自1980年起,在哈工大和常州柴油机厂多次进行珠光体型球化剂的试验研究.六年来的试验和生产结果表明,浇注的大量S195球铁曲轴珠光体量稳定在85%以上,石墨球有所改善,渗碳体降至最低;该曲轴除保持原有的高延伸率外,抗拉强度和冲击韧性有明显提高,综合机械性能良好,达到了予期的试验目的,满足了生产要求. The pearlite nodularizer has been tested many times at HIT and Changzhou Diesel Engine Factory since 1980. The results of the tests and production over the past six years show that the amount of pearlite of a large number of cast S195 ductile iron cams stabilized at 85% And the cementite is reduced to a minimum; besides maintaining the original high elongation rate, the crankshaft has obviously improved tensile strength and impact toughness, comprehensive mechanical properties are good, and the purpose of the trial has been reached and meets the production requirements.
