SOP-Series Mid-Frequency heaters of up to 630 kW

Series SOP mid-frequency billet heaters are designed for induction heating of steel billets with circular or square cross-section up to forging temperatures. The heaters consist of three modules – feeding, heating, and delivery. At the customer's request, the heater can be equipped with a hot billet sorter.

The heater is controlled programmable logic controller, available either as an Allen-Bradley or Siemens-based system, depending on the preference of the customer. The temperature of every processed billet is measured by a non-contact pyrometer. Its temperature value along with its time/date stamp can then be stored in the PLC memory. Heating and system control is performed via an interactive display panel and push-buttons which are connected to the PLC. Heater settings (desired temperature, power level, temperature range, employee login, etc.), are legibly displayed on-screen, and are modifiable to best suit the required task. Any heater system faults are also communicated to the operator via this display.

HEATING MODULE

The heating module contains:

MF capacitors
Cooling water system (optional left- or right-side placement)
Water-cooled busbars
Control modules/wiring for the heater and converters

MF capacitors

Inductor

The inductor is typically located on the top of the equipment frame. New mid-frequency input connectors and cooling-loop quick-connects facilitate minimized down-time in case inductor change-out is required. We can design inductors with a square or circular heating chamber. The inductor dimensions are available in range from Model series': 20, 25, 30, 45, 60, 80, 100, 120, and 130. Of course, inductors of other dimensions can be designed, built and delivered exactly to your specifications.

Feeding module - serves cold billets to the inductor
Delivery module - handles hot billet withdrawal
Hot billet sorter - sorts the hot billets based on temperature
