摘  要：
According to the structure characetrs to the gray iron castings -with thin -wall and high strength such as engine block and head replaced engine in 80's and the technical requirements of material, and the state situation of China, this paper study system atically the RE-Ca-Ba inoculant and its application conditions and methods, fire elements in molten iron, carbon equivalent, silicon-carbon ration, alloy elements, oxidation, metallurgical and technical factors. A whole set of method about strengthening inoculation has been perfected, which is to take strengthening inoculation as nucleas, higher carbon equivalent as presupposition, the quality of molten iron as base, comprehensive management as guarantee. Also this method has been applied in batch production in many works. As a result, a good technical economic benefit has teen obtained.
