YQ Chain
1. Heat Treatment.: In heat treatment equipment, used in a variety of auxiliary medium at high temperature, improve the organizational structure of the parts, improve various items performance
2. Carburization:Place in heat treatment equipment parts were heated to a certain temperature and heat preservation time, and then pass into the carbon, medium carbon into the workpiece surface, chain in order to improve the hardness and wearesistae.3 Quenching Parts :after heated to a certain temperature in heat treatment equipment, heat preservation time, and then according to the requirements in different medium cooling, thus improve parts hardness.
4 Tempering:After quenching parts at a certain temperature in the heat treatment equipment for heating, cooling and heat
preservation time after.Parts after tempering can reduce the quenching hardness, eliminate the quenching stress,improve the toughness.
5.Black Oxide/Bluing:Using organic polymer polymerization principle, the use of heat treatment process in the process of tempering heat black film.
