工業用ピット炉

An industrial pit furnace is a vertical, deep-well structure of high-temperature heat treatment equipment, widely used in metal heat treatment, machining of long shaft workpieces, and heating of large workpieces. This type of pit furnace effectively saves space through vertical loading and achieves uniform and stable heating, making it one of the important furnace types in industrial production.

The equipment employs advanced heating and temperature control systems, making it particularly suitable for processing long or large workpieces, and it is widely used in the metallurgical and machinery manufacturing industries.

製品の特徴 (工業用ピット炉)

Vertical Deep-Well Structure, Designed for Long Components

This industrial pit furnace adopts a vertical deep-well furnace structure. Workpieces are loaded vertically from the top, effectively preventing bending and deformation at high temperatures.

Multi-Zone Independent Temperature Control, Uniform Temperature for Long Components

Multiple independent heating zones are set along the depth of the furnace chamber. Each zone can be set with its own temperature, effectively eliminating vertical temperature gradients. For long workpieces, it ensures consistent heating from top to bottom, resulting in excellent temperature uniformity.

Industrial Pit Furnace Multi-point Temperature Control

Precise Temperature Control, Excellent Process Reproducibility

Equipped with a PLC + touchscreen intelligent control system, the temperature control accuracy is ±1℃. It can store multiple process curves and monitor parameters such as temperature in each zone in real time. Historical data can be recorded and exported for easy process analysis and quality traceability.

Programmable Control, Fully Automatic Operation

Microcomputer program control, programmable curves, fully automatic heating/holding/cooling. Temperature control parameters and programs can be modified during operation, offering flexibility, convenience, and simple operation.

High-quality furnace lining for excellent heat preservation and energy saving

The furnace lining uses high-purity alumina fiber or mullite fiber materials, featuring a multi-layer composite insulation structure. It has low heat storage capacity, is resistant to rapid heating and cooling, and offers excellent heat preservation performance. The furnace shell temperature is ≤45℃, 大幅なエネルギー節約につながります.
