Abstract

PURPOSE: To perfectly remove slag without producing treating residue of slag and deep digging, by ejecting oxygen so as to be enclosed by the preheating flames in oxidation-removing the slag produced at the gas cutting of a steel material by oxygen.
CONSTITUTION: In cutting a steel material 1 by a gas cutting method using a cutting torch 2, the slag 3 adhered on the under surface of the cutting part is oxidation- burned by the oxygen ejected from slag treating nozzles 4 and is thereby removed. In this case, the oxygen flow 6 is so ejected as to be enclosed by preheating flames 5, to prevent the pressure thereof from decreasing, thus the slag 3 is perfectly removed by effectively using oxygen. At this time, the angle θ1 of the nozzles 4 to the steel material 1 is set at 5W10°, the angle θ2 of the nozzles 4 to the cutting center line 7 at 5W15°, the distance between the center line 8 of the torch 2 and the intersection of the center line of the nozzle 4 and the steel material 1 at L1 and the pressure of the oxygen 6 enclosed by the preheating flames 5 at 0.15W0.5kg/cm2.
