This product is made of high-purity raw materials, molded through vibration, and baked under low-temperature.

The upper/down nozzle are mainly made of sintered corundum, fused corundum, fused mullite, and other raw materials.

The upper/down nozzle are mainly made of sintered corundum, fused corundum, fused mullite, and other raw materials.

This product is mainly made of tabular corundum, fused corundum, zirconia corundum, zirconia mullite, and other raw materials. By adding an appropriate amount of metal micro and fine powder through high-temperature reaction, the high-temperature performance of the slide gate is improved. An appropriate amount of micro powder such as boron carbide is added to improve the oxidation resistance. Phenolic resin with high solid content and high residual carbon is used as a binder, which is high-pressure formed by a press and processed at an appropriate temperature.
