preparation example Construction

[0029] There is no special requirement for the preparation method of the high-temperature oxidation-resistant coating of the present invention, and various methods commonly used in the art can be used, as long as the components are mixed uniformly. However, the inventors of the present invention found in their research that the following method can be used to prepare the high temperature oxidation resistant coating, which can make the components mix more uniformly. The specific method is: under stirring, slowly add the oxidation protection agent into the water-soluble film-forming agent, when the amount of the oxidation protection agent is added in half, start to slowly add 3-5% of water, and make the oxidation protection agent and 3-5 % of water is added together, then add curing agent, stir evenly, then add dispersant, stir until the liquid is in a uniform and stable phase, then add thickener, stir evenly and then add the remaining water.

Abstract

The invention discloses a high-temperature oxidation resistant coating material. The high-temperature oxidation resistant coating material is obtained after a raw material mixture is uniformly mixed, wherein the raw material mixture contains an oxidation protecting agent, a water-soluble film forming agent and water; the oxidation protecting agent contains Al powder, Zn powder and Sn powder which are in the weight ratio of 1: (0.005-0.06): (0.003-0.04). The invention further discloses application of the high-temperature oxidation resistant coating material in titanium ingot production and a titanium ingot production method. The high-temperature oxidation resistant coating material disclosed by the invention has the advantages that the condition that the surface of a titanium ingot is not subjected to oxidation cracking under the condition that the titanium ingot is subjected to constant temperature for 8 hours at the high temperature of 1,000 DEG C can be guaranteed, and the formation of an oxygen dissolved layer can be greatly reduced; the high-temperature oxidation resistant coating material has an environmental-friendly effect; the preparation process is simple; a variety of coating manners can be adopted. The titanium ingot production method disclosed by the invention has good economic and social benefits and has relatively broad popularization and application prospects in titanium plate and titanium tube production industries.

Description

technical field [0001] The invention relates to the field of metal high-temperature-resistant coatings, in particular to a high-temperature oxidation-resistant coating, the application of the high-temperature oxidation-resistant 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 remove cracks and dissolved oxygen layers, whi...
