Anti-corrosion Silicon nitride Riser Tube for foun

Silicon nitride riser tube has many excellent characteristics, such as corrosion resistance, low thermal-expansion coefficient and long service life .It is the ideal materials of the metallurgy industry because of the excellent oxidation resistance, heat-shock stability and no reaction with the metal solution. The thermal-expansion coefficient of the silicon nitride is 1.0×10-6/ deg ,the flexural strength is 80 90mpa .After using ,not only can improve the quality of the casting products but also can reduce the cost. The service life of the silicon nitridestalk tube is 5-20 times longer than the traditional lift tube, so the replacement of the lift tube is reduced and the continuous of the production is ensured. Now the silicon nitride lift tube is widely used in the aluminum smelting industry,petroleum chemical industry, ceramic industry and electronics industry. Silicon nitride ceramics possess excellent properties of high thermal stability, antioxidant capacity and good dimensional precision of products. It can be used to make combustion chamber in gas turbine, mechanical sealing ring, pipes and valves of electromagnetic pump for transmitting molten aluminium, permanent mold and the separation ring for molten steel. It can be used as the parts in projects of high temperature, senior refractory of metallurgical industry, anticorrosion parts and sealing parts in chemical industry and cutters in mechanical process industry. OEM is acceptable. Pls kindly check our silicon nitride products for your reference: Welcome to inquiry us!
