Title:

IMPROVEMENTS IN METALLURGICAL CONVERSION

Document Type and Number:

WIPO Patent Application WO/1995/023660

Kind Code:

A1

Abstract:

The proposed improvements in metallurgical conversion according to the invention involve the production of a semi-finished product (a mixed blank) in the form of an ingot through casting in a mould of a casting facility from a solid filler, preferably an oxidizer, and liquid pig iron which is subsequently cooled. Action is taken during the process to prevent the solid filler in the liquid pig iron from flaring. This is done both by the application of a mechanical force which can be created by, for example, a cantilever (8) with a hollow roller (9) which acts on the mould (2), and a weighting unit (10), and by the selection of suitable relative dimensions of the solid filler pieces and of the pouring rate. The optimal conditions are disclosed for the use of the semi-finished article in metallurgical conversions in oxygen converters and electric arc furnaces.
