheroidal Graphite Cast Iron with hardness range of 40 SHC to 75 SHC are being used. At present, an approx. weight of 1200 tons of ACS&SGCI work rolls per annum is being procured and the requirement is likely to increase with the commissioning of expansion mills in the coming years. In order to broaden the supplier-base, Expression of Interest (EOI) is being invited from reputed rolling mill work roll manufactures who are interested in supplying the proposed 14 types of ACS/SGCI work rolls as per Technical Specifications (ANNEXURE - II )and special instructions enclosed at ANNEXURE - I to RINL. - EXECUTIVE DIRECTOR ( MM ) 2
