EKİPMAN / BROŞÜR

HM31 is an inverter-based preheating and annealing unit especially for tubes. Setting, control and monitoring of HM 31 are carried out by the HeatMasters' Control System. HM31 is small and light in weight, which makes it easy to handle and transport. For power supply HM31 is connected to a mains current socket, which enables the use of short cables.

Programming
Using HeatMasters Control System, you can create and save an unlimited quantity of heat treatment instructions in the PC's memory and transfer them into the HM31 units. When the programming is complete, HM31 will carry out the heat treatment according to the instructions it has received. HM31's signal light indicates if any disturbances occur during the operation. A digital display on the front panel indicates the progress of the heat treatment. HM31 can be connected to long-distance monitoring.

Data registration
The unit registers the achieved heat treatment results in its memory, which makes it easy to prepare heat treatment documents. A separate temperature recorder is needed

Induction heats only the tube material, so radiant heat loss is very small. The maximum temperature with the induction method is around 700 °C. If a higher temperature is required, a heating resistor should be used.

Induction Heat Treatment with HM31
Operations to heat treat a tube maximum Ø140 mm:

Weld the thermocouple wire (max. 2 pcs) on the welding seam by using the thermocouple attachment unit HM250.
Cover the tube with thermal insulation and wind the induction coil around the workpiece to be heated.
Connect cables to HM31 and start heating.

Induction Annealing with two HM31 units
Large tube diameters and thick materials require two HM31 units for annealing. Two units are needed when the tube diameter exceeds 140 mm.
When using two HM31 units for annealing, the workpiece must have at least one measuring point for each unit.

Heat Treatment Resistors
HM31's power source is an inverter, enabling the use of even the smallest special resistors and the heating of very small workpieces. Technical data for the resistors are given in separate resistor brochures.

Heat Treatment Documents
Heatmasters system makes it easy to print heat treatment certificates, based on the data of the heat treatment results.
