It is suitable for long-term continuous high-temperature working environments.
Product Features (Pit Furnace)
- Pit Structure, Suitable for Heat Treatment of Long Workpieces
This pit furnace adopts a vertical deep-pit furnace structure with furnace chamber dimensions of 300×200×200mm. Workpieces are loaded from the top, making it particularly suitable for the vertical heat treatment of long parts such as long shafts, rods, and tubes, effectively preventing bending deformation at high temperatures.
- Top-Opening Door for Convenient Operation
The furnace door uses a top-opening design, facilitating easy operation and workpiece hoisting and retrieval. The top loading structure allows long workpieces to be completely placed within the constant temperature zone, eliminating the need for horizontal placement.
- Silicon Carbide Rod Heating with Quartz Protective Tubes
The heating elements are silicon carbide rods, vertically installed around the furnace chamber to create a uniform heating field. Quartz protective tubes are added to the heating elements to effectively prevent corrosion and mechanical damage from the atmosphere, extending their service life.
- Adjustable heating rate, up to 15℃/min
The heating rate can be freely adjusted within the range of 1℃/h to 15℃/min, allowing users to flexibly set the heating speed according to different materials and process requirements.
