Titanium and titanium alloy low-cost continuous casting technology and equipment

The invention relates to a titanium and titanium alloy low-cost continuous casting technology and equipment. Under argon protecting or inert gas atmosphere, a plasma gun of at least 65 KW is used as a heat source. Through a crystallizer, a plasma gun and a down-pulling mechanism, continuous casting of titanium and titanium alloy circular and flat cast ingots is achieved. The machining cost of titanium alloy is lowered by about at least 15%. The produced titanium and titanium alloy are even in components, segregation is avoided, and metallurgical quality problems are avoided.
