Advantages for Hardening and tempering machine for pipe

1.Uniform heating: The angle between roller axis and bars axis is 18 ~ 21 °. The bars is rotating and go forward at the uniform rate for uniform heating. Rollers between furnace are 304 non-magnetic stainless steel and water-cooled.

2.Uniform cooling:To meet the requirements of different hardenability, spraying system adopts multi-level spray cooling and the pressure & flow in water spray ring at all levels is adjustable.The pipes will be placed in the middle of spray ring to ensure uniform pressure and flow. So the pipes needn’t straightening after heat treatment with our line. The surface hardness difference is very small, which is only HRC3.

3.Closed-loop temperature control system: Our engineer will set the process parameters in the system, and when the heating temperature is too high or too low, the system will adjust the temperature to the required temperature through adjusting power.
