High Temperature Furnace: Advanced Heat Treatment for Extreme Industrial Applications

In the field of industrial processing and materials science, precision heat treatment at extreme temperatures is often essential. Whether it’s for sintering, ceramic processing, metal heat treatment, or material testing, a high temperature furnace plays a crucial role. Designed to operate beyond conventional temperature limits, these furnaces are capable of delivering consistent performance at temperatures up to 1800°C or higher, depending on the material and application.

At JR Furnace & Ovens, we engineer high-performance high temperature furnaces with advanced materials, robust construction, and cutting-edge control systems to meet the toughest demands of modern industries. Our solutions are customized for laboratories, research institutions, and production environments where accuracy and reliability are non-negotiable.

What is a High Temperature Furnace?

A high temperature furnace is a type of thermal processing equipment designed to heat materials to extremely high temperatures—typically above 1000°C and up to 1800°C or more. These furnaces are built with special refractory linings, high-grade insulation, and heating elements made from materials like silicon carbide (SiC), molybdenum disilicide (MoSi2), or graphite.

They are used in both batch and continuous processing and can be configured for:

  • Atmosphere-controlled processing (inert gas, vacuum, reducing or oxidizing atmospheres)

  • Lab-scale or industrial-scale applications

  • Horizontal or vertical loading

  • Manual or automated operation

Difference between Process Annealing and Full Annealing

A quick comparison between process annealing and full annealing of steel  Process Annealing Steel warmed underneath the basic temperature, save it at that temperature for while then cooled gradually. Likewise called subcritical annealing. Reasonable for low carbon steel  Stage change not engaged with this process. The material is in a similar stage in all through the process.  process annealing is less expensive than full annealing.  Utilized in sheet metal and wire enterprises.  Full Annealing Heat eutectic steel 30 to 50 °C over its basic temperature, save it at that temperature for while then gradually cooled down. Appropriate in low mild steel just as in high carbon steel.  Stage change happened during the Full annealing process. The resulting crystal structure is laminated perlite. Come about metal is more ductile, and this process is utilized in steel for deep drawing operation. Get Complete Custom Engineered Solutions in various capacities to meet th...
