Cast iron artistic manhole cover production process

Abstract

The invention provides a cast iron artistic manhole cover production process. The cast iron artistic manhole cover production process comprises the steps of S1, machining panel dies through a customized decorative pattern machine tool; S2, manufacturing cast iron manhole cover blanks, conducting treatment, grinding and repairing on the blanks, conducting degreasing on the blanks, removing releaseagents and conducting quenching; S3, spraying metal and non-metal accelerants and conducting drying; S4, spraying primer, conducting high-temperature drying, spraying epoxy middle coating, conductinghigh-temperature drying, spraying epoxy metal top-coat and conducting high-temperature drying; S5, conducting epoxy resin coloring on the surfaces of the blanks, spraying surface sealing agents and conducting high-temperature drying; and S6, conducting cooling, checking, packaging and warehousing. Through the cast iron artistic manhole cover production process, the surface pattern layer of each manhole cover is not easy to peel off. The image and the integrated environment grade of a project are improved aesthetically from the landscape.

Description

Technical field [0001] The invention relates to the technical field of manhole cover production, in particular to a production process of cast iron art manhole cover. Background technique [0002] Manhole covers are usually used to cover deep wells under roads to prevent people or objects from falling. Manhole covers are usually metal manhole covers, generally round, used for green belts, sidewalks, motor vehicle lanes, docks and alleys. The function of the manhole cover is relatively simple, that is, to cover the manhole to ensure safety. However, manhole covers are commonly used in various areas of life, such as shopping plazas, living quarters, etc. [0003] In the prior art, in order to increase the function of beautifying the environment of the manhole cover, a picture is usually drawn on the surface of the manhole cover, and resin is directly applied to the surface of the manhole cover to form a pattern. However, the disadvantage is that the surface pattern layer is easy to...

Problems solved by technology

[0003] In the prior art, in order to increase the beautification function of the manhole cover, pictures are usually drawn on the surface of the manhole cover, which directly smears resin on the surface of the manhole cover and forms a pattern. However, its defect is that the surface pattern layer is easy to fall off
