METHOD FOR MAKING CONTINUOUS DEFORMED HOLLOW BILLETS FROM DISINTEGRATED METAL AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 2003 - IPC

Abstract RU 2198056 C2

FIELD: metallurgy, namely manufacture of continuous deformed hollow billets from disintegrated metal and melt metal. SUBSTANCE: method comprises steps of simultaneously pouring into center of mold disintegrated metal similar to cast metal in quantity 40-60 mas.% and reducing metal mixture on walls with inclined upper parts and on central core. Apparatus for performing the method includes vessel for disintegrated metal having batching device in the form of auger and arranged in mean zone of casting vessel. Width "A" of vessel with disintegrated metal and spacing between two windows on platform ≪A1≫ are related by expression A/A1 = 1,3-1,5.. Cone shaped hood is mounted over central core. EFFECT: enhanced quality of surface and inner structure of billets, improved operational efficiency of apparatus. 2 cl, 2 dwg
