vacuum furnace
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.
