AI Technical Summary

Technical Problem

The existing ingot mold capacity is small, which limits the amount of casting per batch and requires frequent mold replacements. This makes it difficult to meet the needs of large-scale continuous casting of industrial silicon, and the high-temperature oxidation resistance is insufficient after increasing the ingot mold capacity.

Method used

The mold frame is made of HTRCr heat-resistant cast iron and the masonry layer is made of silicon nitride combined with silicon carbide bricks. This increases the mold capacity and improves the high-temperature oxidation resistance by mixing mud materials. The stability is enhanced by the combination of lifting lugs and reinforcing ribs.

Benefits of technology

It improves the capacity and high-temperature oxidation resistance of the ingot mold, increases the casting volume, avoids high-temperature damage, achieves uniform distribution of thermal stress, and improves production efficiency and product quality.
