In the industrial production of titanium sponge, the main production process is the production by the Kroll method, and the principle is that under the protection of argon, gaseous titanium tetrachloride is added into an iron closed reactor container, so that the titanium tetrachloride and molten magnesium which is added into the reactor at one time are subjected to reduction displacement reaction to generate main product titanium foam and byproduct liquid magnesium chloride, and because the reduction reaction is exothermic reaction, a large amount of reaction heat is generated during the reduction production, the reaction heat corrodes a large cover bottom plate through thermal radiation, and impurity iron of the large cover bottom plate enters the titanium sponge product, so that the quality of the titanium sponge product is reduced. The large cover is one of main devices for preparing the titanium sponge, is mainly made of common carbon steel and stainless steel, and is not subjected to special treatment during reduction production. After the large covers of many manufacturers are manufactured, the large covers are put into use. Through production practices, when the new large cover is used in the first three furnaces, the titanium iron content of the sponge on the upper part of the titanium lump is high, the product quality is influenced, the large cover is disabled after being used for a period of time, and the production cost is increased.
