The device may be used in descaling, testing, oxygen cutting or surface treatment techniques.
A camera (32) is arranged to map defects in the molten metal bath formed by scarfing using a scarfing torch (34) on a steel slab (37).
It can be followed by a scarfing installation automatically cutting along the detected defects.
Said abrasive grains are used in particular for making grindstones, in particular designed for scarfing stainless steel.
As a result, an amount of scarfing of a cast piece is greatly reduced and no carbon pick-up occurs.
Disclosed is an apparatus for scarfing a steel bar by blasting a fuel gas to the steel bar.
At least one granulating nozzle (14) installed close to the scarfing burner (5) is used to remove by granulation thus produced melted steel and slag, traverse to the vertical.
A scarfing torch (100) comprising a plurality of vertically aligned nozzles (110, 111, 112) with respective outlets (140, 141, 142) in a common outlet surface (125).
Additional drive rollers (10.2) transport the workpiece (2) after scarfing to a subsequent deposit device (13) for depositing the workpiece (2) on one of its wide sides on an additional line of rollers (6.2).
