PhoenixTM supplies biggest ‘Hot Box’ system yet to major steel wire manufacturer

A major steel coil manufacturer has taken delivery of a ‘hot box’ system to monitor the temperature of steel wire coils through their annealing process. This is the biggest system that PhoenixTM has built to date and has been engineered to fit inside a vertical steel coil as it travels through a continuous roller hearth annealing furnace. Weighing in at 500lb (225 kg), the system is built to withstand temperatures of 1470°F (800°C) for up 30+ hour’s duration, in a NX atmosphere. The system is able to monitor from up to 20 thermocouples placed within the coil, allowing full analysis of the heat treatment cycle on the Thermal View Plus software provided.

PhoenixTM system TS02-812-1 thermal barrier with Data Logger and Software

“The science behind ‘Hot Box’ systems is not difficult to understand” says Ian Budden, Director of PhoenixTM Ltd, “the longer and hotter the process, the bigger the thermal barrier has to be. However in this type of process system size may be limited by the internal dimensions of the wire coil it fits into, so barrier design and selection of the insulation materials is critical”.
