Multi-Zone Temperature-Controlled Pit Furnace

Multi-Zone Temperature-Controlled Pit Furnace (High-Uniformity Electric Pit Furnace)

The multi-zone temperature-controlled pit furnace is a vertical high-temperature resistance furnace designed specifically for large workpieces, high-precision heat treatment, and high-uniformity sintering processes. The equipment utilizes multi-point temperature sensing, independent control across multiple zones, and integrated distributed control technology. By coordinating three temperature control points and nine independently regulated zones, it achieves precise adjustment of the internal temperature field, effectively resolving the issue of vertical temperature gradients often found in deep-chamber pit furnaces.
Characterized by excellent temperature uniformity, an intelligent control system, and an energy-efficient furnace structure, it meets a wide range of process requirements, including sintering, recuit, traitement thermique, calcination, and high-temperature experimental work.

Caractéristiques du produit

1. Multi-point zonal temperature control with excellent uniformity

This equipment utilizes integrated multi-channel synchronous control technology, featuring three temperature control points and nine heating zones to ensure uniform temperature distribution within the furnace chamber. Temperature uniformity is maintained at ±1°C within an 800mm diameter range and ±5°C within a 1300mm height range. It is particularly well-suited for the vertical heat treatment of long or large-sized workpieces that demand strict temperature uniformity.

2. Large-capacity furnace chamber with superior processing capability

The usable furnace dimensions are 800mm in diameter and 1500mm in height, providing a total volume of 0.75 cubic meters. The deep-pit design accommodates the vertical heat treatment of workpieces with high length-to-diameter ratios—such as rods, tubes, and long shafts—allowing for the processing of multiple batches or large-sized components in a single run.

3. Integrated multi-channel synchronous control for precision and reliability

By employing an integrated multi-channel synchronous control system, three control points and nine heating zones work in coordination to achieve precise temperature regulation and uniform distribution within the chamber. This ensures high temperature control accuracy and excellent process repeatability.

4. Programmable control and fully automated operation

Featuring microcomputer control for ease of use, the system allows for programmable settings regarding heating, holding, and cooling curves, enabling fully automated operation. The heating rate is adjustable between 1°C/min and 20°C/min, meeting the specific heating speed requirements of various materials.
