Abstract

The invention relates to the field of treatment of slag produced in production or refining of metals, specifically to a refining apparatus for silicon manganese alloy tailings and an application method thereof. The refining apparatus for silicon manganese alloy tailings comprises a silicon manganese alloy slag outlet (1), a melting furnace (2), a metal casting machine (3) and a microcrystalline glass molding machine (4), wherein the discharge outlet of the silicon manganese alloy slag outlet (1) is arranged just above the feed inlet of the melting furnace (2). The refining apparatus is characterized by further comprising a mixer (5), a fixed-weight feeder (6), an accessory material bin (7), a reducing agent warehouse (8) and an elevator (9). The application method for the refining apparatus is characterized in that an accessory material, a reducing agent and slag are heated to at least 1600 DEG C in the melting furnace (2) and calcined, and molten ferromanganese and slag are respectively discharged through the iron outlet and the slag outlet of the melting furnace (2). With the apparatus and the method in the invention, the utilization rate of energy and resources is high, and good environmental protection performance is realized.

Description

technical field [0001] The invention relates to the field of processing slag during metal production or refining, in particular to a refining device for silicon-manganese alloy tailing slag and a method for using the same. Background technique [0002] Silicon-manganese alloy is an alloy composed of manganese, silicon, iron, a small amount of carbon and other elements. It is a ferroalloy with wide application and large output. It is an important composite deoxidizer and alloy additive in iron and steel smelting. In the production process of silicon-manganese alloy, the tailings contain a relatively high proportion of SiO 2 and MnO 2 , while the high-temperature tailings are rich in heat energy, and the SiO in the tailings 2 Various types of glass-ceramics can be directly produced after proper tempering. Compared with the existing glass-ceramics produced with cold slag or natural minerals as raw materials, the physical sensible heat of tailings can be fully utilized by usin...
