Abstract
The invention discloses a barium-silicon-iron alloy production process which is characterized in that raw materials such as silica, barite, lime, coke, scrap iron and the like are mixed and then directly injected into an ore-smelting furnace to produce by a carbothermic method by adjusting process parameters and raw material proportion, and the defects of high energy consumption, high cost, low Ba and Si recovery rate and the like of the existing barium-silicon-iron alloy two-step production process are overcome. The process can be applied to various iron alloy plants.
Description
The present invention relates to a kind of method of producing ferrous alloy containing barium and silicon.
Ferrous alloy containing barium and silicon is subjected to increasing attention at home and abroad as a kind of efficient and long-acting nucleating agent, and at present, the method for producing ferrous alloy containing barium and silicon both at home and abroad is to adopt two step method: promptly earlier raw materials such as silica, iron filings, coke are reacted generation 75 in the hot stove in ore deposit
#Ferrosilicon is then with 75
#Ferrosilicon, barite are that main raw material is used electro-silicothermic process reducing and smelting ferrous alloy containing barium and silicon in medium-frequency induction furnace.The weak point of this production method is: barium, the element silicon rate of recovery are low, and one time production lot is few, and the energy consumption height, cost is big, equipment requirements is tight.
The problem that the present invention is directed to above-mentioned existence proposes a kind of simple to operate, efficient, energy-conservation, barium ferrosilicon production method of not needing specific installation.
By a large amount of experiments, we find by adjusting process parameter and raw material ratio, once add in the hot stove in ore deposit after all raw material is mixed and also can produce ferrous alloy containing barium and silicon, and promptly " single stage method " produces ferrous alloy containing barium and silicon, with production 75
#The ferrosilicon method is basic identical.
" single stage method " production ferrous alloy containing barium and silicon flow process is as follows:
Wash with sub-sieve after silica, the barite pulverizing and with flowing water earlier, simultaneously with broken back such as lime, coke, iron filings sub-sieve, again the raw material mixing intermittent type behind twice sub-sieve is added in the hot stove in ore deposit and smelt, regularly tap a blast furnace after a period of time, ingot casting, finishing tough warehouse-in.The various raw-material technical requirements of producing alloy is:
Barite deposit contains BaSO
4〉=90%, granularity 10-50mm.
Silica mine contains SiO
2〉=98%, Al
2O
3≤ 0.15%, granularity 20-80mm.
Lime contains CaO 〉=80%, granularity 10-30mm.
Coke contains C
Gu〉=80%, ash≤6%, granularity 2-100mm.
Iron filings contain Fe 〉=95%, and are rustless, length≤100mm.
The proportioning of each main raw material(s) is respectively (mass percent):
Silica 58%, barite 2.3%, coal 1.7%, coke 31.3%, iron filings 6.7%
The operation key is: spare no effort to thin lid, duty is dazzling, regularly smashes stove, and the assurance charge level is evenly burned with anger, and barium ore is given in the thermosphere at furnace charge fully decompose, and correct the grasp tapped a blast furnace the time, and the temperature and the molten iron temperature of coming out of the stove in the stove are controlled in strictness.
Adopt positively effect of the present invention to be that producing ferrous alloy containing barium and silicon with existing " two step method " compares and have the following advantages: power consumption reduces by 40%, and the barium element recovery rate improves 2.16 times, and cost reduces by 25%, and production unit only needs the hot stove in ore deposit, does not need medium-frequency induction furnace.
Embodiment:
Adopt the present invention to produce ferrous alloy containing barium and silicon (the hot furnaceman in ore deposit plant parameter select see Table 1) in two hot stoves in ore deposit respectively, the product Chemical Composition of producing sees Table 3, basically whole conformance with standard (standard sees Table 2, standard No. B/T227-89).
