Abstract
The invention discloses a silicon-aluminum bentonite steelmaking deoxidizer and a preparation method thereof. The silicon-aluminum bentonite steelmaking deoxidizer comprises the following raw materials in parts by weight: 50-55 parts of quartz sand, 5-10 parts of dolomite, 20-25 parts of limestone, 10-15 parts of bentonite, 3-5 parts of scrap iron, 3-5 parts of waste aluminum powder, 5-10 parts of attapulgite, 6-12 parts of vermiculite and 6-10 parts of black manganese ore. The silicon-aluminum bentonite steelmaking deoxidizer disclosed by the invention has the advantages that a formula is reasonable and the scrap iron, the waste aluminum powder, the attapulgite and so on are added into the raw material, so that the deoxidizer is good in deoxidizing effect, the content of nonmetal impurities in steel can be reduced, the forms of the impurities can be changed, molten steel is purified, the liquidity of the molten steel is improved, the continuous casting process of a molten steel blank is smooth, and no accretion is generated at a continuous casting nozzle, thus, the smooth casting production is facilitated, the use performance of the steel is improved and the service life of the steel is prolonged; and the steelmaking cost is reduced.
Description
Technical field
The present invention relates to a kind of steelmaking technical field, be specifically related to a kind of sial wilkinite steel making deoxidant and preparation method thereof.
Background technology
At present, the reductor of using in the domestic industry STEELMAKING PRODUCTION process mainly is calcium, aluminium or iron alloy etc.; Deoxidation effect generally reaches the 60-100PPM rank, and effect is general, and continuous casting of molten steel base process has some setbacks sometimes; The continous casting sprue dross, observing casting blank section has bigger bubble and slag inclusion, and cost is higher.
Summary of the invention
The object of the present invention is to provide a kind of sial wilkinite steel making deoxidant and preparation method thereof; The present invention fills a prescription rationally, has added iron filings, aluminium scrap powder, attapulgite etc. in the raw material, and deoxidation effect is obvious; Can effectively remove the inclusion in the molten steel, improve Molten Steel Flow property.
The present invention adopts following technical scheme to achieve these goals:
Sial wilkinite steel making deoxidant, the weight part of its constitutive material is: silica sand 50-55, rhombspar 5-10, Wingdale 20-25, wilkinite 10-15, iron filings 3-5, aluminium scrap powder 3-5, attapulgite 5-10, vermiculite 6-12, hausmannite stone 6-10.
Sial wilkinite steel making deoxidant, the weight part of its constitutive material is: silica sand 52, rhombspar 5-10, Wingdale 22, wilkinite 12, iron filings 4, aluminium scrap powder 4, attapulgite 8, vermiculite 9, hausmannite stone 8.
The preparation method of sial wilkinite steel making deoxidant may further comprise the steps: the weight part by constitutive material takes by weighing each raw material, mixes the 2500-3000 ℃ of high temperature in back and smelts 2-3 hour down, and 2-3 hour, cooling, fragmentation obtained.
Beneficial effect of the present invention:
The present invention fills a prescription rationally, has added iron filings, aluminium scrap powder, attapulgite etc. in the raw material, and this reductor has good deoxidation effect; Can reduce the content and the form that changes inclusion of nonmetallic inclusionsin steel, cleaning molten steel improves fluidity molten steel; Continuous casting of molten steel base process is smooth and easy; Dross does not appear in continous casting sprue, helps the refining casting and produces smoothly, has improved steel use properties and life-span.Reduced steel-making cost.
