This paper studies a corrosion-resistant low-carbon steel controlled temperature control rolling process.When the control panel controls the rough rolling device to pre rough roll the phosphorus removed low-carbon steel plate,the rough rolling temperature detector is controlled to detect the actual temperature of the steel plate,and the steel plate temperature is adjusted to the corresponding value according to the comparison between the actual temperature and the preset temperature.When the rough rolling device performs formal rough rolling on the phosphorus removed steel plate,the control panel adjusts the power of each rough rolling roller group in the rough rolling device to the corresponding value according to the thickness of the steel plate,controls the rough rolling temperature detector to detect the actual temperature of the steel plate during the pre rough rolling,and determines whether to adjust the steel plate temperature according to the comparison between the actual temperature of the steel plate and the preset temperature;it can effectively avoid that the steel plate cannot be rolled because the temperature does not meet the standard during rough rolling.
