The bestselling heat treatment furnace "High Shifter" has evolved further with the latest features!
Born in 1954 as a full-fledged atmosphere heat treatment furnace, the "High Shifter" has received high praise in the automotive, bearing, machinery, and various other industries. Even now, it has delivered over 1,200 units as an energy-saving general-purpose heat treatment furnace that significantly shortens drying, heating, and seasoning times, and its demand is becoming increasingly diverse. Chugai Ro Co., Ltd. has significantly revamped various functions to meet these requests. The "New High Shifter" has achieved further evolution by pursuing ease of use, environmental improvements, and increased productivity. 【Features】 ■ Lower surface temperature of the furnace shell ■ Reduced cycle time due to increased combustion volume ■ Improved operability and maintainability ■ Reduced distortion of treated materials *For more details, please refer to the PDF materials or feel free to contact us.
Efforts towards new technology
The development of "multi-cooling control for martempering technology and equipment aimed at achieving lower distortion in carburized products." Our company's unique hot gas furnace has many excellent advantages compared to salt furnaces, such as energy-saving and environmentally friendly features, as well as solutions to the 3K (difficult, dirty, dangerous) issues. However, the hot gas alone has limitations in "cooling capacity." This time, we have addressed that issue and further developed and evolved it into the carburizing martempering furnace.
A heat treatment furnace that achieves high-precision distribution not obtainable with an electric furnace.
Ideal for high-temperature firing and heat resistance testing! Capable of operating at up to 750°C and continuously at 700°C. The adoption of hot air circulation achieves a high-precision temperature distribution that cannot be obtained with electric furnaces.
Continuous heating at 500℃ is possible. A heat treatment furnace that also achieves high-precision temperature distribution.
Supports various optional specifications such as program operation and N2 gas purge.
Continuous work input. Ideal for large-scale drying and heat treatment.
Continuous workpieces are fed into the system for drying and heat treatment using chain conveyors, net conveyors, and the like. Temperature control is performed for each zone. If heating adversely affects the equipment inside the system due to a large amount of moisture, solvents, or tar, protective measures such as using a muffle type heater are implemented.
Experienced technical staff in the environmental business will be responsible for handling matters until the end.
This is an environmentally friendly and clean incinerator that significantly reduces dioxin levels. It also fully complies with pollution regulations! Our experienced technical staff in environmental projects will responsibly handle everything until the end. We not only offer new installations but also repair, maintenance, and modification work for existing furnaces. Please feel free to request a catalog, estimate, or consultation. As of December 2010, our construction achievements include cart-type heat treatment furnaces, annealing furnaces (heating and cooling zones), heavy oil furnaces (lintel and column repair work), maintenance, and replacing refractory materials with bricks (energy-saving change to ceramic fiber), as well as repair work on the brick arch of heating furnaces. For more details, please contact us or refer to the catalog.
