Stress Relief Furnaces

Stress Relief Furnaces relieve stresses in materials generated by welding, machining, or heat processing.

The purpose of a Stress Relief Furnace is to raise the temperature of a component to slightly below the transformation temperature. This elevation in temperature eliminates internal stresses caused by secondary processes such as welding, machining, or cold forming. Upon reaching completion of the heat-up and hold cycle, the parts are then cooled at a controlled rate.

Stress Relief Furnaces relieve stresses in materials generated by welding, machining, or heat processing.

The purpose of a Stress Relief Furnace is to raise the temperature of a component to slightly below the transformation temperature.

Each Industrial Furnace project undergoes a comprehensive evaluation of every production requirement. The assessment includes areas such as production goals, part configuration and construction, part mass, temperature profile, and facility location or elevation.

Features

  • Economical operation is achieved with superior thermal process engineering practices that apply state-of-the-art insulation material, airflow management, and custom programming.
  • Recirculation fans with high efficiency motors to reduce energy consumption.
  • Recirculation ductwork designs provide precise airflow to specific areas of the product resulting in smaller foot print ovens thus reducing utility and factory space costs.
  • High-efficiency (gas or electric) heat sources to reduce energy costs.
  • Robust structural oven frames and component supports.
  • Application specific insulation materials are selected to provide optimum insulating characteristics and long term energy savings.
  • Design considerations for easy access to process areas and oven components.
  • Private labeled and purchased components meet UL, UR, and CE standards.
  • Programmable controllers with HMI (Human Machine Interface) displays allow for user friendly operation and machine diagnostics.
  • NEMA style control panels.
  • Factory tested to ensure on time delivery and field start up.
