| description | The invention discloses a cold rolling method of a hot rolling coiler, which comprises the following steps of: starting coiling quick-stop protection equipment after a normal coiling condition is not met, quickly starting shearing when the distance between the tail part of an intermediate billet and a flying shear is detected to be more than or equal to 5m in a finish rolling area with the thickness of strip steel less than 11mm, and completely rolling the strip steel less than 5m; a coiling start quick-stop finishing mill group with the thickness larger than or equal to 11 mm is in linkage start quick-stop roll gap quick opening, all strip steel is poured back to the middle billet push-out line to be processed, a coiling laminar flow pat is lifted to the highest position, three pinch rolls of a coiling machine are lifted to the maximum position, and a valve is closed to the zero position. And the head of the strip steel is straighter and is easy to coil by utilizing the downward pressing and transferring of |
