The DRI plant is designed to produce 150000 tonnes of sponge iron per annum. Currently, the firm has ~500Industry.Guru: Iron making processesSL/RN is the most widely accepted coal based DR process. It was jointly developed by Stelco, Lurgi Chemie, Republic Steel Company and National Lead Corporation in 1964. In this process, the materials charged into the kiln gravitate towards the discharge end during which they are progressively heated to the temperature of reduction of around 1000 - 1100 O C.Energy survey of the coal based sponge iron industry - .1/9/2015· The actual process of the coal based sponge iron production is based on SL/RN process (jointly developed by the Steel Company of Canada, Lurgi Chemie, Republic Steel Company and National Lead Corporation in 1964), which works on direct reduction of ore.การบริโภควัตถุดิบในการถลุงเหล็ก 1 ตัน .การบริโภคว ตถ ด บในการถล งเหล ก 1 ต น ด วยเทคโนโลย SL/RN ว ตถ ด บสำหร บกระบวนการผล ต SL/RN ปร มาณ Iron Ore Fe Fe 2 O 3 O gangue 68.5 % 98.0 % 29.0 % 2.0 % Coal C Ash 90.0 % 10.0 % DRI .
