根据高强度孕育铸铁(HT35—61)对孕育剂性能的要求,在含Ba的钙系孕育剂中和在含Ba的稀土系孕育剂中进行了选择性试验研究。试验用ЛΓП3—60型电炉熔化铁水,每次处理8kg,孕育剂加入量皆为0.5%,结果表明;含Ca10%左右,含Ba6—10%的Ca—Ba孕育剂具有生核能力强、白口倾向小、抗衰退性能好的特点,经生产验证和批量生产表明:Ca—Ba孕育剂是生产HT35—61的有效孕育剂。 According to the requirement of inoculant for high strength cast iron (HT35-61), selective test was carried out in calcium-containing inoculant containing Ba and rare earth inoculant containing Ba. Experiment with ЛΓП3-60-type electric furnace molten iron, each treatment 8kg, inoculant were added in an amount of 0.5%, the results show that; containing about Ca10%, containing Ba6-10% Ca-Ba inoculant with a strong nuclear ability, white Mouth tendency is small, anti-recession performance is good, the production verification and mass production shows: Ca-Ba inoculant is HT35-61 production of an effective inoculant.
