Abstract

The invention discloses an aqueous titanium ingot high-temperature-resistant oxygen-absorbing coating material. The coating material is prepared by uniformly mixing a raw material mixture. The raw material mixture comprises an oxidation protective agent, an aqueous film-forming agent and water. The oxidation protective agent comprises Al powder, Zn powder, Fe powder and Cu powder, with the weight ration of the Al powder, the Zn powder, the Fe powder and the Cu powder being 1: 0.01-0.1: 0.01-0.1: 0.01-0.1. The invention also discloses applications of the coating material in titanium ingot production and a production method of a titanium ingot. The coating material can guarantee that the surface of the titanium ingot is not oxidized or cracked after the titanium ingot is put at a constant temperature of 1000 DEG C for 8 h. The coating material can largely reduce the formation of oxygen dissolved layers, and has an effect of environment protection. The coating material is simple in preparation process, and can adopt a plurality of coating manners. The production method has a wide popularization and application prospect in the production industry of titanium plates and titanium tubes.

Description

technical field [0001] The present invention relates to the field of metal high-temperature-resistant coatings, in particular to a water-based high-temperature-resistant oxygen-absorbing coating for titanium ingots, the application of the water-based high-temperature-resistant oxygen-absorbing 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 tita...
