Abstract:
The Ternium Brasil Coke Plant is a Heat Recovery type and has a nominal production capacity of 1.8 million tons per year to supply the blast furnaces meeting the quality parameters established for the production of Pig Iron. The coal blend is responsible for approximately 37% of steel cost, and therefore studies are always sought to optimize the blend by minimizing losses. The project for consumption of coal, which comes from cleaning the rolling tracks of the Coke Plant and raw materials yard areas, aims to align cost reduction in coke production without loss of delivery quality to industrial scale blast furnaces. Chemical and physical analyses were carried out through the composition of several batches and, according to the results obtained, they were released for use on an industrial scale showing good performance in the Ternium Coqueria Plant. The generation of this carbonaceous material is 15 thousand tons per year. No significant changes in coke quality were observed during testing and the potential gain is approximately 6.3 MMUSD/year.
