Tool Shop Hardening System KHS 17

Tool shop hardening system KHS 17

The work platform of the system is designed to carry an N 7/H - N 17/H series hardening furnace and NA 15/65 annealing furnace. Suitable protective gas boxes can be used. A movable oil/water bath for quenching and subsequent cleaning is positioned below the furnaces. This compact system is a practical solution is space is an issue. After heat treatment in the hardening furnace, the parts are removed from the furnace or the gas feed box and quenched in an oil quench bath or water bath. The charging basket can be used to move the part within the bath so that it cools more evenly. After quenching in oil the workpiece should be cleaned in the water bath, dried and immediately tempered in a forced convection furnace in order to optimally fix the mechanical components with regard to their strength behavior for the required conditions, minimize distortion and prevent potential flaws.

Tool Shop Hardening System MHS 17

MHS 17

The MHS 17 hardening system has a modular design and consists of a work platform for the heat treating furnaces, an oil bath for quenching and water bath for cleaning parts. As an option both baths can be delivered incl. heating. The baths are mounted to the left and right of the work platform and have charging baskets in order to induce even cooling of the parts in the bath. All parts may be ordered separately meaning the hardening system can be retrofitted or equipment added individually depending on the materials processed. The MHS 17 can have an air quenching system added to it for air-hardened steels. This platform has a powerful cooling fan to force cool the parts requiring hardening and also the gas feed annealing bag and holder. A refractory brick base is for placing hot boxes and workpieces on them. The quenching baths can also be fastened onto the forced cooling system. An additional storage platform can be integrated within the system for holding accessory equipment and/or optional charging accessories. Additional equipment see page 70.

Tool Shop Hardening Systems MHS 31, MHS 41 and MHS 61

These toolshop hardening systems are suitable for hardening larger components in air or under a protective gas atmosphere. The systems can be assembled from a chamber furnace, a forced convection furnace, a protective gas box with a gas supply via a solenoid valve, a charging plate to protect the furnace floor, and a quenching bath with heating element. During the heat treatment under protective gas, the process starts with the flushing of the batch in the protective gas box by means of protective gas. Subsequently, annealing is carried out in the chamber furnace at a lower process flushing rate. The chamber furnace is opened after the annealing process and the batch is removed from the protective gas box to be quenched in the preheated quench bath. The final annealing process takes place in the forced convection furnace. For easier charging, we recommend the use of optional charging aids such as pull hooks and charging trolleys. The toolshop hardening systems are an assembly of furnaces and accessories from our standard range. All components can also be ordered separately.
