Abstract

The invention discloses a heat-resisting oxygen coating for an oily titanium ingot. The heat-resisting oxygen coating for the oily titanium ingot is obtained by a raw material mixture in an evenly mixing manner, wherein the raw material mixture contains an oxidation protecting agent and an oily film-forming agent; the oxidation protecting agent contains Al powder, Zn powder, Fe powder and Cu powder; the mass ratio of the Al powder to the Zn powder to the Fe powder to the Cu powder is 1:(0.01-0.1):(0.01-0.1):(0.01-0.1). The invention also discloses application of the heat-resisting oxygen coating for the oily titanium ingot in titanium ingot production, and a production method of the titanium ingot. The heat-resisting oxygen coating for the oily titanium ingot can prevent the surface of the titanium ingot from being oxidized to crack at the at constant temperature of 1,000 DEG C for 8 hours, formation of a dissolved oxygen layer can be greatly reduced, the heat-resisting oxygen coating has the environmental protection efficacy and simple preparation process, and can adopt a plurality of coating modes. The production method of the titanium ingot disclosed by the invention has broad popularization and application prospects in titanium plate and titanium tube production.

Description

technical field [0001] The present invention relates to the field of metal high-temperature-resistant coatings, in particular to an oily titanium ingot high-temperature oxygen-absorbing coating, the application of the oily titanium ingot high-temperature oxygen-absorbing coating 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 rolling process to r...
