Big and long axis is one important part in mechanical product. In order to improve its strength and hardness, heat treatment is an essential step of whole production process.

Henan Tianli Thermal Equipment Co.,Ltd, we can provide you detailed and one full set of heat treatment production line and centralized control system.

For heat treatment of long axis, you can choose deep pit type electric resistance hardening furnace and tempering furnace, water cooling tank and car bogie gas fired furnace. Our engineer can design furnace working area size according to workpiece's size. Pit type furnace can reduce the axis deformation. While, covering area of pit type furnace is small, operation is easy.

Last year, we design and manufacture one full set of production line for heat treatment of long axis for domestic customer. Now they has been put into use at customer’s site. This production line include four sets pit furnaces, four cooling tanks, one gas heating furnace, one electric resistance furnace.Specially, customer give us high approval.
