摘要

Method for the manufacture of castings with two different metals such as cylinders for steel mills and extrasiderºrgico use, characterized by the use of a mold with a central shell and two portions, one upper and one lower ground, pouring into said mold, until reaching a level slightly higher than said shell, a first molten metal intended to form the central portion or table of the resulting cylinder, also characterized in that said method provides, after the solidification of a pre-established peripheral layer, of this first metal, resulting in contact with the shell mentioned and fused with the spout system, the discharge of the central mass of the solidified metal through the bottom of the mold and the replacement of this first discharged metal with a second type of molten metal poured into the mold. Mold through the same spout casting channel. (Machine-translation by Google Translate, not legally binding)
