Description
technical field [0001] The invention relates to a feeding device for a smelting blast furnace, which belongs to the field of metal smelting equipment. Background technique [0002] Blast furnace smelting method is the main method of modern ironmaking and an important link in iron and steel production. This method was developed and improved by ancient shaft furnace ironmaking. The feeding device of the smelting blast furnace is an important part of the whole blast furnace smelting system, which maintains the production of pig iron, energy consumption, smelting cost and the operation of the blast furnace. However, the existing feeding devices for smelting blast furnaces have the following problems: 1. The feeding of a single barrel can only be performed after the material in the barrel is loaded, which affects the efficiency; 2. The thickness of the blanking is not Even, resulting in a decline in the quality of molten iron. Contents of the invention [0003] The technical...
