Development, Operation and Foundry Application of the Spiral Fluidity Hold for Measuring the Fluidity of Cast Steel

Abstract

A test mold employing a spiral flow channel is described which can be used satisfactorily for measuring the fluidity (castability) of steel in the furnace prior to tapping or in the ladle on the pouring floor. Advantages resulting from the use of this test for measuring the fluidity of the steel made in the three-phase electric arc furnace at the Naval Research Laboratory are described. The results of experimental tests made at the Washington and Norfolk Navy Yards are included. It is possible to follow changes in the castability of steel brought about by deoxidizers and alloying elements or by variations in temperature or in furnace practice. The technique for obtaining such information is described.
