Horizontal double chamber oil quenching vacuum furnace

No waste gas, dust, waste water, waste residue, no environmental pollution, improve working conditions, called bright heat treatment, clean heat treatment and green heat treatment. Vacuum furnace heating workpiece without oxidation and decarburization, no alloying elements dilution, defatted degassing, vacuum distillation, avoid hydrogen embrittlement, can realize the grading isothermal quenching, can control the heating and cooling, lay the foundation for automation, flexible production.

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 parts surface and the core is the main reason for quenching deformation and cracking due to the uneven heating and cooling. The quenching heating and subsequent insulation are for the full dissolution of the alloy element and the austenitic homogenization.

Should be set according to relevant technical data are given to quenching heating temperature, requiring high secondary hardening and tempering stability limit, to prevent deformation and cracking occasions in lower limit, the heat preservation time refers to the center of whole furnace the thickest part to the stay time after quenching temperature, with the amount of electric power, furnace charging, furnace charging mode and factors such as related parts.
