摘要： PURPOSE:To restrain and prevent the generation of the fin due to the scarfing work, by injecting the incombustible gas or the air to both sides of the jet stream of the scarfing oxygen so as to form the gaseous mixture; and to make possible the scarfing breadth to be selective width, by arranging plural sets of the tip in the direction of scarfing breadth. CONSTITUTION:By selecting the tip A, the inert gas or air, for preventing generation of the fin, is fed from the paths 25, 26, to the chambers 11, 12, and is injected from the injection nozzles 18, 19, through the pipe path 15. The scarfing oxygen is fed from the path 22a to the chamber 8a and is injected from the scarfing oxygen injecting nozzle 23a through the path 24; hereby, the purity of oxygen on both sides of the oxygen stream is reduced, so that the soarfed plane free from sticking of the fin due to the tip A can be obtained. In case of the scarfing of wide breadth, the tips A, B, etc., are selected, and the gas for spreventing the generation of the fin is injected from the injection nozzles 18, 20, and the scarfing oxygen is injected from the injection nozzles 23a, 23b, etc., and the injection nozzle 19, and the scarfed plane free from sticking of the wide fin can be obtained.

摘要： PURPOSE:To remove efficiently and exactly a cut slag by gas blowing, by driving a two-piece set of torches from both ends, executing gas cutting by making reverse side nozzles correspond to each other, and thereafter, moving one reverse side nozzle faster than the cutting speed. CONSTITUTION:A two-piece set of cutting torches 21, 22 are moved in the direction approaching each other from both ends of a slab cutting intended line. In this case, gas cutting is executed by making reverse side nozzles 51, 52 correspond to each other while blowing gas whose O2 dinsity is >=50%, and removing a cut slag. Also, after the cutting is completed, the gas pressure is increased to one - five times while moving continuously one reverse side nozzle 51 along the cut groove at a speed tow -20 times the cutting speed, by which the cut slag is removed. Thereafter, the gas pressure is decreased to 1/3- one time the blowing gas pressure at the time of cutting, and gas blowing is executed. It can be prevented exactly by this post-blowing treatment that a slag is left around the center part of a steel material whose cutting is ended.

摘要： PURPOSE:To reduce the oxygen purity on both sides of the jet stream of scarfing oxygen on purpose to prevent sticking of the fin on both sides of scarfed zone, by simultaneously injecting air or incombustible gas from both sides of the injection port fot the scarfing oxygen at the scarfing tip. CONSTITUTION:The scarfing oxygen is injected from the injection port 7 being supplied from the chamber 4 through the path 6. Air or the incombustible gas is supplied from the chamber 5 through the path 10, and is injected from the injection port 11 communicated to the oxygen injection port 7; hereby, air or incombustible gas is mixed with the oxygen jet stream nearby the tip of the injection port 7, and the oxygen purity over the injection breadth of the scarfing oxygen is reduced. This air or incombustible gas for preventing the fin is injected at the injection pressure 1.0-4.8 times of the oxygen injection pressure, and the injection angle is 0-5 degrees inclined inward. According to this method, the fin to be generated by the scarfing work does not stick to both sides of the scarfed plane, so that the removing work for the fin at the later process becomes unnecessary.

摘要： PURPOSE:To obstruct the outflow and scattering of the molten steel flow into the lateral and obliquely forward directions, by blowing the gas for preventing the generation of fins, etc., against not only both sides of the surface to be blown with the scarfing oxygen, in the surface of the material to be worked, but also the obliquely forward portion. CONSTITUTION:The gas is blown against both side portions FB, FB, of the surface FA to be blown, of the material Y to be worked, from the injector nozzles 13, 13, for the gas to prevent the generation of the first fin, etc.; hereby, the outflow of the scarfing gas stream A is obstructed; and the gas for preventing the generation of the second fin, etc., is blown from the injector nozzles 14, 14, against the obliquely forward portions FC, FC, of the surface FA to be blown; as a result, the scarfing oxygen stream A and the gas stream B for preventing the generation of the first fin, etc., are obstructed so as not to flow obliquely forward from the tip corners X3, X3, of the surface X to be worked by scarfing. The injection angle gamma of injector nozzles 14, 14, is settled in a range 10-25 degrees, and the ratio (gamma/alpha) of the angle gamma against the injection angle alpha of the scarfing gas injector nozzle 12 is settled in a range 0.4-0.7.

摘要： PURPOSE:To remove the slag sticking to nozzles during cutting and to improve the life of the nozzles by moving two cutting torches in the direction where the torches approach to each other and replacing the preheating flame to be blown together with the gaseous oxygen of the rear nozzle facing one torch which is retreated just prior to completion of cutting with an inert gas. CONSTITUTION:Ejection of gaseous oxygen is continued with a rear side nozzle 52 facing a torch 22 to be retreated during the course of cutting in one way as the final stage of cutting and an inert gas is ejected in place of a preheating flame. The nozzle 52 on the retreat side during the process for cutting in one way is thus less covered with the slag formed by blowing from the nozzle 51 on the other side and the clogging of the hole for ejecting the preheating flame is prevented. The oxidation combustion force of the gaseous oxygen from the nozzle 52 is weakened by the ejection of the inert gas and the rear surface of a steel material 1 is prevented from flawing.

摘要： PURPOSE:To obtain the cut surface to which no dross adheres by performing piercing to a cutting material, and cutting it by forming at least one closed circuit between its position and a graphic which becomes a product. CONSTITUTION:A dross-free speed range in which no dross adheres in accordance with plate thickness of a cutting material exists. As for this speed range, the dross-free speed range is wider in the case of executing a running start from the end face of the cutting material than in the case of executing a piercing start from the surface of the cutting material. In this state, piercing is performed to a prescribed position 3 on the cutting material 1, the position 3 is set as a start position of cutting and a closed circuit 4 is formed between the position and graphic 2, and by allowing it to intersect with a cut groove 6 which is cut already in an intersection 5 of this closed circuit 4, notching by a running start method in which the cut groove 6 is an end face of the cutting material 1 is executed. In such a way, a continuous adhesion of a dross is cut off, and a product to which no dross adheres can be obtained.
