High-temperature-resistance oxidation coating for predry-free full-descaling steel billet

Abstract

The invention discloses total scale removal billet using high temperature resistance oxidation paint without pre-drying. It includes the following steps: using high temperature melt film screen and oxidation reduction doubling protection mechanism, cross blend modified resin ofmetlbond, epoxy, organic silicon resin, high temperature oxide, high melting point reducing metal, flame resisting silicate material, auxiliary agent as raw material, processing complexing, cross linking, curing, drying. The using of the paint is not need billet surface pretreatment, pre-drying, has self stripping total scale removal performance, can reduce billet ratio of burnt area, effectively increase steel surface quality, reduce steel surface post processing workload, has no pollution for environment. And it can be used in heating furnace, heat treatment furnace under 1500 degree centigrade etc.

Description

technical field [0001] The invention relates to the technical field of heating anti-oxidation protective coatings, in particular to a heating anti-oxidation protective coating capable of completely removing oxidation scales on the surface of steel substrates without pre-drying. Background technique [0002] During the heating process of the steel billet before rolling, the surface of the billet undergoes a violent oxidation reaction at high temperature, resulting in oxidation and burning, which reduces the yield of the steel. It is also difficult to remove it with a hammer, which increases the workload and production cost of the post-process surface treatment, and affects the surface quality of the product. It is a technical problem that plagues enterprises. In recent years, relevant enterprises and institutions at home and abroad have actively carried out the research and development of high-temperature protective coatings for steel products, but so far, these various coati...

Problems solved by technology

[0002] During the heating process of the steel billet before rolling, the surface of the billet undergoes a violent oxidation reaction at high temperature, resulting in oxidation and burning, which reduces the yield of the steel. It is also difficult to get rid of it with a hammer, which increases the workload and production cost of the post-process surface treatment, and affects the surface quality of the product. It is a technical problem that plagues enterprises.

In recent years, relevant enterprises and institutions at home and abroad have actively carried out the research and development of high-temperature protective coatings for steel products, but so far, these various coatings still have the following deficiencies: 1. The coating of the coating must be pre-dried (naturally dried or baked) during use. dry), so that the original process must be greatly changed, and the investment in coating and drying facilities is large, which limits the convenient use of coatings on continuous industrial production lines; 2. The metal oxide scales on the surface of special steel billets cannot be completely removed
