Dashiqiao Kailong Casting equipment plant
Implementation of standards:HB-5407-88
Description: isostatic pressing crucible smelting industry is emerging in recent years smelting tools, as ancillary products, widely used in vacuum and non-vacuum induction furnace, crucible appears to solve the high-temperature refractory alloy melting tool in the smelting process easy to sneak impurities and other problems, has been widely promoted. I plant the isostatic pressing crucible material diversification, the volume model series in the market have considerable coverage. I plant the production of corundum crucible is still a national initiative, its performance is higher than the magnesium oxide and other materials crucible, has gradually been recognized by the majority of users.
