Abstract

PURPOSE:To perfectly prevent the formation of temper colors by coating the edge parts of a tight coil, charging the coil into a heating furnace and maintaining the same at a prescribed temp. then raising the temp. and applying annealing thereto. CONSTITUTION:Covers 7 made of steel sheets or the like are put on the edge parts of a tight coil 2, and are clamped by steel bands 8 or the like. This is inserted into a batch type heating furnace and is kept for 1-20hr at 250-500 deg.C, whereby the moisture stuck on the tight coil 2 is perfectly removed. Thence, the temp. is raised up to a prescribed temp. and the coil is subjected to annealing. Thereby, the formation of oxidation films on the edge parts of tight coil during annealing is obviated, and the beautiful appearance as a cold-rolled sheet steel is maintained.
