Abstract:
A method and apparatus for producing modified grey iron, and particularly nodular cast iron, is disclosed. The apparatus comprises refractory elements including an inclined flow course for continuous reception of molten grey iron, a V-shaped inclined receptacle interposed in said course into which a predetermined supply of modifying agent, such as magnesium, is injected to react with said iron, and means for controlling the egress of iron from the receptacle in order to sequentially stage the build-up and dissipation of a pool of iron in said receptacle facilitating chemical reactions and thorough mixing for attaining and improving the homogeneity of the modified iron elements. The product and composition uniquely is characterized by about 3. 5 carbon, by weight, 2. 5% silicon, 0. 2-0.
