Oily High Temperature Resistant Titanium-Steel Bonding Coating and Its Application

Abstract

The invention relates to an oily high-temperature-resisting titanium-steel bonding prevention coating and application thereof, belongs to the technical field of titanium-steel bonding prevention coatings and aims at providing an oily high-temperature-resisting titanium-steel bonding prevention coating used in titanium tube rolling. The coating is prepared from, by weight, 50-150 parts of an oily film-forming agent, 0-50 parts of zinc powder, 100-150 parts of talcum powder, 200-300 parts of ferric oxide powder and 400-450 parts of aluminum oxide powder. The oily high-temperature-resisting titanium-steel bonding prevention coating is applied to a steel and iron device, a roller or a winch to form a very good isolation layer and can ensure that titanium ingots do not produce bonding reaction with the steel and iron device, the roller or the winch in the 900 DEG C rolling or perforation process, improve the size precision and surface quality of products, improve the machining yield and production efficiency of titanium materials and reduce the production costs.

Description

technical field [0001] The invention relates to an oily high temperature resistant anti-titanium-steel bonding coating and an application thereof, belonging to the technical field of titanium-steel anti-bonding 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 ...

AI Technical Summary

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 titanium-steel 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 titanium-steel 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.
