Smelting of titanium rod for sale, to go through complicated steps. Ilmenite becomes titanium tetrachloride, and then sealed into a stainless steel tank filled with argon gas , so that they react with metallic magnesium, get " titanium sponge ." This porous " sponge titanium" is not used directly , but also they must be melted into a liquid in an electric furnace to cast titanium ingots. However, the manufacture of such electric and easy! titanium grade 2 sheet Besides furnace and clean air must be pumped , the more vexing is that simply can not find a crucible containing liquid , because generally contain refractory oxides , which will be liquid oxygen away. Later, it was finally invented a " water-cooled copper crucible ," the electric stove. Only the central part of the area of this hot furnace , and the rest are cold ,medical titanium plate the titanium is melted in an electric furnace , the flow of water cooled copper crucible wall immediately cemented titanium ingots . This method has been used to produce several tons of blocks, but it costs can imagine.
