Product details
Aluminum-zirconium-carbon products are used in workshop with preheating conditions. The main features of products :certain oxidation resistance, thermal shock resistance, strong erosion resistance and corrosion resistance, and are suitable for multi-heat and long-term continuous casting. Improve the quality of steel, save energy, and greatly reduce production costs.
