Hebei elbow manufacturers to introduce the quenching and normalizing of the elbow

Elbow manufacturers on the elbow quenching: quenching is to heat the elbow to the critical temperature above, heat preservation for a period of time, and then quickly put in the quenching agent, so that its temperature suddenly reduced, at a rate greater than the world critical cooling rate to improve the cooling, and get a good heat treatment method.Quenching can increase strength and hardness, but to reduce its plasticity.Quenching commonly used quenching agents are: water, oil, alkaline water and salt solutions.

Elbow manufacturer's normalizing of elbow:Normalizing is to hot bend heated to above the critical temperature, the thermal bend all shift more evenly, and then in the air natural cooling heat treatment method, normalizing can eliminate the net cementite hypereutectoid hot-pressing elbow to the hot elbow is strict to the fire, improve comprehensive mechanical properties, low requirements for the elbow use the normalized instead of the quenching process is more economic.

The differences between quenched and normalized elbows are described above.

What kind of seamless elbow forming process is divided into?

When producing seamless elbows we think of stamping, forging, rolling, expansion, and bending processes.The following is a brief introduction to the above processes:
