Refractories Co., Ltd., Zhengzhou City shangzhuang learned as refractories, the development of a special refractory and high temperature technology, particularly the development of the metallurgical industry closely related. The rapid development of the structure of various emerging technologies are urgently needed Gao temperature resistant material having high strength and excellent performance of functional materials. This requires the development of new metal, special alloys and semiconductor materials, while these new metals and semiconductor materials is very high purity requirements. However, when these materials are refractory smelting preparing quotations, often at the melting temperature of the refractory material will react with ordinary being eroded; the quality of the metal container not suitable as these materials are melted, distillation, Rao, alloying process receptacles or crystal growth of container, metal containers because they will pollute the smelting material, refractory material, must develop a new type of high-temperature 'corrosion of refractories. Refractories Co., Ltd., Zhengzhou City shangzhuang learned in today's increasingly scarce national resources refractories wholesale, new green and energy saving has become the purpose of development of refractories. Currently refractory distributor, Europe, Japan, the United States and other countries and regions due to mandatory government has basically no chromium refractories, refractory materials using green has become an inevitable trend. Refractories Co., Ltd., Zhengzhou City shangzhuang also strengthen co-operation with research institutions and user units, increase research cooperation efforts in the green refractory technology to achieve new breakthroughs.
