Oxygen cutting is a method of using the heat energy of the gas flame to preheat the cutting place of the workpiece to the ignition point, spray out high-speed cutting oxygen flow, so that the metal burns and releases heat to achieve cutting. Oxygen cutting referred to as gas cutting, it has the advantages of simple equipment, flexible and convenient, good quality, etc. It is suitable for cutting scrap steel with larger thickness and longer size, such as large scrap steel plate, cast steel, waste boiler, scrap steel structure frame and so on. It can play a flexible and convenient role in the disintegration of scrap cars and old ships, and it is not limited by the narrow site or the size of the object, and can be operated in any occasion. In addition to the use of gas cutting processing of steelmaking charges, it is also possible to cut valuable plates, shapes, tubes and other materials from scrap steel for production. Therefore, oxygen cutting is one of the main methods of scrap steel processing, and it is widely used in the metal recycling sector. Common hand cutting uses 93% pure oxygen.
