Brief Description:
Tempering can be accomplished by soaking entire parts in the furnace for periods of time sufficient to bring the tempering mechanism to the desired point of completion or by selective heating of certain portions of the part to achieve toughness or plasticity in those area. Lots of mistakes with the heat treatment were done in reference to a wrong or to a too short tempering process. Therefore it is most important to reach the needed tempering capacity as well as a high thermal uniformity and an efficient cooling time with the tempering furnace. Beyond this the parts should not lose their metallic shine surface after tempering.
The Jen Long vacuum tempering furnace equipments not only fulfill those requirements through installed Ni, Cr, or graphite heating linesĦBSUS304 heat-shield, vacuum pump stand and a controllable fast gas cooling system but also have developed to meet the diversifying needs of the market with versatile, reliable and user-friendly designs.
