为适应生产发展需要和发展我国割嘴的新品种,我厂在上海焊切工具厂配合下,先后研制了切割氧压力为8公斤/厘米~2的射吸式氧-乙炔和氧-丙烷双切割氧孔割嘴。现将这种割嘴的切割原理、割嘴的结构及切割性能作一简单介绍。一、双切割氧孔嘴的基本原理影响钢材氧气切割过程的主要参数是切割氧流和钢材的温度。要提高钢材的切割速度和切口面质量,就必须提高切割氧流的出口速度和钢材的温度,本割嘴就是以先行一股切割氧流进行粗切,利用其放出的热量加热钢材,为后行的一股氧流创造
In order to meet the needs of the development of production and the development of new varieties of cutting mouth, I plant in Shanghai welding and cutting tool plant with the cooperation, has developed a cutting oxygen pressure of 8 kg / cm ~ 2 jet suction oxygen - acetylene and oxygen - Cutting oxygen hole cutting nozzle. Now this cutting tip cutting principle, cutting the mouth structure and cutting performance for a brief introduction. First, the basic principle of dual-cutting oxygen nozzle The main parameters affecting the oxygen steel cutting process is cutting the oxygen flow and the temperature of the steel. To improve the cutting speed and cutting surface quality of steel, it is necessary to improve the exit speed of the cutting oxygen flow and the temperature of the steel. The cutting nozzle is used to rough cut the first oxygen flow and use the heat released to heat the steel, A stream of oxygen created by the line
