Problems solved by technology

[0002] At present, a large amount of silicon-manganese waste slag will be produced in the production process of smelting silicon-manganese alloy in high-temperature electric furnace, and about 2 tons of silicon-manganese waste residue will be produced for the production of one ton of silicon-manganese alloy. Therefore, accumulation can be seen in silicon-manganese alloy production enterprises The mountains of silicomanganese waste slag take up a lot of space; secondly, the silicomanganese waste slag is stacked in the open air, causing environmental pollution

Abstract

This invention discloses a process method for SiMn fag-end and its usage, which processes large quantities of SiMn fag-end generated from the production process of smelting SiMn alloy by high-temperature oven then utilizes them comprehensively to turn them to precious matters, reduce the production fields occupied by them, and eliminate the pollution to the environment.

Description

technical field [0001] The invention relates to a treatment method and application of silicomanganese waste residue. Background technique [0002] At present, a large amount of silicon-manganese waste slag will be produced in the production process of smelting silicon-manganese alloys in high-temperature electric furnaces. The production of one ton of silicon-manganese alloys will produce about 2 tons of silicon-manganese waste residues. Therefore, accumulation can be seen in silicon-manganese alloy production enterprises. The mountains of silicomanganese waste slag take up a lot of space; secondly, the silicomanganese waste slag is stacked in the open air, causing environmental pollution. Contents of the invention [0003] The object of the present invention is to provide a treatment method and comprehensive utilization technology of silicomanganese waste residue. [0004] The purpose of the present invention is achieved in the following manner: [0005] A kind of proce...
