Abstract
Si-al-ba-fe is a kind of novel composite deoxidant.This alloy is mainly used in the deoxidation and the alloying of STEELMAKING PRODUCTION.Use this alloy deoxidation and alloying, not only reduce the steel inclusion total amount, change the inclusion shape, the quality of the size and the raising steel that distributes, and 1: 1 replacement Alsimin of energy, 1: 2.1 replacement metallic aluminium, can reduce the usage quantity of aluminium greatly, the production cost of steel is descended.
Description
The invention belongs to alkaline-earth metal production NEW TYPE OF COMPOSITE deoxidant Si-Al-Ba-Fe alloy alloy.Producing si-al-ba-fe with alkaline-earth metal is a kind of new method, and si-al-ba-fe is a kind of new alloy material, is mainly used in deoxidation and alloying in the STEELMAKING PRODUCTION process.
The reductor that is used for STEELMAKING PRODUCTION now mainly is metallic aluminium and Alsimin.Existing alloy generates strip high-melting-point Al with the molten steel reaction in deoxidation in steel making and alloying process
2O
3Be mingled with, influence the quality of steel, reduce the impelling strength and the unit elongation of steel.Increase the cost of steel with metallic aluminium, ferro-aluminum and ferrosilicoaluminum deoxidation.
The purpose of this invention is to provide a kind of new method alkaline-earth metal is made si-al-ba-fe, the shape, size and the distribution that change inclusion in deoxidation in steel making and alloying process improve the quality of steel.Deoxidation metallic aluminium, Alsimin and ferroaluminium composition such as table 1:
Major technique of the present invention is with the synthetic at twice alloy of alkaline-earth metal.At first prior barite material (seeing table 2 for details) through processing is packed in the ore reduction stove by certain proportioning (seeing table 3 for details), then with the stable furnace charge suitable position that is placed on of electrode, furnace charge decline and gas are discharged evenly, and play iron notch easily, make Si-Ba alloy (seeing table 4 for details).With Si-Ba alloy and metallic aluminium and steel scrap synthesizing Si-Al barium iron (Fe-Ba-Al-Si) alloy in induction furnace made, its composition sees table 5 for details.
The present invention is used for deoxidation in steel making and alloying, can change shape, size and the distribution of inclusion, improves the impelling strength and the unit elongation of steel, reduces the steel inclusion content more than 30%.This alloy can 1: 1 the replacement Alsimin, 1: 2.1 replacement metallic aluminium can be saved metallic aluminium more than 55%.
Trial-manufacturing process of the present invention is as follows: the lumpiness that barite is crushed to 20～120mm, pack in the ore reduction stove by the proportional quantity of table 3 with quartzite, iron filings, Wingdale, calcium carbide, coke then, and be placed on the furnace charge deep with electrode is stable, produce Si-Ba alloy.With Si-Ba alloy and metallic aluminium and the steel scrap synthesizing Si-Al barium-ferrum alloy of making in induction furnace.
Claims (5)
1, a kind of NEW TYPE OF COMPOSITE deoxidant Si-Al-Ba-Fe alloy alloy of producing by alkaline-earth metal.It is characterized in that: select different raw materials and ratio of components for use, form with ore reduction stove and the induction furnace system of closing at twice.
2, alloy as claimed in claim 1, its Chemical Composition is: the Fe-surplus; Ba-3～12%; Al-30～40%; Si-22～28%.
3, according to claim 1, producing this alloy materials and proportioning is: barite 20～30%; Quartzite 60～70%; Iron filings 10～15%; Calcium carbide 1～2%; Wingdale 2～3%; The coke whatever you like.
4, alloy as claimed in claim 1 is to form with ore reduction stove and the induction furnace system of closing for twice.Earlier produce Si-Ba alloy, produce si-al-ba-fe with induction furnace again by the ore reduction stove.
5, according to claim 1, adopt calcium carbide to make solvent and reductive agent.
