本文通过正交试验和方差分析以及系列对比试验得出,稳定剂FeCr、FeV都有增加白口和过冷石墨减少麻口的能力;各种孕育剂都有减少白口、麻口和过冷石墨的能力,但它们的能力大小各有不同、而且对各区的影响也不成比例。1~#Re减少白口的能力最强、BaSi和CaSi次之,75SiFe最弱.但对减少麻口和过冷石墨的能力来说,BaSi、CaSi和75SiFe三者相近,1~#Re最弱。因此,采用1~#Re与BaSi、CaSi或75SiFe等的复合孕育剂,可获得同时减少白口、麻口和过冷石墨良好的孕育效果。复合孕育剂经在X4115缸工盖生产中验证,收到了预期的效果。
In this paper, orthogonal test and analysis of variance as well as a series of comparative tests concluded that the stabilizer FeCr, FeV have white and overcooled graphite to reduce the capacity of Ma mouth; all kinds of inoculants have to reduce the white mouth, Ma mouth and cold Graphite, but their ability to vary in size, and the impact on the districts is not proportional. 1 ~ # Re has the strongest ability to reduce the white mouth, followed by BaSi and CaSi and 75SiFe the weakest, but BaSi, CaSi and 75SiFe are similar to each other, weak. Therefore, the use of 1 ~ # Re and BaSi, CaSi or 75SiFe composite inoculant can be obtained at the same time reduce the white mouth, Ma mouth and supercooled graphite good inoculation effect. The compound inoculant was validated in the X4115 cylinder cover production and received the expected result.
