Together with Siemens VAI Metals today PRIMETALS, ABP Induction System GmbH has designed a new flexible system for heating rail heads.
A zone controlled induction heating device from ABP is used by SVAI. It compensates any axial temperature differences from the pre-process and exactly increases the rail head temperature for the heat treating. The specific requirements for heating are the high accuracy of the process and the wide range of possible rail types up to 75 kg/m.
Because of the fast and flexible controls of the new ABP technology, the temperature fluctuations are less than 20 Kelvin over 100 m long rails. With the same inductor set all rails – even asymmetric ones - can be heated with an extremely high efficiency.
Installation of the system was carried out at Baotou Steel in Inner Mongolia and was successfully completed in the shortest possible time.
