Abstract

PURPOSE: To accelerate soaking through annihilation of skid marks of billets and to assure rolling conditions of high quality in soaking in a billet heating furnace by disposing a movable skid mechanism and a hoisting mechanism for billets in the heating furnace.
CONSTITUTION: A billet heating furnace in a hot rolling line is constituted of movable skids 3 (ascending position) and 5 (descending position) for advancing a heated billet 1, hoisting arms 2 for the billet 1 and stationary skids 4. In the soaking stage of the billet heating furnace, the arms 2 are operated to hoist the billet and to create the state in which the bottom surface of the billet does not contact any of the skids 3 and the skids 4. Skid marks are annihilated by the repetition of conveying and hoisting, whereby the soaking is accelerated, the in-furnace residence time of the steel material is reduced, the treating capacity of the heating furnace is improved and the fuel unit for the billet is reduced.
