Method of operating a reheating furnace in hot rolling line

摘要

A method of operating a reheating furnace in a hot rolling line and a heating furnace therefor in which the reheating furnace is positioned between a continuous casting apparatus and a rolling apparatus rolling workpieces at a higher speed than they are cast by the casting process, the furnace serving as a heating and buffer zone. The heating furnace is longitudinally divided into two heating sections which are changed over so as to receive workpieces for heating and the workpieces are charged into one of the two sections after the other of the two sections has been filled up. The furnace is operated to collectively forward the workpieces heated up to predetermined rolling temperatures to the rolling apparatus for efficient rolling.
