• Economical Gas Cutting on the Basis of Drag Length

抄録

The most important problem in oxy-acetylene gas cutting practice, is related to the consumption of oxygen and acetylene, i. e., economical use of gas. It has been generally said and understood that drag length brings the lower consumption of both.<BR>The writers tried to analize this problem by investigating drag length on the cutting sections of mild steel having the thickness of 12, 19, 25 and 32mm respectively under various oxygen pressures and at different cutting speeds.<BR>The results are as follows :<BR>(1) Drag length should be standardized at 15 to 20% of the thickness of steel plate.<BR>(2) To keep drag length standard, the proper values of oxygen pressure as swell as cutting speed shuld be applied, varying in accordance with the thickness of the plate.<BR>(3) Cutting sections are obtained with the most beautiful and smooth surface by the above-mentioned operation.<BR>(4) Consumption of oxygen per unit area is about 55% as compared with that of the case when drag length is zero.
