Problems solved by technology

However, most of the existing titanium infiltration processes for stainless steel reactors have the characteristics of long titanium infiltration period, poor titanium infiltration effect, high titanium infiltration cost, and high impurity elements of iron and nickel in the product, which is not conducive to the economical titanium infiltration production of stainless steel reactors for the production of sponge titanium.
In order to effectively solve the problems of poor titanium infiltration effect, low titanium infiltration efficiency and high titanium infiltration cost in stainless steel reactors, it is necessary to find a method for titanium infiltration in stainless steel reactors for sponge titanium production

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 ...

Abstract

The invention discloses a titanium infiltration method and a titanium infiltration agent for the inner wall of a sponge titanium stainless steel reactor, belonging to the technical field of design and manufacture of sponge titanium production process equipment. Provided are a titanium infiltration method and a titanium infiltration agent for the inner wall of a sponge titanium stainless steel reactor with good infiltration effect and short technological process. In the titanium infiltration method, the titanium contained in the titanium infiltration agent coated on the inner side wall of the stainless steel reactor is infiltrated into the inner side wall of the stainless steel reactor by means of distillation under high temperature and high vacuum. The titanium penetrating agent is a slurry mixture formed by mixing titanium hydride powder: distilled water: water-based glue in a ratio of 1:2:0.1.

Description

technical field [0001] The invention relates to a titanium infiltration method, in particular to a titanium infiltration method for the inner wall of a sponge titanium stainless steel reactor, and belongs to the technical field of design and manufacture of sponge titanium production process equipment. The present invention also relates to a titanium infiltration agent used in the titanium infiltration method. Background technique [0002] In the production of titanium sponge, the reactor is the core container for the production of titanium sponge. The current reactor for the production of titanium sponge has been gradually transferred from carbon steel to stainless steel. The stainless steel reactor has long service life, small deformation and maintenance efficiency. Advanced features. However, most of the existing titanium infiltration processes of stainless steel reactors have the characteristics of long titanium infiltration cycle, poor titanium infiltration effect, high...
