Abstract:
Coke plays a fundamental role in the reduction process of Blast Furnaces, where moisture content is significantly important, because its elimination provides an endothermic reaction, stealing oven heat, which can generate losses in mass balance and pig iron production. The analysis of the factors that affect the moisture content of coke in steel mills that have a wet quenched system is a topic that is widely discussed internally. Many measures are taken to reduce coke moisture, such as the use of batch compositions, coke preparation techniques and parameters, wet quenched system settings in quenching towers so that whole coke charge in the charging car is uniformly cooled, cleaning of water nozzles, uniform distribution of coke on the ramp; residence time of the coke in the ramp until the end of the flow to the Stock House bins. This work aims to show the influences of coke moisture content from its wet quenching in the Coke Plant to the supply of blast furnaces
