Refractory castable for desulfurization spray gun
The invention relates to a refractory castable for a desulfurization spray gun, the refractory castable comprises flint clay, andalusite, alumina and white corundum, particles of 5-3mm and 3-1mm in the andalusite are pre-sintered andalusite particles, the pre-sintering temperature is 1290-1350 DEG C, and the pre-sintering time is 2.5-4 hours. The method is suitable for a wide range of molten steel temperature and can well adapt to 1260-1420 DEG C, and the average service life of the desulfurization spray gun is prolonged by more than 10 furnaces under the condition that the structure of the spray gun is not changed.
本发明涉及一种脱硫喷枪用耐火浇注料，组成成分包括焦宝石、红柱石、矾土、白刚玉，所述红柱石中5～3mm、3～1mm的颗粒料为预烧后的红柱石颗粒料，预烧温度为1290℃～1350℃，预烧时间是2.5～4h。本发明适用钢水温度较广，可以较好的适应1260℃‑1420℃，在不改变喷枪结构的情况下，使脱硫喷枪的平均使用寿命提高10炉以上。
