Embodiment Construction

[0010] The present invention will be further described below in conjunction with embodiments.

[0011] The reducing agent for smelting chemical-grade metallic silicon of the present invention includes silica, petroleum coke and bituminous coal, wherein the mass ratio of silica to the total fixed carbon content in the reducing agent is maintained between 2.7:1.3-2.9:1.1. In the first embodiment of the present invention: ingredients are carried out according to the following ingredient comparison,

[0012] (1) Ingredients: in parts by weight, silica: about 56 parts, petroleum coke: about 19 parts, bituminous coal: about 16 parts, wood block: about 9 parts, wherein the silica particle size range is 50-100mm; bituminous coal The particle size range is 1-30mm, and the petroleum coke particle size range is 1-20mm;

[0013] (2) Mixing: Mix the above-mentioned raw materials together to make them uniform;

[0014] (3) Feeding: Put the mixed materials into the smelting furnace at regular in...

Abstract

The invention relates the reducing agent of smelting chemical grade metallic silicon, comprising ganister, oil coke and bituminous coal. The mass ratio of ganister and fixed charcoal content is between 2.7:1.3 and 2.9:1.1. The invention has the advantages of reducing the cost of metallic silicon and good economic benefit and social benefit.

Description

Technical field [0001] The invention relates to a chemical reducing agent, in particular to a charcoal-free reducing agent used in the process of smelting chemical grade metallic silicon. Background technique [0002] Industrial silicon has a wide range of uses, mainly used in fine chemicals, metallurgy, electronic information and other industries. In the chemical industry, industrial silicon is mainly used to produce organic silicon (such as silicone oil, silicone rubber, silicone resin, silicone coupling agent, etc.) products. In the metallurgical industry, it can be used as an additive and deoxidizer for iron-based alloys, an alloying agent for silicon steel, and silicon aluminum alloy. Its products are widely used in national defense and civil industries. In the electronic information industry, it is mainly used to produce monocrystalline silicon, polycrystalline silicon and semiconductor materials. It is an essential raw material for modern industries, especially high-tech i...
