• The oxygen lance method and the big acetylene-oxygen blow pipe method were studied. Both are the first trial in this country, so we started with making apparatus and arrangements. A 4 ton steel ingot was to be test-cut. The size of steel pipe for the lance, the gas (oxygen) pressure and consumption, the time required for cutting, etc. were studied. A blow pipe, of which the diameter was 11.5mm at the outlet, was designed and prepared, as well as the other necessary arrangement of the accumlator and leading arrangement of gas and other necessary attachments. The time, we could succeed in cutting a steel ingot of 107cm in thickness. In conclusion, the lance is easier to arrange the apparatus, but the manipulation is inferior to the blow pipe.
