Vacuum Oil Quench Furnace

Product Feature

◆ A multi-stage vacuum pump (backing pump + Roots pump) achieves high vacuum, effectively preventing oxidation and decarburization, ensuring smooth workpiece surface finish and stable performance.

◆ The heating chamber utilizes imported graphite felt for a long service life, reducing heat loss, improving energy efficiency, and extending service life.

◆ A maximum temperature of 1320°C is achieved, with a temperature control accuracy of ±1°C and furnace temperature uniformity of ±5°C. Multi-stage temperature programming is supported to meet the heat treatment requirements of various materials.

◆ Equipped with a large-capacity oil tank, powerful stirring device, flow guide system, heat exchanger, and heater, it ensures quenching stability and fast cooling speeds to meet the requirements of martensitic transformation.

◆ Adjustable cooling speed: By controlling the oil stirring speed, oil surface pressure, and quenching oil temperature, the cooling requirements of different materials can be adjusted to minimize deformation and cracking.

◆ A patented internal drive mechanism with a unique drive method fundamentally eliminates the risk of quenching oil entering the heating chamber.

◆The vertically opening furnace door not only saves space and offers efficient opening and closing, but also seamlessly integrates with automated production lines, effectively improving overall production efficiency.

◆The integrated PLC, equipped with a program controller or computer interface, touch screen, and recorder, provides real-time monitoring of furnace vacuum, temperature, and pressure, supporting remote fault diagnosis and process traceability.
