OXY-HYDROGEN FLAME FOR CUTTING OF STEELS

摘要

The paper deals with oxy-hydrogen cutting of steel plates. The first part deals with calculation of the combustion efficiency of an oxy-hydrogen flame. A device for supply of a hydrogen-oxygen mixture is described. The main part of the paper is focused on oxy-hydrogen cutting and its advantages. The main conclusions show that the cut surface is flat and very smooth, the heat-affected zone is very narrow, and the cutting speed is relatively high.
