Description
Technical Field
The utility model relates to a preparation of titanium sponge production, in particular to a device of big lid titanizing in titanium sponge production.
Background
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.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that in the titanium sponge reduction production process, because the reaction heat corrodes the big bottom plate of the cover through the heat radiation, the big bottom plate of the cover impurity iron enters into the titanium sponge product, leads to the quality reduction of the titanium sponge product.
In order to solve the technical problem, the technical scheme of the utility model as follows:
a large cover titanizing device in titanium sponge production comprises a heating furnace, a reactor and a large cover; the large cover is arranged on the reactor, the reactor is connected with the large cover through a bolt, and a sealing rubber gasket is arranged between the reactor and the large cover; the device also comprises an evacuation pipe arranged on the large cover, one end of the evacuation pipe is connected with the vacuum pipe, one end of the vacuum pipe is connected with an evacuation system, the reactor is provided with a hoisting structure, the bottom of the large cover is provided with a large cover bottom plate, the heating furnace is provided with a heating control element, and the evacuation system is connected with a computer.
Adopt above-mentioned technical scheme's beneficial effect:
1. the utility model discloses a titanium infiltration of big lid bottom plate before reduction production.
2. The utility model discloses reduced big lid bottom plate impurity iron and mixed into the product, control impurity iron content influences the product grade, improves product percent of pass and grade rate, and the percent of pass improves 1 percentage point than prior art.
