[0002] After the metallic silicon solution is refined, it needs to be cast and shaped to facilitate subsequent processing. Currently, 80% of industrial silicon companies use cast iron ingot molds. The temperature of the metallic silicon solution is around 1600-1700°C, and the maximum temperature resistance of cast iron is 1400°C. Therefore, during use, the cast iron ingot mold will be continuously corroded by high temperature, which not only affects its service life, but also the formed oxide scale will fuse with the metallic silicon, affecting the quality of the metallic silicon.
