OQ series vacuum oil quenching furnace is a high-end heat treatment equipment that is heated in a vacuum environment and cooled rapidly by quenching oil. By accurately controlling the vacuum degree, temperature, quenching oil cycle and intelligent control process, it significantly improves the hardness, wear resistance and dimensional stability of the workpiece, and realizes an efficient and energy-saving heat treatment process while ensuring the surface quality and performance of the workpiece. Mainly suitable for alloy steel, tool steel, bearing steel, stainless steel, superalloy and other materials vacuum oil quenching, annealing, gas cooling and bright treatment, especially suitable for complex workpieces with high hardenability requirements, both vacuum no oxidation and oil quenching high cooling rate advantages, widely used in mold manufacturing, tool processing, precision machinery and other fields. It solves the oxidation, pollution and deformation problems of the traditional oil quenching process, and becomes the core equipment for precision hardening of high alloy materials.
