Application technology of silicon carbide waste to ferrosilicon and silicomanganese production

Abstract

The invention discloses an application technology of silicon carbide waste to ferrosilicon and silicomanganese production. The application technology comprises the following steps that A, the waste iscollected, specifically, the impurity waste is collected outside a silicon carbide crystallizing barrel; B, the waste is processed, specifically, circular processing and grinding are performed on thewaste through a waste processing device, ground waste is collected, relevant impurities are removed, and obtained waste is stored for a standby purpose; and C, ferrosilicon and silicomanganese raw materials are mixed, specifically, manganese ore, manganese sintering ore, rich-manganous slag, silica, dolomite or limestone, a reducing agent and the silicon carbide production waste are mixed according to a proportion. Silicon carbide smelting raw materials, quartz sand and anthracite belong to quality raw materials with the high purity and low impurity content, the silicon carbide production waste belongs to semi-finished materials, electric consumption can be reduced, the structures of microelements in ferrosilicon and silicomanganese can be changed, the waste of silicon carbide factories can be comprehensively utilized, higher value is created, resource recycling is achieved, the resource recycling rate is increased, and the application technology is environment friendly.

Description

Technical field: [0001] The invention belongs to the technical field of production of ferrosilicon and silicon-manganese alloys, and in particular relates to an application process of silicon carbide production waste in the production of ferrosilicon and silicon-manganese alloys. Background technique: [0002] During the silicon carbide smelting and production process, 100mm-200mm magazine waste is formed outside the silicon carbide crystallization cylinder, accounting for about 15% of the finished product output of silicon carbide. The waste can be comprehensively utilized, but it cannot reduce the power consumption per unit of finished product, cannot improve the content of trace elements in the alloy, cannot realize energy recycling, cannot increase the recycling rate of resources, and cannot achieve green environmental protection. Invention content: [0003] The purpose of the present invention is to provide an application process of silicon carbide production waste in...
