氧-熔剂切割法是切割高铬和铬镍合金钢的常用方法。熔剂一般使用由铁粉、铝粉和其他配料组成的混合物。这些配料由于粒度大小不等,被氧流携带的速度也不同,致使这些成分进入切割区的浓度时高时低,影响了切割效率和质量。为了解决上述问题,苏联库兹湟佐夫冶金联合企业使用了一种新型的熔剂,其配方如下:铁粉56％、铝粉17％、环氧树脂18.9％、聚丙烯树脂2.97％、甲苯2.97％、聚乙烯胺2.15％。该熔剂经充分混匀后制备成粒度为
Oxygen-flux cut method is a common method of cutting high-chromium and nickel-chromium alloy steel. Fluxes generally use a mixture of iron powder, aluminum powder and other ingredients. Due to the size of these ingredients ranging from the size of the oxygen flow carried by the speed is also different, resulting in the concentration of these ingredients into the cutting area when high and low, affecting the cutting efficiency and quality. In order to solve the above problems, the Soviet Kuznetsov metallurgical conglomerate used a new type of flux with the following formula: iron powder 56%, aluminum powder 17%, epoxy resin 18.9%, polypropylene resin 2.97%, toluene 2.97 %, Polyvinylamine 2.15%. After the flux is fully mixed to prepare a particle size of
