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 oily insulating steel-titanium 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 have found in their research that the following method is used to prepare the oily insulating steel-titanium 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 copper powder, ferric oxide powder, iron powder and aluminum oxide powder under stirring, then add the curing agent and stir evenly , then add the dispersant, and stir until a uniform and stable phase is formed.

[0032] The oily insulating steel-titanium coating of the present invention can be used in high-temperature rolled titanium pipes.

[0033]Before the titanium tube is rolled, th...

[0039] Under normal temperature and pressure, weigh epoxy resin (solid content 50%) and place it in a container for use; add diluent and stir evenly for use; measure Cu powder, Fe powder, Fe powder 2 o 3 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 the container, and stir evenly; then measure and add polyvinyl alcohol 200 as a dispersant, add it into the container, and stir until the solution is in a uniform and stable phase, and the oily insulating steel-titanium coating of the present invention is obtained. The consumption of each raw material is shown in Table 1.

Abstract

The invention relates to an oil-based steel-titanium barrier paint and application thereof, belonging to the technical field of steel-titanium antisticking coatings. The invention aims to provide an oil-based steel-titanium barrier paint used in titanium tube rolling. The paint comprises the following components in parts by weight: 50-150 parts of oil-based film former, 0-50 parts of copper powder, 300-350 parts of ferric oxide powder, 0-50 parts of iron powder and 400-450 parts of aluminum oxide powder. The oil-based steel-titanium barrier paint can be applied to steel equipment, roller ways and winches to form a favorable barrier layer, and can prevent the titanium ingot from binding reaction with the steel equipment rollers or winches in the 900-DEG C rolling or perforating process, thereby enhancing the dimensional precision and surface quality of the product, increasing the titanium processing yield and production efficiency and lowering the production cost.

Description

technical field [0001] The invention relates to an oily isolation steel-titanium coating and its application, 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 even form a TiFe phase. If the Ti...
