Steel pipes cut and manufactured

machine HBM540A have got their work cut out for them. The blades normally have to cope with steel tubes of different qualities and a tensile strength of up to 750N/mm 2 . The tubes and rings produced by ‘Rohrunion Knauf’ are implemented in many different fields, stretching from the transportation of gases and water, to ship construction and crane construction, engine and steel construction, power plants and boiler construction, the chemical industry, apparatus construction and plant construction.” The plant at Voerde specialises in the production of seamless and welded tubes, steel pipes, precision steel tubes, high pressure lines, threaded tubes, boiler tubes, profile tubes and structural hollow sections. As a result of the wide cutting range of the large band saw, tubes with an exterior diameter of up to 800mm can be cut. It is therefore capable of dealing with the largest available dimensions of seamless rolled tubes on the market. The feed gripper can handle round material ranging from 30mm and has a clamping range of 1,000mm in width and 800mm in height. The machine is equipped with a bundle clamping device for the economic cutting of a number of tubes in one position or bundles of tubes. The maximum height of the bundles depends on the height of the drive wheel. The large band saw can be used in connection with bi-metal band saw blades as well as with carbide saw blades.

WITHIN the Knauf Interfer Group is Interfer in Voerde in the Lower Rhein area, an expert in the manufacturing of seamless boiler and welded steel tubes. When entering the production hall measuring nearly one kilometre two fully automated band saw cutting machines from Behringer GmbH Kirchardt are responsible for the cutting of all standard diameters and wall thicknesses quickly, precisely and reliably. “The Behringer machines operate nearly fully automatically, non-stop round-the-clock in our three shift working model,” stated Mr Werner Peters, the plant manager. “We have to be able to rely on our machines completely and this was one of the main reasons which led us to buy these sawing machines with their wide range of matured accessories.” “Up till now our saws have been too people and time-intensive. What previously had to be positioned by hand can now be carried out by the program- controlled machine allowing the machine to run problem-free throughout the night,” explains Mr Peters. During the late shift the machine is programmed to run smoothly at night. But also in the late shift the time saving advantages are clear to see. In the mean time the employees know exactly how long the machine can run without supervision and when it is necessary to refill the machine. The employees are then free to tackle other tasks. “The initial investment in the extensive automation has really been worth it,” said Mr Peters. “With a monthly throughput of up to 2,000 tons, the large band saw machine HB800- 1201A and the high-powered band saw Interfer GBS mit Menschen
