Product Description

Vacuum gas quenching hardening Furnace for extrusion die Vacuum air-cooled furnace Horizontal real air quenching furnace

For heat treating purposes, “quenching” can be defined as the rapid cooling of a metal to impart some desired property such as hardness. Different metals and alloys require different quenching rates to achieve their optimum properties. Regardless of equipment design, gas quenching in vacuum furnaces involve the same basic principles.

The gas quenching process normally consists of the following sequence of events. First, the power to the heating elements is shut off. Next, the furnace chamber and quench loop are backfilled with a non-reactive gas, commonly nitrogen or argon. The quench blower then activates, forcing the gas through quench nozzles located circumferentially in a manifold that is part of the hot zone and into the hot load. As the gas passes over the load, it picks up heat. The hot gas then exits the main chamber and travels through the quench piping to a water-cooled heat exchanger, where it is cooled. After exiting the heat exchanger, the cooled gas is drawn back through the blower to be recirculated through the chamber in a continuous cooling loop.

Application

Quenching of high speed steel, tool and die steel, stainless steel.

Solid solution treatment of stainless steel and titanium alloys.

Magnetic materials Vacuum heat treatment of magnetic materials.

High temperature brazing and vacuum sintering.

Performance features

Convection heating, to achieve rapid and uniform heating of low-temperature strands.

The heating chamber structure in the furnace provides more uniform heating, less power loss and energy saving.

Using a new type of carbon felt composite material, it is resistant to high temperature and high pressure airflow erosion, and the heat shield has a longer service life and is easier to maintain.

High-speed and high-pressure fans and high-efficiency copper-copper heat exchangers achieve rapid cooling.

Alternate cooling method achieves uniform cooling and ensures minimal deformation of the workpiece.

The cooling pressure and wind speed of the locomotive are adjustable to achieve graded cooling.

The vertical furnace adopts screw drive, which is flexible, safe and reliable.

Optional graphite or all-metal heating chamber.

Optional fully intelligent industrial computer control and a manual operating system are available, which are easy to learn, understand and operate.
