preparation example Construction

[0028] There is no special requirement for the preparation method of the oil-based high-temperature-resistant protective 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 is used to prepare the oil-based high-temperature-resistant protective coating, which can make the components mix 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 a uniform and stable phase is obtained.

[0029] In the second aspect, the present invention provides the application of the above-mentioned oily high temperature resistant protective coating in the production of titanium ingots.

[0030] In a third aspect, the prese...

Abstract

The invention discloses an oily high-temperature resistant protective coating material. The oily high-temperature resistant protective coating material is obtained after a raw material mixture is uniformly mixed, wherein the raw material mixture contains an oxidation protecting agent and an oily film forming agent; the oxidation protecting agent contains Al powder and Fe powder which are in the weight ratio of 1: (0.01-0.1). The invention further discloses an application of the oily high-temperature resistant protective coating material in titanium ingot production and a titanium ingot production method. The oily high-temperature resistant protective 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 undergoes constant temperature for 8 hours at the high temperature of 1,000 DEG C can be guaranteed, the forming possibility of an oxygen dissolved layer can be greatly reduced, and the yield and production efficiency of a titanium material are increased; the construction environment is not affected; the preparation process is simple; a variety of coating manners, such as pneumatic spraying, vacuum spraying and brushing, 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 an oily high-temperature-resistant protective coating, the application of the oily high-temperature-resistant protective coating in the production of titanium ingots, and a production method of 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...
