Abstract

1. A burner for the thermochemical separation or desurfacing of thick steel workpieces of a thickness of from 150 to 600 mm by means of an oxygen lance, the burner mainly comprising a nozzle holder (3) and a nozzle (1) formed with a cutting oxygen entry bore (13), a nozzle bore (11) and a cutting oxygen exit bore (12), characterised in that the nozzle bore (11) is shaped cylindrically over its length of between 0.5 and 10 mm and has a diameter of from 1.5 to 3.6 mm and the transition (14) from the oxygen entry bore (13) to the nozzle bore (11) is sharp-edged.
