steel cutting

Steel structure cutting refers to the process of cutting steel structure according to the needs in industrial production. For the steel structure to be cut, it generally refers to the process of melting, slag blowing and segmentation of the steel structure when the industrial gas and oxygen are mixed and burned to meet the cutting requirements. At present, the technologies used include flame cutting, water cutting, plasma cutting, numerical control cutting, etc. The most commonly used is flame cutting, which has the characteristics of low cost, simple operation, mature technology and wide use. It is the most widely used cutting technology in the industry. Flame cutting refers to the use of industrial gas and oxygen mixed combustion flame to heat the cut metal to the melting point of steel, and then release high-pressure oxygen flow to further oxidize the metal and produce molten metal The process of slag blowing off to form a notch. At present, the main cutting gases used are acetylene, propane, hydrogen, oxygen, Xiapu gas, natural gas, etc.
