Description
Technical field
The utility model belongs to magnesium refining production technical field, and particularly flux-refining method is produced the airtight a refining unit of magnesium.
Background technology
The industrial production Titanium Sponge 40-60 mesh all adopts magnesium method (Kroll method) at present, and titanium tetrachloride and MAGNESIUM METAL 99 generation reduction reaction generate Titanium Sponge 40-60 mesh and magnesium chloride.For making the magnesium chloride recycle of reduction by-product,, obtain electrolysis crude magnesium and chlorine with carrying out fused salt electrolysis in the magnesium chloride adding electrolyzer of two-maing ladle with the reduction discharging.The crude magnesium of electrolytic process output contains many impurity, must carry out refining and make quality reach the raw material that could be used as the reduction titanium tetrachloride after the requirement.
Whole process magnesium method titanium sponge manufacturing enterprise generally adopts the crude magnesium of flux method refining electrolysis output; The electrolysis crude magnesium is put into the refining copple through preheating after sucking with vacuum ladle; After stirring refining, heating up, leave standstill, obtain smart magnesium, deliver to the raw material of reduction operation after smart magnesium being sucked in the refining copple with vacuum ladle then as the reduction titanium tetrachloride.The uneven situation of titanium magnesium unavoidably appears in the production; The smart magnesium amount of refining electrolysis crude magnesium gained can not satisfy goes back steaming process and adds magnesium amount demand; Need fusing refined solid magnesium ingot to replenish, and than refining electrolysis crude magnesium, the refined solid magnesium ingot has increased melting process.
The equipment that the flux-refining method is produced magnesium adopts crucible oven more, puts big lid on crucible is furnished with.For a long time, in the crucible oven refining process, will add magnesium (electrolysis crude magnesium and solid magnesium ingot), spread ground flux, refining, take out operation such as magnesium covering greatly, big lid has bigger hole; Be in uncovered state in the production process, and crucible and big lid do not carry out any sealing yet, whole production belongs to the opened type refining; So be difficult to avoid in fusing (when adding the solid magnesium ingot), refining, the process air such as leave standstill and get in the crucible and to melt magnesium with high temperature and contact and react; The oxidizing fire of magnesium is serious, and the product quantity of slag is more, and the magnesium globule of carrying secretly with slag is also many; Cause the chemical loss and the mechanical loss of magnesium serious, the smart magnesium recovery is low; Owing to big lid is uncovered, heat scatters and disappears big in the heat-processed, and heat-up time, increase, particularly melting solid magnesium ingot time were longer, caused power consumption higher, and the production cycle prolongs; Need in the process magnesium combustion phenomena is spread the ground flux destruction, the flux consumption is big; Because it is many to produce the quantity of slag, for guaranteeing to add magnesia amount, to have to shorten and slag tap the cycle, plant factor is lower, and worker's labour intensity is big; Cover uncovered certain potential safety hazard that also exists greatly.
At present domestic production in the flux-refining method do not seen relevant airtight purified report aspect the magnesium as yet.
The utility model content
The purpose of the utility model is in order to solve the problem of the uncovered existence of flux method refined magnesium device, the airtight a refining unit that provides a kind of flux-refining method to produce magnesium, with argon gas as shielding gas; To improve the smart magnesium recovery; Shorten solid magnesium ingot fusing time, reduce power consumption, reduce stove and produce the quantity of slag; Prolong and slag tap the cycle, reduce the security risk of worker's labour intensity and production process.
For achieving the above object, the airtight a refining unit of a kind of flux-refining method production magnesium of the utility model is made up of crucible and big lid thereof, on the crucible ring flange, has the deep gouge of placing sealing member, and crucible is connected through flange with big the lid; Cover portion's different positions greatly and be provided with and add the magnesium handle hole, take out magnesium handle hole, argon-filled tube, piezometric tube, big lid bottom is provided with thermal insulation layer; Adding magnesium handle hole cover plate and be provided with eduction pipe and vision slit, is big plug with what take out that the magnesium handle hole carries out that flange is connected, and big plug is provided with little plug.
The usefulness of the utility model is: (1) avoid in fusing (when adding the solid magnesium ingot), refining, leave standstill etc. that molten magnesium contacts the generation oxidizing fire in the process with air; Reduce the magnesium loss amount; The smart magnesium recovery is greatly improved, exceed about 5 percentage points than the opened type refining; (2) because heat is lost little, solid magnesium ingot fusing time shortens about 5h, has practiced thrift power consumption greatly; (3) reduce stove and produce the quantity of slag, the cycle stretch-out of slagging tap is 5 times of original a refining unit, has increased the equipment effective rate of utilization; (4) flux only consumes when refining to some extent in the production process; And the opened type a refining unit consumes during except that refining the flux; In processes such as magnesium ingot fusing, to spread the ground flux destruction to the magnesium burning that is difficult to avoid; Thereby the flux amount that airtight refining consumes is less, also reduces worker's labour intensity simultaneously; (5) security in the increase operating process.
