Development of Waste Plastics Pulverization for Blast
In the blast furnace, molten pig iron is produced by a process in which a hot blast with a temperature of approximately 1 200°C is blown into the furnace through tuyeres around the furnace bottom, and coke descending from the top is converted to a reducing gas, which reduces and melts the iron
