Machine Casting of Ferrous Alloys

Abstract

This report covers work carried out in the past six months on the following subjects. (1) The various casting systems built during the first six months of the contract period were modified and improved. A new technique was developed for the production of Rheocast ingots of low temperature alloys semi- continuously. A 400 ton Lester cold chamber horizontal die casting machine was acquired and is being installed for future experiments. (2) The important variables in a continuous slurry producer, a Rheocasting apparatus, were identified and the relationship between these variables and the structure of the primary solid particles in slurries of Sn-15%Pb alloy and X-40 cobalt base superalloy was determined. These structures were compared to conventional dendritic structures solidified under identical average cooling rates. (3) The relationship between gating systems, process variables, and mold filling characteristics in a casting machine were established through transparent mold filling studies using dimensionless numbers.
