Heat Treatment Furnaces and Furnace Control Systems
Burners with good turn-down characteristics are required for this application, as the temperature has to be accurately controlled during the ramp-up, soak and cooling periods of the cycle. This is achieved in the continuous system by controlling the temperatures in the various zones through which the material passes. The control system for these furnaces is typically equipped with temperature recording devices so that a record of the temperatures to which the material has been subjected during heat treatment can be supplied to the customer for the QA data pack.
Typical customers where The Combustion Group has been involved in these types of furnaces are Mittal Steel, SCAW Metals and Columbus Stainless Steel.
