西格马低温井式炉

低温井式炉为洛阳西格马高温电炉生产的低温炉，低温井式炉工作温度高达650℃。井式空气循环炉安装在地面或正上方。

这些熔炉通常用于有色金属合金的热处理、淬火后的回火、焊接和成形后的应力消除，以及时效处理。

由于在这些温度下，对流是传热的方式，所以在蒸馏器内提供空气循环，以保持稳定的温度均匀性。这些熔炉也适用于基于控制气氛的工艺。

Low-Temperature Pit Type Furnace by Sigma

Pit type air circulation furnaces are installed with the opening at ground level or just above it. These are low-temperature furnaces with operating temperatures up to 650℃.

These furnaces are usually used for the heat treatment of non-ferrous alloys, tempering of ferrous alloys after hardening, stress relieving after welding and forming, also for ageing.

Since convection is the mode of heat transfer at these temperatures, air circulation is provided inside the retort to maintain stable temperature uniformity. These furnaces are also suitable for controlled atmosphere based processes.
