摘要： A method for cutting steel includes heating a portion of the steel until it is molten, positioning a cutting torch to have a high angle of incidence relative to the molten steel, and blasting hgih pressure oxygen at the molten metal. The blast of high pressure oxygen further heats the molten metal and blows the molten metal away from the steel to create a cutting trench. The cutting torch is then moved generally parallel to the cutting method includes a cutting torch that emits a high pressure combustible gas and a high pressure combustion enhancing gas. The torch directs the high pressure gases at the steel so that the gases hit the steel at an acute angle of attack. An automated device propels the torch in the general direction of the desired cut. The resultant cut metal product has at least one edge with a grain pattern that is not perpendicular to the direction of cut.

摘要： The invention relates to a method for flame cutting a part made of a metal containing iron, implementing at least one blowtorch having a cutting nozzle, wherein the operation is carried out according to the steps of preheating a localized area of the part by means of a flame obtained by the combustion of a combustible gas and oxygen, then directing the gaseous oxygen towards the preheated localized area into a first pressure and/or first flow for initiating a bore while shifting the blowtorch in the cutting direction. Then, after initiating a bore in the part, the pressure and/or flow of gaseous oxygen is increased in the direction of the bore start area to a second pressure higher than the first pressure and/or a second flow higher than the first flow to obtain the complete bore in the part. The invention also relates to associated equipment.

摘要： A method is disclosed for removing material from moving metal workpieces, in particular for cutting sheet metal. It entails preheating, without melting, the surface of the workpiece to a temperature at which ignition is triggered by a combustible gas directed onto the preheated section as a jet under pressure, while burnt material from the workpiece is blown away from the cut recess thus produced. In order to achieve smooth edges on large-gauge workpieces with a relatively high feed-rate, a laser beam is also directed onto the cutting front in the cut recess.

摘要： The invention concerns a method for detecting the wear of a cutting nozzle on a cutting torch for cutting steel workpieces, in particular slabs, blooms and slugs. A branch line exits to the cutting torch in the feed line of the heating gas connection, into which branch line a neutral medium with a set pressure is blown through the cutting nozzle after closing the medium valves for heating gas, cutting oxygen and heating oxygen. To do so, said process is carried out once when installing a new cutting nozzle for the calibration thereof. Said process is performed again at set intervals, depending on the usage of the cutting nozzle, in order to determine and to store in memory the wear condition of the cutting nozzle and to generate an optical and/or acoustic signal in case a predetermined maximum admissible deviation amount of the medium blown in has been exceeded.
