Reducing device for producing titanium sponge

Abstract

A reducing device for producing titanium sponge is mainly composed of a reactor, a reactor cover and the like, wherein a circulating pump is arranged on the reactor cover; a feed pipe penetrates through the reactor cover and is inserted into a melt magnesium chloride zone at the lower part of the reactor, while a discharge pipe penetrates through the reactor and is inserted into the upper part of the reaction zone of the reactor; and the lower end of the feed pipe is an open structure. The device realizes thermal cycle inside the reactor and is capable of effectively shortening the reduction cycle and reducing energy consumption.

Description

technical field [0001] The invention belongs to the technical field of sponge titanium production, in particular to a reducing device for producing sponge titanium by a magnesium reduction method. Background technique [0002] At present, the industrial production of sponge titanium both at home and abroad adopts the method of reducing titanium tetrachloride with magnesium. In order to reduce production costs, all countries regard large-scale equipment as the direction of technological development. However, with the increase of the furnace type, the central part of the reactor does not dissipate heat in time during the reduction period, that is, the temperature of the central part is too high, resulting in the sintering of the product in the central part and the sandwiched MgCl 2 Too much, the amount of hard blocks increases, and the product structure is dense, which seriously affects the qualified rate of the product and increases the production cost of titanium sponge.

Problems solved by technology

However, with the increase of the furnace type, the central part of the reactor does not dissipate heat in time during the reduction period, that is, the temperature of the central part is too high, resulting in the sintering of the product in the central part and the sandwiched MgCl 2 Too much, the amount of hard blocks increases, and the product structure is dense, which seriously affects the pass rate of the product and increases the production cost of sponge titanium

Due to the limitations of process conditions and equipment materials, the heat dissipation capacity of the reduction reaction zone of the reactor is insufficient, the material rate added during the reduction of sponge titanium is not large, and the reduction time is long. In addition, in order to maintain the molten state of magnesium chloride at the bottom of the reactor, it is necessary to Frequent power transmission and heat supply in the lower part of the reactor will increase the energy consumption of sponge titanium production
