SEAM ANNEALING SYSTEMS
Seam annealer systems ranging from 300 kW to 2500 kW in modular design. The ideal power distribution, depending on tube speed will result in an optimum seam treatment being achieved by mean: of single and multiple annealing (Q&T). The annealing speeds are adapted to the welding process, the correct frequency selection guarantees low differences in temperature (internal/external) Control and monitoring is effected by means of PLC-control and controlled positioning axes.
The screen shows all control parameters. The guidance of the inductor - i.e. seam tracking - can be effected either manually or full automatically.
SNG PERFECT THROUGH:
The high life time of the inductor
The ELOMAT-frequency converter's high degree of reliability
The low degree of maintenance required
The high level of process reliability due to advanced technical competence
AN ALL-AROUND ANSWER FOR TUBES
Induction and conduction heating of tubes are keys to increase productivity and quality assurance.
HF seam welding for tubes and shaped sections, MF seam annealing, induction tube heating for a range of subsequent processes such as sizing, tube bending, tempering, coating etc. are key aspects of this technology. A decisive factor in the manufacturing of tubes is the precise matching of all the machining processes to each other.
This is where SMS Elotherm's experience and skill come in.
