Rapid Cycle Casting of Steel

Abstract

A rapid-cycle casting process for steel vis diffusion solidification (SD) has been developed. Solidification takes place by carbon redistribution between iron-saturated high-carbon liquid iron and low carbon pre-existing solid iron in a refractory mold. Since no heat need be rejected to the surroundings during this process, the solidification time is shorter and the economic scaling law is less dependent on the size of the casting than in conventional casting processes. The metallurgical and processing aspects of SD casting were addressed and the necessary parameters have been developed to design a rapid cycle casting machine. These process parameters in addition to the metallurgical quality variables have been included in an economic feasibility analysis of the SD process.
