Vertical dual-frequency induction hardening machines
Custom-engineered turnkey solutions for induction hardening, tailored to the specific requirements of the client
Salus dual-frequency induction hardening machines provide deep penetrating heat and made it possible for our clients to launch a new generation of induction-hardened large rolls (hardening depths up to 60 mm), also HSS rolls. The whole induction hardening process is automated and computer controlled. These machines also enable the rehardening of used rolls and the preheating of rolls. For improving the quality of the hardened layer after the induction hardening, we designed the cryogenic freezers for sub-zero treatment.

BIKS 830 Vertical dual-frequency induction hardening machine
- This induction-hardening machine is for inductive surface hardening of rolls with a diameter from 250 to 830 mm.
- Induction frequency is continuously variable and therefore several case depths are possible, up to 60 mm. The machine has two inductor coils, which operate simultaneously, each with its own frequency, one with a high frequency (250 Hz – 1000 Hz) and another with a low frequency (50 Hz -100 Hz) and thus a longer period of hardening is enabled, more power is delivered and larger hardening depths are achieved.
- The machine also enables the rehardening of used rolls and the preheating of rolls (before that the water must be transferred from the upper to the lower tank).

BIKS 750 Vertical dual-frequency induction hardening machine
- This induction-hardening machine is for inductive surface hardening of rolls with a diameter from 250 to 750 mm.
- It is another SALUS dual-frequency arrangement using two different power suppliers and two different frequencies to achieve the desired hardness profile of large and massive rolls where larger case depths are necessary.
- The induction hardening process is automated - computer controlled process. Different sensors, settings of parameteres and automation ensure the reproducibility and accuracy of the hardening process.
- Roll manipulation: rolls are uploaded and lifted on wagons (which are placed on a platform) in a horizontal position by a forklift or crane. Lifting of rolls is carried out with the upper yoke of the machine.
Product category: Cooling equipment
Cryogenic freezer
The cryogenic freezer is designed for improving the quality of the hardened layer after the induction hardening. The sub-zero treatment (cooling temperature of -150˚C) of hardened large rolls is used to complete the transformation of the steel microstructure from austenite to the stronger and harder martensitic structure, to provide a uniform distribution of the martensite, a uniform hardened surface (no soft zones, no pitting) and the material’s greater hardness (additional + 2 HRC) and wear resistance. The rollers are cooled with liquid nitrogen, using jets and fans.
The chamber is equipped with:
The chamber is equipped with:
- a PLC controller and an operating panel with a touch screen that enables all parameters to be monitored, all the settings to be changed etc.
- a fan for air circulation (controlled by a contactor)
- a valve to add cold gas
- hydraulic opening/closing of the cover
- heaters for heating the chamber (power 25 kW)
- seal heaters (special version with electric heated seals)
Quench tanks
Custom-made quench tanks are tailored to the metal parts to provide uniform cooling and quenching which is enabled through appropriate tank construction and sufficient agitation close to all surfaces of the parts.
Each quench tank is equipped with agitators, mounted at an angle to ensure better circulation, besides the necessary sufficient agitation close to all surfaces of the large parts to break the vapour film around them. Pumps supply a cooled medium to the pool at an angle and under pressure, contributing to further circulation and agitation of the media.

Automated quench hardening station
Entire quench hardening station for 6-metre-rolled profiles
The station consists of:
The station consists of:
- a quench tank and agitators
- roller conveyors driven by an electric motor
- automated racks for profiles (for safe and soft lay-down of profiles)
- automated protective clamps which prevent rolled profiles bending during quenching (minimal deformations)
- a 2 x 50 m3 tank with two different hardening media
- an automated pumping system
- heat exchangers, and
- a Siemens controller
