| titleOfInvention | Hot cutting method and apparatus for steel |
| abstract | PROBLEM TO BE SOLVED: To provide a fusing method and apparatus for removing and removing a surface layer of a steel material in order to remove flaws on a front surface, a back surface, a side surface and the like of a steel material such as a high-temperature steel material. . SOLUTION: A nozzle unit having a plurality of fuel gas and oxygen gas ejection holes arranged close to a steel material, and the surface layer of the steel material is cut while transferring the steel material. The ratio between the length of the slit provided between the oxygen jet nozzles at the contact portion and the length of the flow straightener satisfies the following formula, and the shape is such that there is no corner near the front end formed continuously with the base surface of the flow straightener. It is characterized by. X / L ≦ 0.30 to 0.75 where X: straightening body length L: slit length [Effect] Since the cutting oxygen is straightened along the straightening body, turbulent flow due to interference between adjacent nozzle units Can be prevented, and stable cutting can be performed without causing deep scouring marks generated on the surface of the slab after the cutting and, on the contrary, excessively high protrusions that are not cut. |
