The vacuum oil quench furnace is a cutting-edge solution for heat treatment processes, specialized in vacuum oil quenching, annealing, and air cooling of alloy structural steel, bearing steel, spring steel, die steel, and high-speed steel. What makes this product stand out is its modular furnace chamber design, which ensures exceptional temperature uniformity-critical for consistent, high-quality results across every workpiece. Whether you're manufacturing precision components or industrial tools, this vacuum oil quench furnace delivers reliability and efficiency that elevates your production line.
Equipped with ceramic-free supported heating elements, the product maintains stable insulation performance for up to 5 years, reducing maintenance costs and downtime. Its internal material cart features an overlapping integral telescopic structure with frequency conversion speed control, adopting a "slow-fast-slow" operation rhythm for smooth material transfer and short transfer times. With a built-in heat exchanger and forced air circulation cooling, plus dual oil stirring and oil injection cooling options, it minimizes workpiece deformation while ensuring fast, uniform cooling. The large-capacity quenching oil tank, paired with external circulation and heat exchanger cooling, optimizes oil temperature control for superior quenching effects.


Boasting a large loading capacity for its class, the product boosts production efficiency, while the fully automatic external cart with remote control allows one operator to handle loading and unloading-saving labor costs. Finished with automotive-grade paint that resists discoloration for 3 years, it combines durability with sleek design. Ideal for aerospace, automotive, and precision engineering industries, this vacuum oil quench furnace is your trusted partner for achieving superior material properties and consistent performance in every batch.
