Loading Horizontal Quench Furnace Aluminum Heat Treat Furnace Double Chamber 1350 Degree

steel heat treatment Vacuum Horizontal Double Chamber Vacuum Oil Quenching Gas Cooling Furnace with 1350 degree

◆ Heating system and Insulating

The insulation of the rectangular hot zone is made of hard felt graphite plates covered with graphite foil. The hard felt insulation, which is tight from all sides, reduces the thermal loss to a minimum. The joint and fixer made of CFC-strips material, which extends the effective life of heating chamber.
 

The furnace is installed with a S type thermocouple and two N type thermocouples to control the working temperature and the temperature differences of work pieces.
 

The vacuum heat treatment plant, type VKNQ is a simple, reliable and easy maintenance furnace with a horizontal, cubical zone. Heaters and heating insulation are made of graphite. The 12 heaters are equally arranged around the furnace wall which effectively ensures the uniformity of the temperature in furnace and easily to be replaced. The water-cooled current lead-throughs, made of copper, are mounted vacuum-tight and pressure tight into the vessel, which extend the copper electrode’s life and improved the reliability.
 

◆Convective Heating
 

Because of low efficiency of radiative transfer below 800℃, the furnace is flooded with 1.5-2 bar inert gas( high purity N2) which is agitated by convective motor. During convective operation, the excellent temperature uniformity in the working zone can be obtained, also heating efficiency is improved.

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.
