Titanium sponge 10-ton reduction-distillation furnace

Abstract

The invention relates to a combined reduction steam furnace of 10 tons of sponge titanium, which mainly consists of a U-typed reactor 1, a reaction cover 2, a furnace body 16 and a conductive device 17. The ratio of the length to the diameter of the U-typed reactor is 2.43 and the ratio of the length to the diameter of the furnace body is 1.94; the U-typed reactor is vertically arranged in the furnace body; the flange of the U-typed reactor is arranged on the furnace body and sealed by a sealing ring 8; and the upper end of the U-typed reactor is covered by the reaction cover. When a magnesium reduction method is used for producing the sponge titanium, magnesium and titanium tetrachloride carry out reduction reaction in the reactor; the produced heat is transferred into a hearth by the wall of the reactor; the plugs of an air inlet / outlet pipe 10 are opened according to the setting of the temperature; and excess heat is discharged by an air outlet pipe 9. Heat radiation realizes heat exchanging according to the convection principle of cold air and the wall of the reactor. The electric consumption is 6500KWh per ton of titanium, each ton of products reduce the electricity by more than 1500 to 2000 kilowatt hour, the argon reduces the pressurizing time by 1 to 2 hours, the productivity is improved by 90 percent and the economic effect is very obvious.

Description

technical field [0001] The invention belongs to the technical field of sponge titanium returning and steaming furnaces, in particular to a 10-ton sponge titanium combined returning-steaming furnace. Background technique [0002] The 10-ton sponge titanium combined steamer has not yet been developed in China. The main furnace types of domestic existing returning-steaming furnaces are series furnaces of 1 ton, 2 tons, 3 tons and 4 tons, and combined returning-steaming furnaces have 5 tons, 6 tons, 8 tons and 12 tons, and the power consumption is 8000-9000 degree / ton, the product density is higher. Moreover, there are only 4-ton, 5-ton, and 6-ton furnaces in China with relatively mature technology and equipment, but the product quality has been unstable, and the hard core of the titanium core is relatively obvious. [0003] The production capacity of the largest 12-ton combined return-steam furnace in China is the highest in the world, but due to the imperfect equipment and p...

Problems solved by technology

The wall-climbing pipe for magnesium chloride discharge adopts split welding, resulting in a very long weld seam, which is very easy to crack during the production process and affects the export of magnesium chloride, and also increases maintenance costs and labor intensity
