preparation example Construction

[0029] There is no special requirement for the preparation method of the oil-based high-temperature oxidation-resistant coating of the present invention, and various methods commonly used in this field 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 oil-based high-temperature oxidation-resistant coating, so that the components can be mixed more uniformly. The specific method is: first mix the oily film-forming agent with the diluent to dilute, then slowly add the oxidation protection agent under stirring, then add the curing agent, stir evenly, then add the dispersant, and stir until it becomes a uniform and stable phase.

[0030] In the second aspect, the present invention provides the application of the above-mentioned oily high temperature oxidation resistant coating in the production of titanium ingots.

[0031] In a third aspect, the pre...

Abstract

The invention discloses a high-temperature oxidation resistant oil paint. The high-temperature oxidation resistant oil paint is obtained after mixing a raw material mixture uniformly, wherein the raw material mixture contains an oxidation protective agent and oil film-forming agents; the oxidation protective agent contains Al powder, Zn powder and Sn powder in a weight ratio of 1 to (0.005-0.06) to (0.003-0.04). The invention also discloses an application of the high-temperature oxidation resistant oil paint to titanium ingot production and a production method of titanium ingots. The high-temperature oxidation resistant oil paint can ensure that the surfaces of the titanium ingots are not oxidized to crack at a constant high temperature of 1000 DEG C for 8 hours, can greatly reduce formation of dissolved oxygen layers, has the environmental effects, is simple in preparation process and can adopt various coating modes. The production method of titanium ingots has good economic and social benefits and has wider popularization and application prospects in the titanium plate and titanium pipe production industry.

Description

technical field [0001] The invention relates to the field of metal high-temperature-resistant coatings, in particular to an oily high-temperature oxidation-resistant coating, the application of the oily 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 ...
