The different metallurgical materials also determine their different functions. Therefore, when choosing to purchase, you should also choose according to your own actual requirements. How much do you know about silicon barium calcium? Next, we will briefly introduce it to you.
The calcium silicate barium can be used as deoxidizer, and the effect is good as a desulfurizer, and the dephosphorization can also meet the requirements. The preparation method of calcium silicate barium inoculant is mainly the following steps: first, break the chromium alloy, calcium silicate, and phosphide into 2mm to 6mm particles, and then mix them according to the example of 1500 to 2500; Melt the mixture at 1500 ℃ for 5 minutes and then cool it; The obtained cooled mixture and manganese vanadium nitride are atomized into powder in the mass ratio of 2000 to 1000; In a nitrogen protected high temperature furnace, the block is sintered in multiple systems to obtain the sintered mixture; The sintered mixture and silicon barium alloy are mixed and broken by mechanical mixing method in a mass ratio of 1000 to 100. Barium reduces the vapor pressure of calcium in the range of steelmaking temperature, which can increase the solubility of calcium in molten steel. The average post furnace oxygen is 372.4 ppm, the average deoxidization is 2.327 ppm/kg deoxidizer, the average cooling rate is 3.92 ℃/min, and the silicon increase efficiency is 74.85%. The deoxidizing effect, silicon increasing efficiency and cooling rate of silicon barium calcium alloy deoxidizer are better than those of the original silicon calcium composite deoxidizer. It can be seen that the application of silicon barium calcium is relatively extensive, and the development prospect is also very good
