Heat treatment vacuum furnace quench oil cooling

Heat treatment vacuum furnace is heated by medium temperature and high temperature salt bath furnace. It is used to grade isothermal cooling and tempering with low temperature alkaline bath and nitrifying bath.

However, due to the salt bath furnace heating exist many disadvantages: barium chloride used toxic raw materials, the environmental pollution by waste gas, waste residue, quenching homework and deoxidization in dregs, employees in front of the furnace under high temperature radiation, hard working conditions, quenching oil, black smoke billowed from the roof, the alkali bath, nitrate bath waste collection and treatment of difficult, these are the heat treatment workshop of dirty, disorder and poor part of the reason. To this end, we can no longer afford to sacrifice the environment and the health of our employees in exchange for immediate benefits. Government departments have ordered the elimination and prohibition of new bath equipment.

Horizontal double chamber high pressure gas quenching and oil quenching vacuum furnace, suitable for die quenching, should put the volume or wall thickness of similar parts with the furnace processing, to set appropriate uniform heat preservation time, including heating temperature, heating rate, holding time, cooling rate, heat treatment process parameters, such as vital effect on the capabilities of the parts.

The temperature difference between the surface and the core of the parts is the main reason for the deformation and cracking of the quenching. The quenching heating and subsequent heat preservation are for the alloy elements to dissolve and the austenitic homogenization.
