Online fusion production method of manganese-silicon alloy powder

Abstract

The invention discloses an online fusion production method of a manganese-silicon alloy powder. The method comprises steps of powder recovery, bottom pouring, powder addition and fusing, cover casting, stirring and fusing, iron fetching and mold stripping, transfer and crushing and the like. The method is remarkably characterized in that during the manganese-silicon alloy casting process, molten iron is poured by fractional ''bottom pouring'' and ''cover casting'' and an alloyed powder is added into an ingot mould to carry out heat exchange; and then, the alloyed powder is fused by heat absorption and fused in the molten iron, and an alloy ingot is prepared after condensation. On the precondition of not increasing power consumption, heat of the high-temperature molten iron is utilized to carry out online fusion treatment on the alloyed powder generated by crushing of an ingot. Meanwhile, the time of molten iron condensation and ingot formation can obviously be accelerated, and production operation time can be shortened. The method provided by the invention has obviously effects of enhancing recycling rate of the main element Mn, improving the condition of chemical composition segregation and further raising product quality. When popularized and applied in the manufacturing industry of Mn alloys, the method has social effects of saving energy, reducing emission and protecting the environment as well as great economic benefit.

Description

technical field [0001] The invention relates to a production method for on-line molten manganese-silicon alloy powder, which adopts the method of on-line melting and recovery of manganese-silicon alloy powder in the premise of not increasing energy consumption, which can minimize the manganese element due to furnace The volatile heat loss of internal smelting and the physical loss caused by flying powder particles have obvious effects on energy saving, consumption reduction, effective utilization of manganese resources, and reduction of comprehensive production costs of manganese-silicon alloys. Background technique [0002] In the manganese alloy production industry, the amount of powder produced by crushing and processing manganese-silicon alloy ingots varies according to the difference in crushing and processing methods. According to production statistics: the powder rate of particle size ≤ 10mm is usually 6-15 %between. Manganese-silicon alloy powder is characterized by...
