Изготовление прессового инструмента из чугуна с шаровидным графитом

Abstract

The technology of production of deformed workpieces made of spheroidal graphite cast iron for pressing tool. The peculiarity of these pieces lies in its high performance which are caused by a compact form of graphite. Pressing tool made of these pieces, suitable for the production of aluminum profiles with high-quality surface. The main elements of the new technology are as follows: modification molten iron, the formation of hollow pieces on the floor mold, heat treatment of castings, special deformation pattern in the manufacture of press matrices, finish machining.
