锶(Sr)系孕育剂,自1963年英国获得“专利”以来,由于其具有特殊的功效而在欧美一些国家得到广泛地应用。尤其是在生产薄壁、高强度铸件的发动机方面,使用得更为普遍。 目前,我国在生产发动机的行业中,缸体、缸盖等铸件,还存在着严重的渗漏现象。针对这一问题,我院材料强度研究室对锶系孕育剂的研制,经过近一年的努力,已取得较好的成效。 Strontium (Sr) -based inoculant has been widely used in some countries in Europe and America since its patent was obtained in 1963 in the UK. Especially in the production of thin-walled, high-strength castings of the engine, the use of the more common. At present, China’s production of engine industry, cylinder block, cylinder head and other castings, there are still serious leakage phenomenon. In response to this problem, the research laboratory of material strength of our hospital on strontium series inoculant, after nearly a year of efforts, has achieved good results.
