摘要
This device comprises an oxygen-cutting torch (2) for heat-crack removal from a slab (3) having a longitudinal heat crack (4), the torch (2) being suitably inclined to the vertical and to the axial vertical plane of the heat crack; the device is equipped with a nozzle (6) for spraying a sheet of high-pressure water (7), which nozzle is combined with the torch (2) and is suitably inclined to the vertical and to the axial vertical plane of the heat crack (4) at angles such that the sheet (7) passes above the flame (1) of the torch (2) and strikes the slab (3) in the oxygen-cutting bath (8). The invention enables the formation of the fin, usually produced on the edges of the line of the flame (1) of the torch (2) and which, up until now, had to be removed manually, to be prevented. IMAGE
