[0021] The invention relates to a method for infiltrating titanium into a stainless steel reactor for producing sponge titanium. The method includes the following steps: 1) cleaning the inner wall of the reactor, so as to avoid bringing in foreign matter. Step 2) The preparation of the titanizing agent can improve the adhesion of the titanizing agent and improve the titanizing effect. Step 3) Spraying the titanizing agent can improve the uniformity of the titanizing layer. Step 4) Reactor assembly, which can improve the airtightness of the reactor. Step 5) Putting the reactor into the furnace can increase the success rate of titanium infiltration in the reactor. Step 6) Titanium infiltration in the reactor can ensure the effect of titanium infiltration in the reactor. Step 7) The reactor is cooled, which can effectively protect the titanized layer. Step 8) The qualification determination of the reactor titanium infiltration can prevent unqualified titanium infiltration rea...
Embodiment 1
[0032] The titanizing method adopted in the present invention comprises the following steps, step 1) cleaning the inner wall of the reactor, step 2) preparing the titanizing agent, step 3) spraying the titanizing agent, step 4) assembling the reactor, step 5) putting the reactor into the furnace, Step 6) titanizing the reactor, step 7) cooling the reactor, and step 8) judging whether the titanizing reactor is qualified.
[0033] The specific features are:
[0034] Step 1) cleaning the inner wall of the reactor. Spray wash the inner wall of the reactor with hydrochloric acid with a concentration of 30%. After pickling, clean the reactor with clean water. After washing with water, clean the inside of the reactor with dry compressed air. The standard is that there is no water drop on the reactor wall;
[0035] Step 2) Preparation of titanium infiltration agent. Titanium hydride powder, distilled water, and water-based glue are mixed in a ratio of 1:2:0.1 to form a slurry, which...
