Problems solved by technology

[0004] In the rolling process of titanium tubes, due to the deformation of titanium ingots, the effect of spraying the coating on the surface of titanium ingots to prevent steel-titanium bonding is not good
If the paint is directly sprayed on the surface of the rolling capstan, due to the different materials of the capstan and the titanium ingot, the film forming and adhesion effects are poor, and it cannot prevent steel-titanium bonding well
In addition, the use of this coating requires spraying treatment on the surface of each titanium ingot, and the coating needs a certain period of time to dry after spraying, so the preparation process becomes complicated, the preparation time is long, and continuous and efficient production is not possible.

preparation example Construction

[0031] The preparation method of the oil-based high-temperature-resistant steel-titanium isolation coating of the present invention has no special requirements, and various methods commonly used in the field can be used, as long as the components are mixed evenly, and it can be prepared immediately for use. However, the inventors of the present invention found in their research that the oily high-temperature-resistant steel-titanium isolation coating can be prepared by the following method, 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 tin powder, talcum powder, iron powder and aluminum oxide powder under stirring, then add the curing agent, stir evenly, and then add Dispersant, just stir until it becomes a uniform and stable phase.

[0039] Under normal temperature and pressure, take epoxy resin (solid content 50%) and place it in a container for use; add diluent and stir evenly for use; measure Sn powder, talcum powder, Fe powder, Al 2 o 3 powder, slowly add to the container, stirring continuously during the adding process, and stir evenly; then measure the curing agent SiO 2 powder, put it into a container, and stir evenly; then measure and add polyvinyl alcohol 200 as a dispersant, add it to the container, and stir until the solution is in a uniform and stable phase to obtain the oily high-temperature-resistant steel-titanium isolation coating of the present invention. The consumption of each raw material is shown in Table 1.

Abstract

The invention relates to oily high-temperature steel-titanium isolating paint and application thereof, and belongs to the technical field of steel-titanium anti-adhesion coatings. The oily high-temperature steel-titanium isolating paint is applied to rolling of titanium pipes. The paint comprises, by weight, 50-150 parts of oily film forming agents, 30-80 parts of tin powder, 200-300 parts of talcum powder, 30-80 parts o iron powder and 400-450 parts of aluminum oxide powder. Good isolating layers are formed after roller beds or winches of steel equipment are coated with the oily high-temperature steel-titanium isolating paint, so that titanium ingots can be prevented from being adhered to rollers or the winches of the steel equipment during rolling or punching at the temperature of 900 DEG C, product dimension accuracy and surface quality can be improved, yield and production efficiency of titanium material processing can be increased, and production cost can be reduced.

Description

technical field [0001] The invention relates to an oily high-temperature-resistant steel-titanium isolation coating and an application thereof, and belongs to the technical field of steel-titanium anti-adhesion coatings. Background technique [0002] At present, the domestic use of titanium ingot round blanks to produce titanium tubes is to directly heat the titanium ingot round billets in a heating furnace at 900 ° C for more than 4 hours, and then push out the heating furnace for high-temperature rolling of titanium tubes. Due to the high temperature, titanium and titanium alloys tend to "stick to titanium" with steel rolling equipment, roller tables and rolling winches, which makes the surface of titanium tubes appear "lack of meat" at different depths. It is rotating piercing and rolling. The titanium billet is pierced and rolled during high-speed rotation. Due to the high temperature characteristics of the titanium-based titanium alloy, it is easy to stick to iron, and ...
