Hardening Furnace & Applications
Hardening is the process of heat treatment in which steel is kept at a suitable temperature till it gets transformed into austenite and then quenching it rapidly.
Based on the carbon content present in the steel, the temperature for austenitizing is decided. By increasing the heating time, the core gets completely transformed into austenite. The final microstructure of the hardened steel would be ferrite or martensite.
Parts, where core hardening is specified, shall be tempered at a temperature not less than 280°C above the nitrocarburizing temperature. In the process of metal hardening, the mechanical properties of the components are imparted to make it fit for use.
Hardening Furnaces by Therelek
Pit Type High Temperature Furnace
Pit type sealed retort furnaces are of a cylindrical design vertically erected with a positive sealing mechanism on top in order to contain and preserve heat and atmosphere during a process cycle.
Horizontal Vacuum Furnace
Our Horizontal Vacuum Furnace has cold wall construction with metallic/graphite hot zone. The door swivels sideward and the material is loaded from the front.
Vertical Vacuum Furnace
Therelek’s Bell furnace is designed with optimal performance for high sensitivity and delicate components.
Sealed Quench Furnace
Therelek’s Sealed Quench Furnace line consists of preheating and tempering furnaces, washing machines, stationary table, hydraulic lifts and charge transfer systems
Continuous Mesh Belt Furnace
A multi-zone control environment is present in a continuous high-temperature furnace, often with a single pre-heating zone,
Chamber Furnace
Therelek’s chamber furnace can operate up to 1800°C. These furnaces are usually rugged, refractory based construction
Roller Hearth Furnace
Roller hearth furnaces are designed for continuous production and easy maintenance to handle large size and weights
Bogie Hearth Furnace
Our standard bogie hearth furnace goes up to 1500°C, however, we make custom designed furnaces for any special requirements
