Hardening is a heat treatment process used to increase the hardness and strength of metals, particularly steel. The process involves heating the material to a high temperature and then rapidly cooling it through quenching. Hardening enhances the mechanical and physical properties of steel, including its hardness, strength, and wear resistance.

Integral Batch Sealed Quench Furnace
Sealed Quench Furnace (SQF) is used for high-precision heat treatment primarily in auto components industry. This allows heat treatment for carbon steel to reach the desired hardness and strength. The furnace feature allows the materials to be processed in batches rather than continuous operation. HIGHTEMP is the leading manufacturer of Sealed Quench Furnace in India that provides a global clientele, with sales volume exceeding 500+.

Batch Furnace
HIGHTEMP offers advanced Batch Furnace solutions, designed to meet the specific heat treatment needs of various industries. Our Batch Furnaces provide reliable and uniform heat treatment for a range of materials, ensuring superior quality and durability. Our models include Roller Driven Batch Furnace, Two Tray Roller Hearth Carburising and Hardening Furnace, and Carburising and Hardening Furnace, offering flexibility and optimal performance.

Bogie Hearth Furnace
HIGHTEMP's Bogie Hearth Furnace is designed for the heat treatment of heavy and large components. Equipped with a bogie, the furnace simplifies the loading and unloading process, making it ideal for applications requiring precision and uniform heating. The insulation and efficient heating systems ensure energy savings while maintaining superior performance. This furnaces can be customized with single or double doors and single or double bogies to meet specific user requirements. Materials are loaded onto the bogie using an EOT crane or mechanical devices, and the loaded bogie is moved into the furnace via an electro-mechanical rack-and-pinion or rope-and-drum bogie drive mechanism, ensuring smooth and efficient operation.

Pit Type Hardening Furnace
HIGHTEMP's Pit Type Hardening Furnace is a reliable and robust heat treatment solution designed for the hardening process, which strengthens metal components by heating them to high temperatures followed by controlled quenching. Operating at temperatures typically ranging from 850°C to 950°C, this furnace ensures uniform heat penetration, making it ideal for long, cylindrical, or heavy components such as shafts, spindles, gears, and axles. The vertical, pit-type design allows efficient processing of components that require deep hardening while maintaining structural integrity. Widely used in automotive, aerospace, and heavy engineering industries, HIGHTEMP’s Pit Type Hardening Furnace delivers consistent results, durability, and energy efficiency, meeting the highest industry standards.
