Production method of copper plate

The invention discloses a production method of a copper plate, which adopts a continuous furnace to heat a blank, and adopts a hot rolling and cold rolling combined mode to roll the blank, specifically, rough rolling adopts hot rolling, and finish rolling adopts cold rolling. Through the reasonable heating schedule and rolling process, the production of the copper plate with the special specification, the length of which is more than 20000 mm and the width of which is more than 3000 mm, can be realized, and the produced copper plate is good in surface quality, regular in rectangularity and less than or equal to 3 mm/m in unevenness. 本发明公开了一种铜板的生产方法，采用连续炉加热坯料，并采用热轧和冷轧相结合的方式对坯料进行轧制，具体为粗轧采用热轧、精轧采用冷轧。本发明通过合理的加热制度、轧制工艺，可实现长度20000mm以上、宽度3000mm以上特殊规格铜板的生产，且生产的铜板表面质量良好，矩形度正，不平度≤3mm/m。
