One Of High Level Products Silicon Barium

A silicon barium magnesium manganese iron alloy and its preparation method, the key points are: adding barium, magnesium, and manganese to silicon iron alloy, reduced and smelted into a silicon barium magnesium manganese iron alloy in a submerged arc furnace. Its chemical composition is: Si 30-70%, Ba 5-30%, Mg 1-10%, Mn 1-9%, Fe and unavoidable impurities 10-40%; using an exothermic method for secondary melting of the silicon barium magnesium manganese iron alloy, adding feldspar during the secondary smelting process. The positive effects include enhancing the density of the alloy, solving the problems of porosity and powdering of the alloy; furthermore, after adding feldspar and iron oxide in this invention, it can also be suitable for low-aluminum alloy steel such as electrical silicon steel sheets.

1.A silicon barium deoxidizer for steelmaking and its preparation method, with the weight proportions of raw materials as follows: 70-75 parts quartz sand, 30-40 parts barite, 5-10 parts feldspar, 10-15 parts fluorite, 15-20 parts aluminous vanadium clay, 3-5 parts charcoal, and 20-25 parts vermiculite. The formula is reasonable, using feldspar, fluorite, aluminous vanadium clay, charcoal, and vermiculite as raw materials. This deoxidizer has good deoxidation effects, can reduce the content of non-metallic inclusions in steel and change the morphology of inclusions, purifying the molten steel, improving the fluidity of molten steel, ensuring a smooth continuous casting process without the occurrence of clogging at the casting nozzle, facilitating smooth production in refining and casting, enhancing the performance and lifespan of steel, and reducing steelmaking costs.
