Research methods of large section ductile iron castings

(1) Modulus method: in 1986, when Lin Rui of Harbin University of science and technology was developing the large section ductile iron end cap, he poured the cube with the same modulus as the end cap casting under the same production conditions. By studying the solidification characteristics of the...
