What is a Solution Heat Treatment Furnace?

Heat treat furnaces are used for the production of various industrial alloys. The solution of heat treatment furnace is a trending procedure for developing alloys by heat treating the metals. The alloy is heat treated to a temperature where it melts but does not precipitate, hence yielding the strength of the alloy to increase. The furnace is particularly built by expert solution furnace manufacturers that are controlled by Microchip panels for better control over the solution heat treatment process.

A multitude of alloys is run through the process of solution heat treatment to change their characteristics for better industrial purposes. Various elements are used together to treat the alloy in a solution heat treatment that ranges from using increased temperature and solution state age precipitation.

What happens in a Solution heat treatment furnace?

Most alloys become work-hard when they are made in plants. It poses a challenge in using the alloys for further processing. Treating the alloys with solution heat treatment reduces the work-hardening, and makes these alloys more usable. The hardening process, brazing, coating or welding ill-treats the alloys, and result in early precipitation stages that may not be as strong as desired for various applications.

Development of the final material properties required to satisfy part specific design criteria typically requires the material (casting/wrought material) to be subjected to a long lower temperature heat treat cycle to develop an alloy specific microstructure through precipitation age hardening. When we talk about the manufacturing process, the solution of heat treatment is the final step; as following this, the alloy goes into machines for manufacturing processes.

The process of solution heat treatment

The solution heat treatment is a process that requires high-temperature treatment ranging from 1800 to 2450°F that too in a vacuum, created artificially. The solution furnace manufacturers keep the special provision of creating high-temperature, vacuum that is followed by fast-paced gas fan cooling down to room temperature. The temperature is used as per the specific alloys so that the desired hardness is achieved.

The process that follows heat treatment is precipitation age hardening. The solution of heat treatment furnace is very economical and efficient to achieve alloys with less work-hardening, making it usable as per the required industry standards. The solution furnace manufacturers provide the equipment that is capable of performing high-end heat treatment, offering vacuum and inert state, airflow under control for better solution treatments. The optimization of machinery leads to the usage of recirculation in airflow using ducts. The airflow is made precise by defining its directions and reducing the energy costs of the entire process. The industry applications of the treated alloys range from the below industries:

  • Aerospace or Aircraft manufacturing
  • Agriculture equipment development
  • Automotive parts development
  • Aluminum Casting
  • Forging
  • Military equipment building
  • Mining equipment development
  • Vehicle development

The heat treatment level, vacuum creation, and precipitation vary from alloy to alloy and the furnaces are custom designed to deliver right operational circumstances. The heat sources used for the furnace may vary from manufacturer to manufacturer. They will also depend upon the alloy being treated and the options can be electric or natural gas. These two options make temperatures more controlled.
