Problems solved by technology

These two drying methods have disadvantages:
Because the previous production process of sponge titanium will leave chlorine in the sponge titanium, chlorine will combine with water to form hydrochloric acid, which will corrode the inner wall of the drying furnace

Embodiment Construction

[0015] A method for drying titanium and titanium alloy briquettes. The feature of the invention is that the heat of the quartz tube heating element is used to dry the titanium and titanium alloy briquettes by adopting the method of heating in a closed oven.

[0016] In the present invention, all the inner walls of the heating furnace are sealed with aluminum plates, a convection fan is installed behind the heating furnace, and a row of tidal fans are installed on the top of the heating furnace; when heating, the temperature in the furnace should not exceed 120 degrees Celsius; every 30 to 40 minutes of heating Finally, turn on the exhaust fan to drain the moisture.

[0017] In the present invention, an electronic hygrometer is arranged in the heating furnace to monitor the humidity in the heating furnace chamber.

[0018] Quartz glass products use quartz glass tubes as infrared radiation sources, no coating, no pollution, no harmful radiation, excellent chemical stability, hig...

Abstract

The invention discloses a titanium and titanium alloy pressing lump material drying method. Heat of a quartz tube is adopted for drying titanium and titanium alloy pressing lump materials. According to the method, the efficiency for drying the sponge titanium pressing lump materials is improved by utilizing the far infrared characteristics of a quartz tube, meanwhile, the temperature can be controlled accurately, and the condition that the sponge titanium pressing lump materials can not be oxidized is ensured, and the component quality of titanium ingot products is improved.

Description

technical field [0001] The invention belongs to the technical field of drying methods for titanium and titanium alloy briquettes. Background technique [0002] Domestic and foreign EB furnace smelting enterprises generally use sponge titanium briquette as the raw material for the furnace. After the sponge titanium is exposed to the air for a period of time, it will absorb a certain amount of moisture. This moisture will have a negative effect on the later EB furnace smelting. The hydrogen will react violently with titanium. In order to dehydrate, we generally need to dry the sponge titanium briquette. The drying method can use gas drying furnace, electric heating tube drying furnace. These two drying methods have disadvantages: [0003] Gas drying furnace [0004] The heat source of the gas drying furnace adopts industrial gas, which contains various impurities, which is easy to pollute the titanium sponge, and the high temperature of the gas flame is easy to cause the o...
