Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to a metallurgical feeding device. Background Art

[0002] Metallurgy has a long history of development. Metallurgy is the process of removing impurities (unintended elements) in metal solutions by melting (heating to above the melting point) to form slag and remove slag. At the same time, some chemical components are removed by slag removal, decarburization, deoxidation, etc. to obtain relatively pure alloy components. Metallurgy requires.

[0003] In the prior art, a metallurgical furnace is usually used to smelt powdered raw materials to achieve a better metallurgical effect. The stored powdered raw materials are fed into the metallurgical furnace through a feeding device. However, the powdered raw materials are prone to agglomeration during storage, and directly feeding them into the metallurgical furnace will reduce the metallurgical efficiency. To this end, we propose a metallurgical feeding device. Utility Model Content
