一、仿型气割的三大要素 1.氧气工作压力必须选择适当气割金属是由氧炔焰完成的。点燃的乙炔火焰当氧气压力调大时,火舌缩短。而当压力调小时,火舌伸长,也就是说氧炔焰带随着氧气压力的大小变化的,因此导至被气割金属燃烧带的尺寸亦发生变化。进一步讲也就是被燃烧的金属量也发生变化。这样一来气割完毕的断面的几何尺寸也不一样。当气割过程中,割枪嘴移动速度、割嘴与被割金属距离等参数选择适当,且不变的情况下,气割金属板燃烧带断面尺寸是:当氧气压力
First, the three elements of modeling gas cutting 1. Oxygen working pressure must choose the appropriate gas cutting metal is completed by the oxygen acetylene flame. Ignited acetylene flame When the oxygen pressure is increased, the flames shortened. When the pressure is reduced, the flare expands, that is to say, the oxy-acetylene flame belt changes with the pressure of the oxygen pressure, so the size of the flamed metal burning belt also changes. In other words, the amount of metal that is burned also changes. As a result of gas cutting section geometry is not the same. When gas cutting process, cutting torch moving speed, cutting nozzle and the distance between the cut metal and other parameters selected properly, and unchanged, gas cutting metal plate burning zone section size is: When the oxygen pressure
