Embodiment Construction

[0015] like figure 1 As shown, the diesel engine cylinder liner processing technology of the present invention includes the following steps: step a, hanging paint: metal mold, baffle plate preparation: remove the residual paint in the inner cavity of the metal mold after being wetted with water, enter the kiln for preheating, and front and rear baffles The inner side of the board is pounded with water glass sand, scraped flat, hardened by adding CO, painted with lead powder, and put into the kiln together with the metal mold. 250kw, electric kiln capacity is 210kw, for this reason, electric furnace, electric kiln can not transmit power at the same time, paint preparation; paint components: quartz powder, bentonite, powdery lead powder, flake lead powder, diatomaceous earth, water glass and Appropriate amount of water, the procedure of adding the above materials (except water glass) into the mixer: water, lead powder, bentonite, diatomaceous earth, quartz powder, stirring time ...

Abstract

The invention discloses a process for processing a cylinder sleeve of a diesel engine. The process comprises the following steps of: a, coating paint, wherein a metal die and a baffle are prepared, and the paint is prepared; b, smelting and pouring, wherein the smelt process controls the carbon and silicon equivalent C to be between 3.7 and 3.9, the silicon carbon ratio Si / C to be between 0.6 and 0.73, and the pouring requirement is as the specification; c, repairing a pouring system, repairing the inner wall of a quantitative pouring packet with refractory bricks and water glass sands, introducing CO to harden the inner wall of the quantitative pouring packet, coating the paint and drying; d, demolding, thermally treating and delivering, wherein, in cast demolding, a metal die pin, front and rear baffles can be removed after 8 hours, the cast is impacted by a hammer by moving from the small end to the big end; and e, thermally treating the cast, wherein the cast is subject to shot blasting treatment and aging treatment. The process for processing the cylinder sleeve of the diesel engine has the advantages of high processing accuracy, precise process procedure and high quality of processed products.

Description

technical field [0001] The invention relates to a process for processing a cylinder liner of a diesel engine. Background technique [0002] The traditional diesel engine cylinder liner processing technology, because the process flow is not fine enough, and the process requirements are not precise in the material hanging link, resulting in insufficient precision of the piston processed by this processing technology, and poor product quality. Contents of the invention [0003] The object of the present invention is to provide a process for processing a cylinder liner of a diesel engine. [0004] The technical scheme that the present invention adopts for realizing the above object is: a kind of diesel engine cylinder liner processing technology, comprises the following steps: [0005] Step a, hang paint: preparation of metal mold, baffle, paint preparation; [0006] Step b, smelting, pouring, smelting process control: carbon-silicon equivalent C is 3.7-3.9, silicon-carbon r...
