oil quenching vacuum furnace in heat treatment process application
Oxidation corrosion is one of the fatal defects in product parts. In the past, many products of a domestic company were quenched by salt furnace. When the rainy season comes, the parts must be surface treated within a week. Otherwise, the residual salt will corrode the workpiece, which will lead to the quality problem of batch scrap. In this season, the problem is usually solved by surface treatment immediately after heat treatment. However, due to the large output and variety of products, this method aggravates the workload of the surface treatment workshop during the construction period, resulting in pressure on production arrangements. In order to alleviate this pressure and achieve balanced production, VQ02-100 type oil quenching vacuum furnace was introduced.

Processing process analysis and new equipment support capacity of parts produced by a domestic company for a variety of thin-walled, complex shape, folded edges, no through-holes and other design parts, and the surface after heat treatment is not allowed to oxidize decarbonization, the original process used a salt bath furnace heating, although it can effectively prevent decarbonization, but often residual salt retention table of work pieces. Because of the difficulty of thoroughly cleaning up, the surface will cause waste due to oxidation corrosion. The workpiece heated in vacuum can remove the grease on the surface, decompose the oxide and activate the surface to improve the surface quality. VQO-100 double-chamber quenching and tempering furnace can ensure high vacuum (10Pa) conditions, first of all, fully meet the requirements of workpiece non-oxidation decarbonization heating and quenching; secondly, the equipment is controlled by the program, automatic execution of the set process parameters, eliminating the influence of human factors; thirdly, the temperature control system uses PID to adjust automatic temperature control, furnace temperature uniformity. It can be controlled within 2 C.
