Vacuum furnace

It is a vacuum furnace that eliminates the need for post-processing acid cleaning and degreasing, thereby improving work efficiency and offering potential energy-saving benefits.

When heat treatment is performed in the atmosphere, steel reacts with oxygen and forms oxide scale on the surface, so a vacuum furnace is used when it is necessary to avoid an oxidizing atmosphere. 【Features】 ■ Rapid cooling with pressurized gas is possible ■ Seamless temperature measurement in multi-chamber types is possible 【Examples of Achievements】 〇 Batch-type vacuum degreasing furnace 〇 Pit-type vacuum annealing furnace 〇 Batch-type vacuum decarburization furnace 〇 Snake chain-type vacuum oil removal device, etc.

Firing furnace / Sintering furnace

By reusing exhaust gas for preheating, cost reduction can be achieved.

The atmosphere gas used in the furnace can be reused as preheating in the space before heating without being discarded. As a result, the energy consumption is lower and more energy-efficient compared to heating from room temperature. Customization is also possible for degreasing and adjusting the purity of the atmosphere gas. San Furnace listens to your requirements regarding processing volume, work size, applications, and upstream and downstream processes, and proposes the optimal firing furnace or sintering furnace, including surrounding areas. 【Problem Solving】We have addressed the following issues: ■ It is wasteful to discard hydrogen exhaust gas. ■ Manual changes to processing temperatures are being made in the pusher furnace. ■ Speed switching was done with limit switches, but misalignment of the switch position occurs. The "firing and sintering furnace" can mass-produce high-precision parts and is used in the manufacturing of various mechanical components, including automotive parts. Continuous processing from degreasing to firing and sintering, as well as automatic transport from the degreasing process, can be designed. Please consult us for small lot production, heat treatment testing, and small sample manufacturing. *For more details, please contact us or download the PDF.
