Title:
METHOD FOR MANUFACTURING DEOXIDIZER FOR STEELMAKING USING WASTE ALUMINUM CANS AND ALUMINUM CHIPS
Document Type and Number:
WIPO Patent Application WO/2015/105394
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a deoxidizer for steelmaking using waste aluminum cans and aluminum chips and, more particularly, to a manufacturing system wherein waste aluminum cans, which have been sorted and recovered from waste cans using magnetic forces and eddy currents, are pulverized; plastic labels, iron components, and various kinds of paper are removed therefrom; the same is molded into an aluminum pulverized product compressed powder (billets for extrusion) using a high-pressure press; the same is subjected to continuous extrusion molding using an aluminum extrusion molding machine; and the same is cut by a predetermined length using a press, thereby manufacturing a product that can be used as an aluminum deoxidizer for steelmaking. The present invention is characterized in that, compared with a technology for manufacturing a deoxidizer by dissolving waste aluminum cans or for manufacturing aluminum ingots, which are generally used conventional schemes, a more stable yield ratio can be secured.
