In-House Heat Treatment Plant
Heat Treatment for Iron Castings
Heat treatment is used to alter the mechanical properties of cast iron, improving strength, hardness or wear resistance depending on the application.
Different processes are applied based on material grade and end use, ensuring the casting performs reliably once in operation.
The heat treatment of castings alters the microstructure of the material, thereby improving the component’s service life without changing its shape. CFL has always offered heat treatment as part of its services, and this has been done through subcontractors. We have now invested in our own Heat Treatment plant.
Our electric element ‘Top Hat’ furnace is operated from one of two halves. The maximum operating temperature is 1000 °C. Cycles are for Stress relieving, normalising, and annealing.
Exotherm controllers are used to program the cycles for these processes and to verify their effectiveness. Graphs can be downloaded to show the heat treatment process.
