Description

technical field [0001] The invention relates to a sintering process in iron and steel metallurgy, in particular to a multifunctional high-efficiency sintering cup experimental device and method. Background technique [0002] Sintering technology is currently the most widely used iron-containing raw material agglomeration method in domestic and foreign iron and steel enterprises. After sintering, fine ore and various iron-containing solid wastes can become iron-containing raw materials that meet the requirements of blast furnace ironmaking (high grade, less harmful impurities, good reducibility, excellent high-temperature performance, good strength, suitable particle size, stable and uniform chemical composition) . In order to study and master the principles and methods of iron ore powder sintering and optimize the sintering process, a large number of sintering experiments are required in the laboratory. Through a large number of sintering cup experiments to study the influ...
