PROCEDURE FOR HEATING BLANKS AT SECTION AND WIRE MILLS Russian patent published in 2011 - IPC C21D1/34 B21B1/18 C21D8/06

Abstract RU 2430977 C1

FIELD: metallurgy.

SUBSTANCE: blank is preliminary heated in heating furnaces to temperature of 800-850°C and cleaned from scale at given temperature. Further, it is heated to temperature of rolling in a heating installation by conductive and/or inductive procedure. Also, the said installation, roller-bed transporting blank to it and roller-bed transporting blank to a roughing train are covered with heat insulated jacket filled with protective gas.

EFFECT: reduced exhaust of harmful substances, reduced scale formation, increased quality of section iron, facilitation of uniform blank heating by length and cross section.
