Abstract
The invention provides a carbon steel treatment method to overcome restriction of traditional single carbon steel surface treatment modes. Pickling passivation and paint spraying treatment enhance the corrosion resistance of a carbon steel material, and poor weatherability and corrosion acceleration generated after paint film shedding severely influence the quality and the service life of products, so the appearance class is reduced. The surface of carbon steel is polished, so the defects of the corrosion layer of a base material are eliminated, and the appearance of the carbon steel is uniform and consistent; pickling is adopted to remove rust points; galvanizing treatment is adopted to enhance the weatherability and the corrosion resistance of the carbon steel and improve the adhesion and the appearance effect of an electrophoresis paint; grinding and sandblasting treatments are carried out after galvanizing; and electrophoresis and constant temperature baking treatment are finally carried out. The method improves the corrosion resistance and the weatherability of a carbon steel piece, and realizes delicate appearance effects.
Description
Technical field
The present invention relates to field of metal surface treatment technology, particularly relate to a kind of steel surface treatment process.
Prior art
At present, increasingly extensive along with carbon steel product especially outdoor use carbon steel product application, the single surface treatment modes of some tradition cannot meet outdoor erosion resistance requirement comprehensively.Although the carbon steel material after such as acid wash passivation, process of spraying paint enhances its rotproofness, its weathering resistance, the accelerated corrosion produced after pull-away, have a strong impact on quality and the work-ing life of product, reduced its outward appearance class.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of steel surface treatment process, can overcome the segmental defect of existing single carbon steel treatment process, improves work-ing life, improves outward appearance class.In order to solve the problems of the technologies described above, the invention provides a kind of steel surface treatment process, the method comprising the steps of:
1) rubbing down process is carried out to pending steel surface;
2) pickling, pot galvanize process are carried out to the steel surface after rubbing down process;
3) reconditioning, sandblasting are carried out to the steel surface after pot galvanize process;
4) the steel surface phosphatization after sandblasting being completed, electrophoretic process;
5) to the steel surface constant temperature baking processing after phosphatization, electrophoresis.
Rubbing down process steel surface is adopted in technique scheme, eliminate base material corrosion layer defect and make its appearance uniform consistent, pickling is adopted to remove rust spot, pot galvanize process is adopted to strengthen its weathering resistance, erosion resistance, for improving electrocoating paint sticking power and appearance effect, reconditioning, sandblasting is carried out, final electrophoresis, constant temperature baking processing after pot galvanize.
Embodiment
Below in conjunction with embodiment, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.Present method comprises step: 1) rubbing down process, effectively can remove the corrosion layer on carbon steel work-piece surface, make the roughness that the surface of carbon steel work-piece reaches certain, reduces carbon steel work-piece substrate surface defect, makes its homogenizing.2) pickling, pot galvanize process, remove the rust spot of steel surface, add weathering resistance and the erosion resistance of carbon-steel parts.3) reconditioning, sandblasting, after pot galvanize, workpiece surface has and necessarily determines, reconditioning is carried out to defective locations, adopt the mode of high-velocity jet glass sand that the appearance of outer surface of workpiece is changed to steel surface after reconditioning, because glass sand is to the impact of workpiece surface and shear action, workpiece surface is made to obtain the roughness of higher degree of cleaning and Geng Gao, sticking power after the mechanicalness of workpiece surface and electrophoresis can be improved, therefore improve the sticking power that layer moulded by the fatigue resistance of workpiece and workpiece.4) electrophoretic process is carried out to the carbon steel work-piece surface after reconditioning, sandblasting.5) constant temperature baking processing, is placed on workpiece in constant temperature baking, is heated to preset temperature, and is incubated the corresponding time, take out, make the surface effect of carbon steel work-piece reach optimum regime after cooling.
Claims (1)
1. a steel surface treatment process, is characterized in that: the method comprising the steps of: rubbing down process, pickling, pot galvanize process, reconditioning, sandblasting, phosphatization, electrophoretic process, constant temperature baking processing.
