CNG Cylinder Heat Treatment Machine#1

Hardening and tempering process made up the CNG Cylinder Heat Treatment Machine.
Hardening is a heat treatment method that heats the steel to 30~50℃ above the critical temperature for a period of time, and then uses water or oil to cool the work piece quickly. The purpose of quenching is to obtain a high hardness structure.
Tempering is quenching work piece to an appropriate temperature lower than the lower critical temperature, heat-preserve the metal cooled in air or water, oil and other media after a period of heat preservation.

Parameter of our CNG Cylinder heat treatment machine

1.Hardening Furnace Rated Temperature: ≤950℃, or design as your needs.

2.Heating Zone: 6zones (pre-heating: 1 zone, heating: 4 zones, soaking: 1 zone)

Temperature of each zone is separately controlled.

3.Tempering Furnace Rated Temperature: ≤680℃ , or design as your needs.

4. Working Procedures of the production line:

﹡Cylinders are loaded at transfer roller;

﹡Cylinders are transferred onto loading table and charged inside of hardening furnace chamber from one end of furnace door;

﹡Cylinders are horizontally heated inside of hardening furnace;

﹡After heating process, cylinders will be discharged out of chamber from the other end of furnace door;

﹡Cylinders is transferred inside of quenching tank;(cylinders are horizontally immerged in quenching water)

﹡After quenching, cylinders are transferred at loading table at front of tempering furnace;

﹡Cylinders are charged inside of tempering furnace chamber from one end of furnace door;

﹡Cylinders are horizontally heated inside of tempering furnace;

﹡After heating process, cylinders will be discharged out of furnace chamber from the other end of furnace door;

﹡ Air cooling process;

﹡ Cylinders are discharged out of furnace chamber, waiting for unloading.

Advantage of our CNG Cylinder heat treatment machine
1.Reduce internal stress and reduce brittleness. There is a lot of stress and brittleness in the quenched parts. If it is not tempered in time, it will often deform or even crack.

2.Adjust the mechanical properties of the work piece. After quenching, the work piece has high hardness and high brittleness. In order to meet the different performance requirements of various work pieces, it can be adjusted by tempering, hardness, strength, plasticity and toughness.

3. Stabilize the work piece size. Through tempering, the metal structure can be stabilized to ensure that no deformation will occur during the subsequent use.
4. Improve the cutting performance of some alloy steels.
