The quenching and tempering production line includes various processes such as feeding, steel tube heating, quenching, quenching cold bed, tempering heating, tempering cold bed, cold straightening, flaw detection and cutting. The whole line should have the characteristics of high automation, data tracking, stable operation, fast speed, safe work and environmental protection.

1 process flow:

. 1 .1 refining process:

Feeding - quenching heating - quenching - quenching cold bed - tempering heating - tempering cold bed - cold straightening (twice straightening) - flaw detection - blanking

. 1 .2 normalizing treatment process :

Feeding - normalizing heating - normalizing - normalizing cold bed - cold straightening (twist straightening) - blanking
