Technical field
The present invention relates to a kind of Technology for Heating Processing, particularly a kind of casting anti-deformation Technology for Heating Processing.
Background technology
Metal heat treatmet is to be placed on metal works in certain medium heat, be incubated, cooling down, by changing metal material
The institutional framework of surface or inside controls the process of its performance.Metal heat treatmet be important process in machine-building it
One, the chemical composition of the general shape for not changing workpiece of heat treatment and entirety, but change point of inside workpiece by heating
Minor structure, or change the chemical composition of workpiece surface, assign or improve the performance of workpiece.Current metal works heat treatment
It is larger to there is metal works deformation often due to technique is single in technique.
The content of the invention
It is an object of the present invention to provide a kind of metalwork anti-deformation Technology for Heating Processing.The present invention can prevent metalwork
Deformation, ensure metalwork quality.
Technical scheme：Metalwork anti-deformation Technology for Heating Processing, is comprised the following steps that：

Part, 5 parts of chromium oxide, 8 parts of cupric oxide, 2 parts of aluminum oxide, 6 parts of acrylic acid, 15 parts of polyvinyl acetate emulsion, 15 parts of ethanol solution；
(3) capable heating is injected into by laser flame, is heated to 860 DEG C of temperature, continuous heating 12 minutes；
(4) metalwork is cooled down, temperature is cooled to 120 DEG C, and cooling medium is the poly- alkylene ethylene glycol polymerization that concentration is 14%
The thing aqueous solution.
The speed of the heat temperature raising is 80 DEG C/h programming rate heating.
The present invention by accurately control heat treatment temperature, protective coating setting, change hardening media and reduce metalwork
External carbuncle, thermal stress and structural stress suffered by (casting), final indeformable, guarantee after ensureing steel-casting heat treatment and quenching
Metalwork quality.The protective layer manufacture craft of the present invention is simple, is easy to grasp, coating compactness is good, can be effectively to metalwork shape
Into protective layer, hot-working plaque is reduced, reduces oxidational losses during metalwork heat treatment, and protective layer is easy after metal heat treatmet
In coming off, there is the characteristics of efficient and easy to use.
