Description
Technical Field
The utility model relates to a metallurgical industry especially relates to a composite crucible.
Background
The vanadium-nitrogen alloy is used as an additive for steel production, and can obviously improve the comprehensive properties of steel, such as toughness, ductility, thermal fatigue resistance and the like. With the improvement of the requirements on the steel performance in the market, the addition amount of the vanadium-nitrogen alloy is gradually increased during the production of steel. And the quality of the performance of the flaky vanadium pentoxide (flaky vanadium for short) which is used as a production raw material of the vanadium-nitrogen alloy directly determines the production quality of the vanadium-nitrogen alloy. At present, when the sheet vanadium is prepared by adopting a push plate furnace one-step method, a crucible is required to be used as a container for containing molten vanadium pentoxide. If a crucible made of stainless steel or silicon carbide is adopted in the vanadium pentoxide smelting process, the contact position of the crucible made of stainless steel or silicon carbide and the vanadium pentoxide can generate the adhesion phenomenon, because iron element in the stainless steel shows certain reducibility at high temperature and can react with the vanadium pentoxide to generate iron oxide, so that the purity of vanadium pentoxide is influenced; the crucible made of silicon carbide also has an adhesion phenomenon, because vanadium pentoxide is used as a pore filling agent to fill pores among silicon carbide particles, the adhesion between the vanadium pentoxide and the crucible made of silicon carbide is caused, and further, vanadium in the crucible cannot be poured out in time, so that the production continuity is seriously influenced; when the crucible made of the zircon quartz material is adopted, although the adhesion phenomenon does not exist between the vanadium pentoxide and the crucible, the crucible made of the zircon quartz material is high in cost and low in strength, the crucible is very easy to damage in the process of taking the vanadium sheet in the overturning mode, the service life of the crucible is seriously influenced, and the crucible is not suitable for the process of producing the vanadium sheet in batches for a long time. Therefore, the selection of the crucible has become a key bottleneck problem for the mass production of the vanadium flake.
