Energy-saving and durable high-efficiency reduction and distillation integrated electric furnace for the production of sponge titanium

Abstract

The invention relates to an energy-saving, durable, high-efficiency reduction and distillation integrated electric furnace for the production of sponge titanium. A circle of annular bosses and a circle of annular grooves are set on the outside; an insulation layer is provided on the inner wall of the furnace shell; multiple rows of annular air inlet ducts and one or more rows of annular air outlet channels are arranged in the insulation layer of the upper section of the electric furnace. Multiple air inlets and multiple air outlets are evenly arranged along the circumference from the annular air inlet duct to the electric furnace; the total air inlet pipe of the annular air inlet duct is connected to the frequency conversion fan and the exhaust chimney; the inner side of the furnace insulation layer is respectively equipped with thermocouples The multi-zone resistance heating wire or belt of the temperature measuring device; a plurality of inward anti-collision columns in the circumferential direction are arranged in the middle and lower part of the inner circumference of the electric furnace shell; It has the advantages of reducing energy consumption, improving production efficiency, prolonging life, reducing high production costs, and increasing the rate of high-quality sponge titanium.

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.
