Abstract
The invention relates to a method for producing 431-type smelting flux, which is used for producing the 431-type smelting flux and uses hot slag of manganese iron production. The smelting flux is produced from the following materials in portion by weight: 45 to 55 portions of hot slag, 15 to 20 portions of auxiliary materials and 20 to 30 portions of manganese ore, wherein the auxiliary materials comprise the following components in portion by weight: 180 to 220 portions of quartz, 55 to 65 portions of calcium fluoride and 75 to 85 portions of magnesium oxide. The method comprises the steps of: adding the hot slag into the auxiliary materials to carry out stirring oxidization reaction; after the materials in a furnace become clear, adding the manganese ore into the auxiliary materials to continuously carry out the oxidization reaction, and heating the mixture to between 1,250 and 1,350 DEG C; and after the color of the mixture becomes brownish red, taking the mixture out from the furnace and carrying out water quenching on the mixture to form the 431-type smelting flux. The method has the advantages of low consumption of the manganese ore, low power consumption, short production period, high production efficiency, few harmful components, high purity, stable product quality and high yield.

3≤ 4% and P≤0.1%.
At present, what the production of fysed flux was adopted is the method for melting manganese ore, and the manganese ore consumption is big, the power consumption height, and the production cycle is long, and production efficiency is low, and, the objectionable constituent height, unstable product quality, yield rate is low.
Summary of the invention
The object of the present invention is to provide a kind of production method of 431 type fysed fluxes, the manganese ore consumption is little, and power consumption is low, and is with short production cycle, the production efficiency height, and also objectionable constituent are few, purity height, constant product quality, yield rate height.
The production method of 431 type fysed fluxes of the present invention, make through batching, melting and shrend, it is characterized in that utilizing ferromanganese to produce warm sludge and carry out melting production, materials weight consists of: warm sludge 45-55 part, auxiliary material 15-20 part and manganese ore 20-30 part, wherein auxiliary material weight consists of: quartzy 180-220 part, Calcium Fluoride (Fluorspan) 55-65 part and magnesium oxide 75-85 part.
Warm sludge is the warm sludge that manganese, iron are produced, and at fysed flux of the present invention, the active constituent content in the warm sludge is higher, and weight content is: Al
2O
310%, MnO 30%, SiO
235%, the impurity of MgO 6%, CaO 4% and surplus, thereby can obtain that objectionable constituent are few, purity is high, the fysed flux of constant product quality.Directly utilize ferromanganese to produce warm sludge, saved the day by day deficient manganese ore of resource on the one hand, made full use of waste residue on the other hand, turned waste into wealth, avoided the exhaust emission of waste residue and taking the good farmland, and, also make full use of the waste heat of warm sludge, saved the power consumption of melting, also shortened the heat temperature raising time, shortened the production cycle, the yield rate height
During operation, warm sludge joined stirs oxidizing reaction in the auxiliary material, treat furnace charge become clear after, add manganese ore again and proceed oxidizing reaction, and heat to 1250-1350 ℃, treat that color is red-brown, the shrend of coming out of the stove promptly gets fysed flux of the present invention.
Used manganese ore is common manganese ore raw material, and MnO weight content wherein requires to reach more than 30%, and is high more good more.
The production method of the present invention's 431 type fysed fluxes, directly produce warm sludge instead of part manganese ore and carry out melting production with ferromanganese, the manganese ore consumption is little, saves manganese ore and reaches 80%, and power consumption is low, save power consumption and reach 60%, also shorten the production cycle greatly, improved production efficiency, and, the fysed flux harmful component of product that obtains is few, purity is high, constant product quality, yield rate height, economic benefit and obvious social benefit.
The chemical weight percentage composition of the fysed flux product that the present invention obtains is: SiO
241-45%, MnO35-39%, CaF23-4%, MgO5-7.5%, CaO≤4.0%, FeO≤0.5%, S≤0.05%, Al
2O
3≤ 2% and P≤0.05%.
