在球铁生产中,由于原材料供应不够理想,使用的燃料、铁料都较低劣,球化处理工艺还不很完善,因此产品质量不稳定,废品率高,球化剂消耗量大,材质性能水平偏低等是较普遍的现象。如能在炉前及时地测知其内在质量或技术性能,则可弥补上述条件的不足,及时采取挽救措施。因此在球铁生产中人们一直在探索简便而又准确的炉前快速检测方法。 In the ductile iron production, due to the unsatisfactory supply of raw materials, the fuel used, the iron material are inferior, the ball treatment process is not perfect, so the product quality is unstable, the rejection rate is high, the nodular agent consumption, material properties Low level is a more common phenomenon. If in the furnace in time to detect the inherent quality or technical performance, you can make up for the lack of these conditions, timely rescue measures taken. Therefore, in the production of ductile iron, people have been exploring simple and accurate pre-furnace rapid testing methods.
