Induction Heaters from simatec
For a quick warm-up of roller bearings and other ring-shaped metal parts. Thanks to the heat extension, the work piece can easily be fitted onto the shaft. In the warm-up process, only the work piece is heated but the equipment itself remains cold. Simatec manufactures induction heaters for work pieces from 20 to 4'000 kg. Heaters for special applications are developed on demand.
The inductive warm-up of ring-shaped parts is a quick, clean and efficient method. It replaces traditional warm-up techniques such as hotplates, hot oil baths, open flames or stoves. |

The introduction of induction heating systems in rolling processes is common among the most qualified producers of hot rolled steel sections. The main advantage linked to the use of an induction furnace, in the different parts of the roll train, is temperature control for different materials and different dimensions.
In fact, thanks to the absence of the thermal transistors of the application, and to the high value of specific power density per unit of volume, rapid responses in time of delivered power are possible, allowing to obtain the heating profile desired.
Generally, in the sector of hot rolling, bars are usually heated through intermittent passages. This increases the average temperature before intermediate forging or final machining, and allows to compensate the irregular head – tail temperature, making it possible to increase the system’s productivity by reducing gas consumption, as well as wear of the main furnace’s refractory material. Furthermore, it’s possible to carry out rapid changes in production while maintaining temperature control within common industrial standards, and reduce the number of defects due to temperature irregularity.
Induction is also present on the market with static heating operations for bars subject to subsequent hot rolling, allowing flexibility in production changes even with small lots of material, along with other advantages such as reduction of superficial decarburization even with atmospheric heating, elimination of ordinary maintenance costs of the gas furnace, and elimination of localized overheating in the combustion area. |
