The different metallurgical materials also determine their different roles, so when choosing to buy, but also according to their own actual requirements to choose, so we know how much about silicon barium calcium? The next is a simple introduction for you.
Silicon barium calcium can be used as deoxidizer for, as the desulfurizer effect also is pretty good, dephosphorization can also meet the requirements, method of preparation of calcium silicon barium inoculant is mainly the following steps, the chromium alloy, calcium silicon, phosphide first broken into 2 mm to 6 mm particles, after mixing well-founded sex-discrimination than 5, one thousand five hundred - two thousand five hundred; The resulting mixture was melted for 5 minutes at a temperature of 1500 degrees Celsius and then cooled; The obtained cooling mixture and manganese vanadium nitride according to the mass ratio of 2000 to 1000 using atomization powder; The blocks were sintered in a nitrogen-protected high temperature furnace to obtain the sintered mixture. Mechanical mixing method was used to mix and break the sintered mixture with silicon barium alloy in the mass ratio of one thousand to one hundred. Barium can effectively reduce the vapor pressure of calcium in the temperature range of steel making, and can increase the solubility of calcium in the molten steel. The average post-furnace oxygen is 372.4ppm, the average deoxidation degree is 2.327ppm/kg deoxidizer, the average cooling rate is 3.92℃/ min, and the silicon increasing efficiency is 74.85%. The deoxidizing effect, silicon-increasing efficiency and cooling rate of silicon-calcium alloy deoxidizer are better than the original silicon-calcium composite deoxidizer. It can be seen that silicon barium calcium is widely used and has a very good development prospect. If you have any questions or needs about silicon barium calcium, you are welcome to call for consultation.
