- Brother Furnace
Our Vacuum Heating Quenching and Tempering Furnace, designed specifically for processing carbon steel and AISI 420 martensitic stainless steel coils and plates, has completed factory acceptance testing and is ready for shipment.
The system ensures outstanding thermal uniformity across the workload, sustaining extreme temperatures up to 1350°C. It is precision-engineered to minimize distortion during quenching and to provide consistent stress-relieving tempering, making it ideal for high-carbon and low-alloy materials.
With tight temperature control and a high-vacuum sealed chamber, the furnace guarantees decarburization-free hardening, effectively suppresses oxidation, and enables repeatable microstructural refinement.
Vacuum Heating Quenching Tempering Furnace for Carbon Steel and AISI 420 Features
- The Chamber size is 500x500x700mm (WxHxD)
- The heating chamber is composed of graphite heater graphite soft felt and hard felt, the max operation temperature is 1350℃.
- The multiserial graphite spray nozzle is located inside the heating chamber along with the induction inwall. The gas uniform was sprayed from the spray nozzle during gas quenching.
- The material platform is composed of graphite support, a hearth, and an Al203 sticker. This structure will prevent the adhesion between the platform and the hearth during high temperatures.
- The heat field can also use high-temperature molybdenum belt heating, and molybdenum foil heat shield furnace. The heat field has no volatilization, no impurities, and no pollution to the heat treatment workpiece.
- Gas cooling system: which is composed of a high press wheel blower, multistage high-efficient copper heat exchanger, and duct deflector. Filling high purity N2 or Arduring gas cooling, spray to workpiece through duct deflector to achieve workpiece uniform cooling.
- The gas cooling pressure is adjustable from 1-10bar.
- Max cooling rate: from 1150℃ to 250℃ less than 7min. (The cooling water temperature is lower than 35 ℃)
