Problems solved by technology

The above three ferromanganese alloy production processes are mature, but there are the following problems: (1) The process flow is long, the environment is seriously polluted, and the cost is high. Generally, it is necessary to process and sinter manganese raw ore to improve the grade of manganese ore, and then carry out blast furnace or electric furnace smelting; (2) The blast furnace process has high requirements on the quality of manganese ore, and the variety is single, while the submerged arc furnace method produces ferromanganese, which consumes a lot of power and costs more, which is subject to the power supply situation
The equipment investment of the two processes is large, the floor area is large, the production management is complicated, the production cycle is long, and the production efficiency is low.

Abstract

A manganese alloy preparing process for metallurgical steelmaking and mechanical casting. It is prepared by manganese ore adding electronating agent, exothermal agent and catalyst, breaking and grinding into particle powder material, proportional mixing and adding binder to prepare composite manganese alloy palletizing; smelting composite manganese alloy into liquefied slag containing manganese by vertical furnace or cupola, converting into arc furnace, inducing furnace with electroslag furnace, preparing different slag system under arc furnace electrode or inducing coil and electroslag furnace electrode heat, reducing combined manganese in liquefied slag containing manganese into intermetallic combined manganese alloy. Its advantages include no pollution, low consumption and high efficient.

Description

technical field [0001] The invention relates to a production process of manganese alloy used in metallurgical steelmaking and mechanical casting industries. Background technique [0002] At present, when manganese is alloyed in the production process of metallurgical steelmaking or the production of manganese-containing alloys, ferroalloys containing manganese are generally used, such as ferromanganese (Fe-Mn) and ferrosilicon manganese (Si-Fe-Mn). Manganese alloying is carried out when tapping. There are three main production processes for this type of ferromanganese alloy: one is to use the sintered blast furnace process, that is, blast furnace ferromanganese; the other is to use the sintered submerged arc furnace (electric furnace) process, that is, electric furnace ferromanganese; Manganese slag) + submerged arc furnace process, that is, silicon-manganese alloy. The above three ferromanganese alloy production processes are mature, but there are the following problems: ...
