A semi-integrated i-type furnace to produce the reaction tank cover for titanium sponge

Abstract

The invention relates to the technical field of non-ferrous metal metallurgy, in particular to a reaction tank cover used for half-combined I type furnace titanium sponge production. The reaction tank cover comprises a reaction tank cover body and a sealed magnesium plate and further comprises a distillation passage barrel, the bottom of the distillation passage barrel is detachably connected with a nozzle of the reaction tank cover body in a sealed mode, the top of the distillation passage barrel is connected with the sealed magnesium plate in a sealed mode, a feeding pipe is connected to the wall of the distillation passage barrel, and a stop valve is installed on the feeding pipe. Because the distillation passage barrel and the feeding pipe structure special for feeding are arranged, it can be avoided that in the feeding process, the sealed magnesium plate is opened, so that titanium sponge suffers air pollution, the quality of the titanium sponge is obviously improved, and particularly, the content of oxygen and nitrogen will be effectively controlled; the step of feeding through detaching the sealed magnesium plate is omitted, and the labor intensity of a worker is lowered when transferring to the distillation process.

Description

technical field [0001] The invention belongs to the technical field of nonferrous metal smelting, and in particular relates to a reaction tank cover for producing sponge titanium in a semi-integrated I-type furnace. Background technique [0002] In the production process of sponge titanium in the semi-combined type I furnace, the reduction tank after the reduction and feeding will be converted to distillation. During the transdistillation operation, it is necessary to remove the feeding tube at the lid of the reaction tank, and quickly install a sealing magnesium plate at the lid of the reaction tank. After the feeding tube is removed, the titanium sponge in the reaction tank will be exposed to the air for a period of time, which eventually leads to the titanium sponge being polluted by air. In addition, the magnesium plate is fixed on the lid of the reaction tank by a metal wedge, so its sealing effect on the titanium tank is poor, and the installation quality of the magne...

AI Technical Summary

Problems solved by technology

After the feeding tube is removed, the titanium sponge in the reaction tank will be exposed to the air for a period of time, which eventually leads to the titanium sponge being polluted by the air.

In addition, the magnesium plate is fixed on the lid of the reaction tank by a metal wedge, so its sealing effect on the titanium tank is poor, and the installation quality of the magnesium plate is difficult to guarantee

During the distillation operation, the temperature of the reaction tank cover and the feeding pipe is high, and the labor intensity of the workers for the distillation is relatively high.
