BLM - Billet / Bloom Linear-cutting Machine
GEGA strand torch cutting machines convince with high cutting quality results as well as a solid and reliable design. The BLM type operates with linear cutting torches and is suitable for wide billets and blooms (also rounds and beam blanks) in continuous casting plants.
The torch cutting machine is clamped to the strand thus driving synchronously with the strand in casting direction. During the movement, the cross-cutting of billets is carried out by linear torches. After completion of the cutting process, the clamping is detached and the machine is driven by motor contrary to the casting direction into start position. The cutting cycle starts again after receiving the signal for the next cycle. Driving of the machine over the rear axle is carried out by a frequency controlled AC motor with a one-step spur gear and brake. A frequency controlled AC motor drives each linear torch. The granulation is carried out by means of granulation nozzles, which are arranged on one side of the machine.
GEGA‘s BLM torch cutting machines consist mainly of a water-cooled machine main frame with an exchangeable and water-cooled bottom plate against the radiant heat of the strand, a maintenance lid, a clamping system, the inner components, two guide wheels, travelling wheels and a cable tray. All components such as bearings, drives, valves, cylinders etc. are inside the water-cooled housing and have an optimal protection against the radiant heat.
