Production process of fused white corundum
The invention discloses a production process of fused white corundum. The production process comprises the following steps: S1, lifting industrial alumina powder through a pipeline and conveying the industrial alumina powder into an electric arc furnace; s2, electrifying the electric arc furnace to enable the temperature in the electric arc furnace to reach 2,000 DEG C to 2,500 DEG C, and heatingthe industrial aluminum oxide powder to be in a molten state; s3, pouring the aluminum oxide in the molten state into a receiving ladle, and carrying out primary cooling on the receiving ladle in thepouring process; s4, taking out the condensed frit, and sending the frit to a secondary cooling place; and s5, conveying the cooled frit to a crushing point, crushing the cooled frit for the first time, and crushing, thefirst time crushed corundum for the second time, wherein the whole process of closed feeding is adopted in the invention, so that the phenomenon of dust in the production process of white corundum is solved; and the production process is simple and the production efficiency is high; and multi-stage crushing and repeated crushing are adopted, so that the granularity uniformity of the produced white corundum is ensured.
本发明公开了一种电熔白刚玉生产工艺，包括以下步骤：S1、将工业氧化铝粉通过管道提升并输送至电弧炉内；S2、电弧炉进行通电，使电弧炉内温度达到2000℃‑2500℃，将工业氧化铝粉加热至熔融状态；S3、将熔融状态的氧化铝倒入接包中，在倾倒过程中对接包进行一次冷却；S4、将冷凝的熔块取出，并将熔块送至二次冷却地点；S5、将冷却完成后的熔块输送至破碎点，对冷却后的熔块进行一次破碎，将一次破碎后的刚玉进行二次破碎，本发明中采用全程封闭供料，解决了白刚玉生产过程中出现粉尘的现象；生产过程简单，生产效率高；采用多级破碎与重复破碎，确保生产的白刚玉的粒度均匀。
