关心墨球铸铁的同志们都很清楚,型内球化处理工艺方法是最近发展起来的一种新技术,它是将球化剂放在铸型浇注系统中的球化反应室中,然后把原铁水浇入铸型,即可获得合乎质量的球铁铸件。由于球化反应是在不与外界空气接触的反应室进行的,所以不会出现烟尘镁光,减少了环境污染,改善了劳动强度;又使球化率、吸收率大大提高,可节省大量的球化剂,且几乎不存在球化衰退和孕育衰退等问题,质量改善,可获得球化良好,没有渗碳体,球园整细,组织致密和机械性能高的铸件。型内球化处理工艺特别适于大量流水作业的机械化生产。型内球化处理工艺方法既然是一种新发展的技术,和任何新生事物一样,也有一定的局限性,例如铁水消耗量增大些,需要有现代化的检测手段,对原铁水的温度,合硫量要求较严 Concerned about the ball of cast iron comrades are very clear that the type of ball treatment process is a recent development of a new technology, which is the nodular cast agent in the mold casting system in the reaction chamber, and then The original molten iron poured into the mold, you can get the quality of ductile iron castings. As the ball reaction is not in contact with the outside air reaction chamber, so there will be no smoke magnesia, reducing environmental pollution and improve labor intensity; and the ball rate, absorption rate is greatly improved, can save a lot of ball There is almost no problems such as the deterioration of pelletizing and the decline of inoculation. With the improvement of quality, it is possible to obtain castings with good spheroidization, no cementite, fine ballpark, dense structure and high mechanical properties. Type of ball treatment process is particularly suitable for a large number of mechanized production of water operations. Since the ball type ball treatment process method is a newly developed technology, as with any new thing, it has some limitations. For example, the consumption of hot metal is increased, which requires modern testing methods. Sulfur requirements more stringent
