1, Moulding: Cold isostatic pressing(CIP)
Silicon carbide tube with high density, impervious to water and air permeability, wear resistance, corrosion resistance, acid and alkali resistance, high temperature resistance, not easy to deformation, long life and other characteristics, can be used in copper, aluminum, zinc, alloy and other solutions! The inner diameter of the furnace hole through the silicon carbide tube should be 1.4 to 1.6 times the outer diameter of the cold end, and the furnace hole is too small or the filling in the hole is too tight, which obstructs the free expansion of the silicon carbide tube at high temperature and causes the rod to break. During installation, when the silicon carbide tube passes through the rod holes on both sides of the furnace wall, it should be freely rotated 360 degrees to prevent forced installation and beating. Before loading the rod, an iron tube with the diameter of the silicon carbide tube can be used for trial installation. The higher use temperature of silicon carbon tube is 1600, which can not be used for a long time. The normal operating temperature is 1450 degrees
1, silicon carbide pipe texture is hard and brittle, thread with limited elasticity, installation and disassembly should be fully careful attention,
