Embodiment Construction

[0021] The invention provides a continuous rolling technology of titanium and titanium alloys, comprising the following steps:

[0022] a. Feeding: transport the titanium or titanium alloy ingot to the discharge track in the induction heating furnace;

[0023] b. Heating: When the titanium or titanium alloy ingot is transported to the discharge track in the induction heating furnace, the titanium or titanium alloy ingot is heated by electromagnetic induction by energizing the induction heating furnace;

[0024] c. Insulation conveying: transporting the heated pure titanium or titanium alloy ingot in step a from the induction heating furnace to the rolling mill in the state of insulation;

[0025] d. Rolling: use a rolling mill to continuously roll the pure titanium or titanium alloy ingots that are transported in with heat preservation in step b;

[0026] e. Material discharge: The material that has been rolled continuously is transported from the rolling unit to the charging...

Abstract

The invention relates to a titanium and titanium alloy low-cost continuous rolling 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 an induction heating furnace, a rolling unit and a guiding wheel component, continuous casting and continuous rolling of titanium and titanium alloy circular and flat cast ingots are achieved. The machining cost of titanium alloy is lowered by about at least 30%. The produced titanium and titanium alloy are even in components, segregation is avoided, metallurgical quality problems are avoided, and the performance of plates and rods obtained by a traditional machining mode and conventional mechanical property are equal.

Description

technical field [0001] The patent of the invention relates to a technology and equipment for low-cost continuous rolling of titanium and titanium alloys, belonging to the field of metal material preparation and processing. Background technique [0002] Due to their high specific strength, corrosion resistance, high temperature resistance, and non-magnetic properties, titanium and titanium alloys are widely used as structural materials and functional materials in the fields of national defense technology industry and civilian industrial technology. However, due to the high cost of preparation and processing of titanium and titanium alloy materials, they cannot be widely used like steel and aluminum. The reason for the high manufacturing cost of titanium and titanium alloys is that in addition to raw materials, the most important thing is the high cost of preparation and processing, which accounts for about 60% of the entire preparation cost of titanium and titanium alloys. At...
