产品详细信息

 

As the large castins, lathe bed castings must be subjected to heat treatment in order to improve the performance itself, and improve the intrinsic quality of iron castings. Usually the heat treatment does not change the overall shape and chemical composition of the workpiece, but by changing the microstructure within the workpiece, or to alter the chemical composition of the workpiece surface to improve the performance of the work piece. Its characteristic is to improve the intrinsic quality of the workpiece.
 
整体热处理是对工件整体加热,然后以适当的速度冷却,以改变其整体力学性能的金属热处理工艺。钢铁整体热处理大致有退火、正火、淬火和回火四种基本工艺。
 
Overall heat treatment is to heat the workpiece as a whole, and then cooled at a appropriate rate to change the metal heat treatment process overall mechanical properties. Overall heat treatment of steel includs annealing, normalizing, quenching and tempering .
 
 
床身机床铸件退火:
热处理的退火种类:常见的退火工艺有:再结晶退火,去应力退火,球化退火,完全退火等。退火的目的:主要是降低金属材料的硬度,提高塑性,以利切削加工或压力加工,减少残余应力,提高组织和成分的均匀化,或为后道热处理作好组织准备等。
The types of Annealing process includs recrystallization annealing , stress relief annealing, spheroidizing annealing, totally annealing,etc. The main purpose is to reduce the hardness and improve cutting ability and to prepare for after quenching.
