Abstract

The invention discloses an aqueous titanium ingot high temperature oxidation resistant paint prepared by evenly mixing a raw material mixture, the raw material mixture contains an oxidation protective agent, a water soluble film-forming agent and water; the oxidation protective agent contains Al powder, Zn powder, Sn powder and Cu powder, the weight ratio of Al powder to Zn powder to Sn powder to Cu powder is 1:0.01-0.1:0.01-0.1:0.01-0.1. The invention also discloses the application of the aqueous titanium ingot high temperature oxidation resistant paint in titanium ingot production and a titanium ingot production method. The aqueous titanium ingot high temperature oxidation resistant paint can guarantee that titanium ingot surface cannot be oxidized to crack at a constant high temperature of 1000 DEG C for 8h, can greatly reduce the formation of a dissolved oxygen layer, has the environmental protection function, and is simple in the preparation process, and a variety of coating methods can be used. The titanium ingot production method has broad popularization and application prospects in titanium plate and titanium tube production.

Description

technical field [0001] The invention relates to the field of metal high-temperature-resistant coatings, in particular to a water-based high-temperature oxidation-resistant coating for titanium ingots, the application of the water-based high-temperature oxidation-resistant coating for titanium ingots in the production of titanium ingots, and a production method for titanium ingots. Background technique [0002] Titanium ingots generally undergo annealing treatment during the production process. Annealing is generally carried out at a high temperature of about 900°C. At high temperatures, oxygen will enter the surface of the titanium ingot to form a hard dissolved oxygen layer. The titanium ingot is heated at 900°C for 4 hours. Deep cracks with a depth of about 20mm will appear on the above surface. In order to ensure the subsequent rolling of titanium tubes and the surface quality of hot-rolled titanium plates, it is necessary to cut and grind the titanium ingots during the r...
