据资料介绍,我国于82年研究成功的一种新型孕育剂──硅钡。孕育效果好,不仅抗衰退能力和墨化能力强,且可减少断面组织的敏感性,提高铸铁的机械性能,改善铸件切削性能。 为此我们用硅钡在现行超硼缸套生产的工艺条件下,进行了一系列试验。研究硅钡孕育对硼缸套金相组织、机械性能及加工性能的影响。 According to the introduction of information, a new type of inoculant successfully researched in our country in the year of 82 is silicon barium. Inoculation effect is good, not only the anti-recession ability and the ink-ming ability, and can reduce the sensitivity of the cross-section of the organization, improve the mechanical properties of cast iron, improve casting cutting performance. To this end, we use barium in the current super boron liner production process conditions, conducted a series of tests. The effect of silicon-on-silicon on the microstructure, mechanical properties and processing properties of boron liner was studied.
