In order to prevent the steel coil from forming an elliptic collapsing coil when horizontally placed after high-temperature annealing, when the strip steel is subjected to primary annealing, magnesium oxide coating and drying and then is coiled, a thin-wall steel sleeve is sleeved on a coiling machine coiling drum, then the strip steel coil is arranged on the thin-wall sleeve, the steel coil with the thin-wall sleeve in the inner hole is vertically placed in a cover type furnace or an annular furnace for high-temperature annealing, during the high-temperature annealing, the strip steel in the inner layer of the steel coil is bonded with the thin-wall sleeve, and waste materials with the length of more than one hundred meters are arranged in the inner layer after the next procedure of uncoiling. Therefore, the Japanese silicon steel production plant firstly cancels the process of placing the thin-wall sleeve when the strip steel is coiled, uses the electromagnetic crane to hoist the vertical steel coil without the sleeve, and uses the cradle to store the horizontal steel coil.
