In the fields of precision machinery and high-end mold manufacturing, many long-shaft components, cylindrical parts, or large-diameter disc-shaped workpieces are subject to extremely stringent requirements regarding deformation following heat treatment. When processed in conventional horizontal furnaces, such workpieces are prone to bending or distortion—often due to the effects of gravity or the specific method used for loading them into the furnace. In contrast, high-vacuum, high-pressure vertical gas-quenching furnaces effectively resolve this technical challenge through their vertical loading configuration and optimized gas-flow distribution.

SIMUWU’s RVGQ-B1815 high-vacuum, high-pressure vertical gas-quenching furnace combines a high load capacity with a large effective working zone. It features a zoned heating design that ensures uniform furnace temperature, thereby increasing the pass rate for gas-quenched components. With a maximum gas-quenching pressure of up to 10 bar, the furnace enables ultra-fast cooling within just 6 minutes. It is equipped with a three-stage vacuum pumping system—including a diffusion pump—capable of maintaining an ultimate operating vacuum level of 10⁻⁴ mbar.
