丙烷快速切割原理快速切割要求在单位时间内加速切割点的金属达到燃烧温度并使其燃烧过程快速进行,同时增强清除氧化熔渣的能力。因此,必须强化予热火焰,提高切割氧的流量和动量。为此,把予热孔增加到21只,分内外两层,均匀分布在切割氧孔的周围,以缩短切割点予热时间,提高表面起割速度。另外把切割氧孔道做成扩散型,并将切割氧的压力提高互17公斤/厘米~2,使切割氧流在孔道出口处的流速达到2.5马赫(即2.5倍音速)左
Propane Fast Cutting Principle Rapid cutting requires that the metal accelerating the cutting point per unit of time achieve a combustion temperature and allow for rapid combustion while enhancing the ability to remove oxidized slag. Therefore, it is necessary to intensify the heat flame and improve the flow rate and momentum of cutting oxygen. To this end, the pre-heat hole increased to 21, points inside and outside the two layers evenly distributed around the cutting oxygen hole to shorten the cutting point to pre-heat time and improve the surface cutting speed. In addition, the oxygen channel is made diffused, and the pressure of cutting oxygen is increased by 17 kg / cm ~ 2 so that the flow rate of the cutting oxygen flow at the exit of the orifice reaches 2.5 Mach (ie 2.5 times the speed of sound)
