[0020] The invention relates to a titanium infiltration method for a stainless steel reactor used for the production of sponge titanium. Including the following steps 1) cleaning the inner wall of the reactor, which can avoid the introduction of impurities. Step 2) The preparation of the titanium infiltration agent can improve the adhesion of the titanium infiltration agent and improve the effect of titanium infiltration. Step 3) Spraying the titanium infiltration agent can improve the uniformity of the titanium infiltration layer. Step 4) Reactor assembly can improve the air tightness of the reactor. Step 5) The reactor is put into the furnace, which can improve the success rate of titanium infiltration of the reactor. Step 6) The titanium infiltration of the reactor can ensure the effect of titanium infiltration of the reactor. Step 7) Cooling the reactor can effectively protect the titanium infiltration layer. Step 8) The qualified judgment of the reactor for titanium i...
Embodiment 1
[0031] The titanium infiltration method adopted in the present invention comprises the following steps: step 1) cleaning the inner wall of the reactor, step 2) preparing the titanium infiltration agent, step 3) spraying the titanium infiltration agent, step 4) assembling the reactor, step 5) loading the reactor into the furnace, Step 6) reactor titanium infiltration, step 7) reactor cooling, step 8) reactor titanium infiltration qualified judgment.
[0032] The specific features are:
[0033] Step 1) Cleaning the inner wall of the reactor. The inner wall of the reactor was spray-washed with hydrochloric acid with a concentration of 30%. After pickling, the reactor was cleaned with clean water. After washing with water, the inside of the reactor was purged with dry compressed air. The standard was that the reactor wall was free of water droplets;
[0034] Step 2) Preparation of titanium infiltration agent. Titanium hydride powder, distilled water, and water-based glue should ...
