Thermal Hire

At the time of installation this plant has the largest capacity in terms of treatable component length in the UK. This complete turnkey heat treatment line is used by our customer for contract heat treatment. Transfer time for the load from furnace to quench is as low as 48 seconds, with the whole plant being PLC controlled from a single control room with no access to the working area being required by the operators during heat treatment or quenching. The plant layout is designed such that the bespoke pass-over charger does not have to travel laterally to transfer the load from the furnace to the quench therefore significantly reducing the time components are exposed to atmosphere, allowing better quenching and ultimately better metallurgical properties for the components.

Comprising of:

  • Two Heat Treatment Furnaces
  • Two Water Quench Tanks
