Zhengzhou Sunrise Refractory Co., Ltd.
High quality silicon carbide refractory products have been developed by Zhengzhou Sunrise Technology Co., Ltd featuring high strength, high thermal conductivity, good thermal shock resistance and corrosion resistance etc. The main properties have been tested and evaluated by independent testing labs outside China, and the results are good. So far the products have been approved by a decade of large companies abroad, over 80% of its output have been supplied to more than 10 countries and regions, especially in Europe and America. Meanwhile the products have been supplied to many major enterprises in China such as nonferrous metallurgy industry and so on. As substitute of similar imported products, four varieties in this series have won the title of national grade high-tech product.
