Abstract
The invention discloses decarbonization preventing paint for a workpiece. The decarbonization preventing paint consists of Na2O.SiO2, Al2O3, Cr2O3, SiC, poly-internal-olefin and graphite powder. According to the decarbonization preventing paint, common industrial raw materials are reasonably mixed, so that oxidation and decarbonization during thermal treatment is greatly reduced; after the workpiece is heated, the paint can be automatically peeled off from the surface of a basal body; and the paint is low in price, and has a good application prospect.
Description
Technical field
The present invention relates to metal heating processing technology field of material technology, particularly relate to the anti-decarburizing coating of a kind of workpiece.
Background technology
In iron and steel heat treatment process, the harm of oxidation and decarburization is very serious, and it makes steel material surface form zone of oxidation, causes the waste of material, increases machining operations amount, and due to the loss of carbon, makes the every mechanical property reduction of steel.Coating protection method has less investment, does not need the features such as complex apparatus, working method are simple, cost is low, adaptability is stronger, applies when being particularly suitable for medium and small sized enterprises' thermal treatment.But automatic spalling resistance when current coating protecting performance and cooling needs to improve.
Summary of the invention
Object of the present invention is exactly defect for above-mentioned existence and provides a kind of workpiece anti-decarburizing coating.The present invention adopts conventional industrial raw material to carry out rational allocation, oxidation and decarbonization during thermal treatment significantly can be reduced, and after workpiece heat, coating can peel off voluntarily from matrix surface, and coating price is cheap simultaneously, has good application prospect.
The anti-decarburizing coating technical scheme of a kind of workpiece of the present invention is that this coating is by Na

Adopt coating of the present invention to carry out workpiece protection, be incorporated to stove and be heated to austenitizing, quenching of coming out of the stove after insulation terminates, the workpiece surface after quenching is sparkling clean, protected non-oxidation, decarburization phenomenon.
A kind of workpiece of the present invention anti-decarburizing coating beneficial effect is: coating material preparation technology of the present invention is simple, screening characteristics is good, oxidation and decarbonization during thermal treatment is significantly reduced, the process redundancy needing heat treated part can be reduced, thus, the non-oxidation decarburization thermal treatment of workpiece can be realized, and after workpiece heat, coating can peel off voluntarily from matrix surface, thus de-scaling operation when decreasing rolling, do not affect steel rolling precision; Coating price is cheap simultaneously, therefore has good application prospect.
