Energy-saving durable efficient reduction-distillation integrated electric furnace for titanium sponge production

Abstract

The invention relates to an energy-saving durable efficient reduction distillation integrated electric furnace for titanium sponge production. The electric furnace comprises a steel electric furnace shell, a forced circulation cooling water jacket is arranged between an upper flange and a lower flange on the upper part of the furnace shell, a ring of annular boss is arranged on the upper flange, and a ring of annular groove is arranged outside the upper flange; an insulating layer is arranged on the inner wall of the furnace shell; a plurality of rows of annular air inlet channels and one or more rows of annular air outlet channels are arranged in the heat insulation layer of the upper section of the electric furnace, and a plurality of air inlets and a plurality of air outlets are uniformly arranged from the annular air inlet channels in the heat insulation layer to interior of the electric furnace along the circumference; a total air inlet pipe of the annular air inlet channels is connected with a frequency conversion fan and an exhaust chimney; a multi-zone resistance heating wire or belt respectively provided with a thermocouple temperature measuring device is arranged on the inner side of the heat insulation layer in the furnace; a plurality of inward anti-collision columns in the circumferential direction are arranged at the middle lower part of the inner circumference ofthe furnace shell of the electric furnace; and a ring of annular wind deflector is arranged on the lower edges of the annular wind outlet channels. The electric furnace has the advantages that the energy consumption is reduced, the production efficiency is improved, the service life is prolonged, the production cost is reduced, and the excellent product rate of the titanium sponge is improved.

Description

technical field [0001] The invention relates to a reduction distillation electric furnace for the production of sponge titanium, in particular to an energy-saving, durable, high-efficiency reduction distillation integrated electric furnace for the production of sponge titanium. Background technique [0002] The existing industrial production methods of sponge titanium generally adopt the Krall method, that is, the reduction of titanium tetrachloride with metal magnesium to produce sponge titanium. The production of titanium sponge by the Claure method mainly includes a reduction process and a distillation process. During the reduction process, first put the reaction vessel into the electric furnace, add a certain amount of molten metal magnesium or magnesium ingots into the reactor at one time, and heat the metal magnesium in the reactor to 800°C to 900°C through the electric furnace until it is completely melted. The titanium tetrachloride liquid is continuously added into...

AI Technical Summary

Problems solved by technology

[0003] Therefore, the electric furnace is a key equipment in the production of sponge titanium, and it is the key that directly affects the production cost and quality of sponge titanium. The existing electric furnace for sponge titanium production has high energy consumption per unit of sponge titanium, short service life of the electric furnace, and low production efficiency of sponge titanium. , high production cost, low rate of high-quality titanium sponge, etc.
