Tray pusher type continuous gas carburizing furnace

Tray pusher type continuous gas carburizing furnace

A groundbreaking carburizing furnace that simultaneously achieves significant energy savings and compactness.

This is a compact facility suitable for small variety mass production, improved from a well-established pusher-type continuous furnace. By separating the furnace body into three chambers—burn-off and heating chamber, carburizing diffusion chamber, and cooling retention chamber—using intermediate doors, this energy-saving type reduces the energy consumption per unit by approximately 36% compared to conventional models. Our developed quenching method, "one tank three-stage quenching," is a quenching system that minimizes distortion during the phase transformation by ensuring uniform material temperature before martensitic transformation. By adopting this system, low distortion that is not constrained by the shape of the material can be achieved. 【Features】 ■ Equipment improved from a pusher-type continuous furnace ■ Suitable for small variety mass production ■ Compact ■ Energy-saving type *For more details, please refer to the PDF document or feel free to contact us.

Vacuum Carbonitriding Furnace "HV8"

Vacuum Carbonitriding Furnace "HV8"

In the heat treatment of martensitic stainless steel, please make sure to utilize this vacuum carburizing furnace.

We would like to introduce our "HV8." In stainless steel with a high chromium content, chromium carbides precipitate at the grain boundaries around 600 to 700°C. Since oil cooling can cool nearly 10 times faster than gas cooling, it suppresses the precipitation of these chromium carbides and does not compromise corrosion resistance. 【Benefits】 ■ Increases hardness ■ Suppresses the precipitation of chromium carbides ■ Appropriate heat treatment temperature *For more details, please refer to the PDF document or feel free to contact us.

[Subsidy-eligible equipment] Contributing to the realization of a low-carbon society through operations that reduce gas consumption and CO2 emissions! Achieving heat treatment quality equivalent to gas carburizing furnaces with unique technology!

The "Z-TKM" is a vacuum carburizing furnace that contributes to reducing CO2 emissions and achieving a carbon-neutral low-carbon society. By combining unique technologies, it can cut factory CO2 emissions (SCOPE 1) by 97% compared to conventional equipment (based on our company's comparison). (A small amount of CO2 from carburizing raw material gas is generated.) Additionally, for CO2 from electricity (SCOPE 2), further reductions are possible by utilizing green energy sources such as green electricity, hydrogen, and ammonia. While inheriting the high versatility, economy, and reliability of the best-selling TKM series, it achieves high environmental performance and productivity by adopting new charge loading methods, high-insulation hot wall structures, and rapid uniform heating and cooling mechanisms. **Features of Z-TKM** - Safe environment: No smoke or fire - Quality compatibility: Equivalent quality to conventional gas carburizing through a combination of reduced pressure carburizing and atmospheric quenching - Space compatibility: Fully compatible with the best-selling TKM series - Operability: Easy operation and maintenance through a unique operational support system - Reliability: Stable operation without in-furnace driving mechanisms - Heating source: Standard electric heating (hydrogen burners and utilization of green energy are also possible)
