DN125 SCH80 Hot pressingelbow,(Skype:xiujin.wang16)
Product Overview: pressing elbow is one of the fittings.The hot pressing Elbow is the use of the hot-pressing process produced an elbow
Description: hot pressing elbow fittings a. The hot pressing Elbow hot-pressing process produced an elbow. Thermocompression elbow is molded using specialized processing equipment after the tube is heated, and then cutting was heated to above the critical temperature, and incubated for a period of time into the quenching agent soon after its temperature is suddenly reduced to greater than the critical cooling rate of the rapid cooling method made elbow.
Approach
Quench
Quenching elbow heated to above the critical temperature, and incubated for a period of time, and then quickly into the quenching agent, its temperature is suddenly reduced to greater than the critical cooling rate of speed rapid cooling, to obtain a martensite-based the heat treatment method of the imbalance tissue. The quenching can increase the strength and hardness of the steel, but to reduce its plasticity. Quenching in the quenching agent commonly used are: water, oil, alkaline and salts solution.
Normalizing
The normalizing is thermocompression elbow heated to above the critical temperature, so that the thermocompression elbow into all homogeneous austenite, the method of heat treatment and natural cooling in the air. The normalizing eliminate addition to the hot pressing elbow mesh hypereutectoid cementite, normalizing for hypoeutectoid hot pressing elbow refinement of the crystal lattice, improve the mechanical properties, less demanding elbow normalizing It is more economical to replace the quenching process.
Standard manufacturing standards
Manufacturing the GB electricity standard water standard, American standard, German standard, Japanese standard, the Russian standard and other standards can be divided into.
