Sponge iron manufacturing is highly sensitive to raw material characteristics that would help obtain the rated capacity and the desired product quality. To ascertain the suitability of our raw materials in a rotary kiln, Company has established a modern quality assurance facility that is responsible for conducting various tests in respect of the chemical and physical properties of our raw materials.
The plant being in the proximity of country iron ore sources, the entire iron ore is sourced from Tata Steel’s iron ore mines. In cases of exigency, there are several othere iron ore mines in the vicinity which supplies quality iron ore at competitive prices.
To enhance productivity at an optimal cost, improve product quality and kiln campaign life, company sources its majority requirement from South Africa, besides sourcing a specified quality from Eastern India.
Dolomite acts as a de-sulphuriser to remove sulphur from the feed mix during the reduction process. Control of sulphur content is an essential pre-requisite for the manufacture of good quality steel. The entire requirement of dolomite from the dolomite quarries in Bhutan and Chattisgarh.
