Temperature control and rolling process for corrosion-resistant low-carbon steel

Abstract

The invention relates to a temperature control and rolling control process for corrosion-resistant low-carbon steel. A control panel controls a rough rolling device to carry out pre-rough rolling on a dephosphorized low-carbon steel plate; the control panel controls the rough rolling temperature detector to detect the actual temperature of the low-carbon steel plate and adjusts the temperature of the low-carbon steel plate to a corresponding value according to comparison between the actual temperature of the low-carbon steel plate and the preset temperature; when the rough rolling device performs formal rough rolling on the dephosphorized low-carbon steel plate, the control panel adjusts the power of each rough rolling roller group in the rough rolling device to a corresponding value according to the thickness of the low-carbon steel plate; during pre-rough rolling, the control panel controls the rough rolling temperature detector to detect the actual temperature of the low-carbon steel plate, and whether the temperature of the low-carbon steel plate is adjusted or not is judged by comparing the actual temperature of the low-carbon steel plate with the preset temperature; and the situation that the low-carbon steel plate cannot be rolled due to the fact that the temperature does not meet the standard in the rough rolling process can be effectively avoided, and the low-carbon steel preparation efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of steel rolling, in particular to a temperature-controlled rolling process for corrosion-resistant low-carbon steel. Background technique [0002] Rolling is a metal processing process, which refers to a pressure processing method in which a metal blank passes through the gap between a pair of rotating rolls, and the cross-section of the material is reduced and the length is increased due to the compression of the rolls. [0003] At present, the more commonly used rolling technologies in the world include continuous rolling technology and controlled rolling technology. Among them, the continuous rolling process enables the low-carbon steel plate to be continuously and uninterrupted from the previous process to the next process, and rolled to the target at one time. Thickness, therefore, has the characteristics of high efficiency, low energy consumption, and convenient control; but the continuous rolling pro...
