Abstract

The invention relates to a large casting surface finishing process. The large casting surface finishing process comprises the following steps that S01, the surface of a casting is polished through abrasive paper; S02, the polished surface of the casting is coated with a hydrochloric acid solution; S03, the surface of the casting continues to be coated with deionized water for cleaning; S04, the surface of the casting continues to be coated with degreasing fluid; S05, the casting is heated to 100 DEG C, and then the surface of the casting is coated with powder paint; S06, the surface of the casting is subjected to fusing treatment; S07, the surface of the casting is polished through the abrasive paper; and S08, after polishing is completed, the surface is cleaned through the deionized waterand dried. The overall hardness of the surface of the casting is improved, the decoration performance of the casting is obvious, the mechanical performance is good, the corrosion resistance is high,the impact resistance is high, the hardness is high, and the abrasion resistance is good.

Description

technical field [0001] The invention relates to the field of casting, in particular to a large-scale casting surface finishing process. Background technique [0002] For some large castings, especially large castings with a weight of more than 2 tons and a maximum of 20 tons, the surface of such castings has unevenness and cannot directly meet the requirements of assembly. Therefore, it needs to be trimmed , so that the casting meets the requirements of use. [0003] At present, there are problems in the trimming process for castings that are complicated and the effect is not obvious, so it needs to be improved. Contents of the invention [0004] The technical problem to be solved by the present invention is: to overcome the deficiencies of the prior art, provide a large-scale casting surface finishing process, and solve the problems that the current casting finishing process is complicated and the effect is not obvious. [0005] The technical solution adopted by the pre...
