製品の特徴 (ピット炉)

Designed for Vertical Heat Treatment

This pit furnace is specifically designed for the vertical heat treatment of long and narrow workpieces such as bars and tubes, and is suitable for laboratory and pilot-scale applications. It features top loading and a deep furnace chamber, making it convenient to place workpieces vertically inside and ensuring uniform temperature distribution. It is particularly suitable for heat treatment of workpieces with a large length-to-diameter ratio.

Precise Multi-Zone Heating

Utilizing multi-zone independent temperature control technology, the Pit Furnace features zoned temperature control along the height of the heating chamber, effectively eliminating vertical temperature gradients. Each temperature zone can be independently set according to process requirements, ensuring uniform heating of long workpieces from top to bottom and excellent temperature consistency.

Laboratory-Optimized Design

Compact, customizable, and highly stable, this furnace is optimized for workflows in research institutes, materials laboratories, and tool development. Its small footprint allows for flexible placement on laboratory benches or dedicated racks, facilitating easy operation.

Atmosphere Flexibility

It can be configured with various atmospheres (air, nitrogen, argon, etc.) to meet the atmospheric requirements of different materials. 5. Equipped with a gas flow control system, enabling precise atmosphere regulation and preventing material oxidation at high temperatures.

Top Loading, Convenient Operation

The top loading structure allows workpieces to be vertically hoisted or placed into the furnace from above, simplifying operation. The deep heating chamber design ensures that long workpieces can be completely placed within the constant temperature zone, eliminating the need for horizontal placement and preventing workpiece deformation.
