　　In view of the structure of the steel is cut, generally refers to the industrial gas and oxygen mixed combustion and reach the requirements of cutting temperature, the steel structure of melting, slag and the process of segmentation. At present, the technology of flame cutting, water cutting, plasma cutting, CNC cutting, etc.. Is the most commonly used flame cutting, it has the advantages of low cost, simple operation, the mature technology, widely used characteristics, is the most widely used in the cutting techniques, refers to the natural gas flame cutting cut mixed with oxygen flame will the metal is heated to the melting point of steel by industry, and then release the high pressure oxygen the metal flow process and further violent oxidation of burning slag off the cut. Should pay attention to gas cutting:
鋼結(jié)構(gòu)氣割要點(diǎn)
(1) must check the equipment and tools for the whole cutting system all the normal operation before cutting, and ensure safety;
(2) gas cutting parameters should be chosen properly. When cutting, the shape of the oxygen jet should be adjusted so that it can reach and keep a clear outline;
(3) before cutting, removal of steel surface dirt, oil and rust and other debris, and in the following set aside a certain space, in order to slag blowing;
(4) cutting, must prevent tempering;
(5) to prevent cutting deformation, operation should be short side; first cut small pieces, cut off after the big; first cut complex, after a simple cut.
