Manganese-silicon alloy production system and technology

Abstract

Disclosed is a manganese-silicon alloy production system. The manganese-silicon alloy production system comprise a comprehensive material shed, a coke material shed, a proportioning station, a rotarykiln, a heat-preservation material tank and an electrical furnace; the comprehensive material shed is used for storing ores, and the ores comprise various manganese ores, silica, dolomite and sinteredores; the coke material shed is used for storing coke; the proportioning station is used for proportioning the various manganese ores, the silica and the dolomite to form a first mixed material, andused for proportioning the coke and the sintered ores to form a second mixed material; the rotary kiln is used for receiving the first mixed material from the proportioning station and calcining the first mixed material, the feeding end of the rotary kiln is arranged at the kiln tail, and the discharging end of the rotary kiln is arranged at the kiln head; the heat-preservation material tank is arranged on the lower portion of the discharging end of the rotary kiln, and used for receiving and storing hot materials from the discharging end of the rotary kiln, and receiving and storing the second mixed material from the proportioning station; and the electrical furnace receives the first mixed material from the heat-preservation material tank and the second mixed material from the proportioning station, and smelts the received mixed materials. The production system is high in heat utilization rate and high in electric furnace production capacity.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment and metallurgical technology, in particular to a manganese-silicon alloy production system and a manganese-silicon alloy production process. Background technique [0002] Manganese-silicon alloy is an alloy composed of manganese, silicon, iron, a small amount of carbon and other elements. It is a kind of alloy with wide application and large output. Manganese-silicon alloys are usually produced in electric furnaces, and the raw materials for producing manganese-silicon alloys include manganese ore (various types of manganese ore, manganese sinter), coke, silica, dolomite, etc. [0003] Domestic manganese ore is generally of low grade. In order to ensure the content of manganese element in manganese-silicon alloy products and smooth production, some higher-grade manganese ore should be matched. In order to balance cost and product quality, manganese-silicon alloy smelting often use...

AI Technical Summary

Problems solved by technology

Therefore, the traditional manganese-silicon alloy smelting process is complicated, the heat utilization rate is low, the power consumption is high, and the production capacity of the electric furnace is low.
