Compact Hardening System HS 1

For small to medium-sized workpieces, tools and dies The HS 1 hardening system is used for pre-heating, annealing and tempering, hardening under inert gas, semi-vacuum hardening, oil hardening, austempering, carburizing and nitriding, ageing and brazing.

Information

Information

Basis for this compact hardening system is the HS 1 combitable

  • Stable combitable with shelf underneath for tools and accessories.
  • Integrated quenching grid for air-hardening steels or hot carburizing boxes, with fan for forced air cooling as option.
  • Heating hearth is assembled above the quenching grid for pre-heating parts for subsequent forging, welding, flame hardening, brazing etc. Heat reflective bricks included as standard.
  • Integrated quenching tanks incl. cover for water (stainless steel) and oil, incl. charging baskets and draining support. With heating element and thermostat for heating the water and/or oil bath.

The HS 1 combitable can be combined with a suitable hardening and tempering furnace.

Illustration of various processes:
Charging of the furnace with a workpiece. The workpiece is placed directly into the furnace or put into a carburizing box or onto the gas grid-system for charging.

Air hardening:
After heating, the workpiece can be placed onto the quenching grid for air-hardening. The fan provides forced air cooling.

Oil hardening:
Oil hardening can be performed in the oil bath provided at the side of the combitable. The hot workpiece is placed into the charging basket and lowered into the bath, then cleaned in the water bath. The water bath is also suitable for hardening unalloyed steels.

Case hardening and direct hardening:
The workpiece is packed together with granulate into a box for carburizing at 900 °C for several hours. Then the box is taken out of the furnace and set down on the quenching grid. After the cover has been removed, the workpiece is taken out and quenched in the oil bath.

Modular Hardening System HS 2

For medium-sized and large workpieces, tools, moulds and other parts The HS 2 hardening system consists of single components in modular design and can therefore be used in a wide variety of heat treatment processes, such as air-hardening, quenching in oil or water, martempering or hardening under inert gas. The system can be round off with cleaning tanks and components for post-hardening, tempering and annealing processes.

You can choose components to meet your particular requirements. The HS 2 hardening system can be enlarged at any time. All components have been proven in practice over many years, are reliable in operation and guarantee safe processes.
