Product general description

The salt quenching roller hearth furnace developed by Yajie is a new generation salt quenching equipment, adopts Yajie many new patents,idely used for bearing industries,automobile parts industries processed by atmosphere salt quenching Martensite and Bainite quenching.

Yajie's salt quenching roller hearth furnace plant is composed by loading table, storage
table, pre-washing machine and dryer, transferring cart, protective atmosphere roller
hearth heating furnace, salt quenching tank, air cooler, water cooler, afterward washing
machine and dryer, tempering furnace, unloading table, salt evaporator etc. The complete
plant could be customized by different combinations to fulfill different requirements.

Product structure and character

● The loader adopts the lifting table designing which makes it easy for operators to load and unload, a weight scale could be added to realize auto recording of the weight to avoid over loading.

● Pre-washing machine adopts the designing of rinsing and spraying and equipped with ultrasound washing system to increase the cleanliness of the surface at maximum to make sure the quality of the appearance.

● Adopting Yajie patent roller and ceramic roller assembly (Patent No. : ZL201420064313.9), fast disassemble structure which could realize the fast exchanging of the lower rollers under high temperature. It makes maintenance more conveniently; the structure could effectively reduce the heat short cut, the energy saving result is obvious; the ceramic roller could reduce the risk of crooked; and also designed with roller breaking detecting system to make customers free of anxious.

● The patent of salt quenching and tempering in the same tank (Patent No. : ZL201410173288.2):

● The patent of quenching and tempering process in the same salt tank which realized the recycling of the thermal to reduce the power consumption.

● The selection of tempering : Yajie's salt quenching roller hearth furnace can customized with different tempering furnace according to different demands and products , they are quenching tempering isothermal within the same tank, roller hearth tempering furnace, chain be lttempering furnace and many more type of furnaces for choice. Yajie 3 floors roller furnace realized the perfect combination of low power consumption and long time tempering process; The chain belt tempering furnace adopts the inner chain belt and the sealed door, compared with traditional chain belt furnace, it could reduce the operation power consumption obviously.

● The selection of quenching method: designed with open quenching and closed quenching for choice, the color of parts after processed is uniform black and blue,the surface color is excellent and the later blasting process could be canceled.

● Full recovery of residual salt, zero emission, good workshop environment, environmental protection up to standards.

● The choice of heating method: Yajie choose priority of high quality heating system supplier domestic and overseas to guaranty the life time and high reliability. According to the actual condition of the customer, the heating mode could be selected flexibly.
The gas heating system has superiority of operation costs.

Industrial Gas Intensive Purification Equipment

Industrial Gas Intensive Purification Equipment

In the controlled atmosphere heat treatment sector, natural gas (propane) has found ever-increasingly extensive application. With the demand on quality of heat treatment process becoming ever-increasingly stricter, the effect on quality of processed product produced by the sulphur adverse content in natural gas (propane) has become a public concern. Particularly the effect of sulphur on the formation of nonmartensitic surface on processed product produced by sulphur has been borne out to a large extent. To tackle with the problem, Yajie has developed a kind of natural gas (propane) desulphurization equipment through study over years and incorporation of advanced domestic and overseas technologies in this respect. With the use of this equipment, a supply of natural gas with extremely low content of sulphur can be steadily ensured
