The application discloses a method for correcting the first-pass roll gap zero point of a heavy plate finishing mill, which comprises the following steps: S1, variable selection, selecting variables related to the correction of the first-pass roll gap zero point of the heavy plate finishing mill from historical data; S2, performing data cleaning and feature extraction on the variables selected in the step S1; S3, using a random configuration network algorithm to establish a model for correcting the first-pass roll gap zero point of the heavy plate finishing mill; and S4, using the model for correcting the first-pass roll gap zero point of the heavy plate finishing mill established in the step S3 to set the first-pass roll gap zero point correction value. The application is based on a large number of effective historical data related to the setting of the roll gap zero point correction value, and uses the random configuration network algorithm to correct the first-pass roll gap zero point of the heavy plate finishing mill after the gauge change in the finishing process of the heavy plate finishing mill, so that the thickness accuracy of the slab is improved.

This invention discloses a prefabricated wall panel and its manufacturing process, relating to the field of prefabricated building technology. The wall panel includes a concrete slab and a steel mesh embedded within the concrete slab. The steel mesh is composed of multiple horizontally and vertically interwoven steel wires, with both ends extending beyond the concrete slab to form exposed connection ends. During manufacturing, the steel mesh is precisely fixed in a predetermined position within a mold using a mechanical locking method. Concrete is then poured, and after curing and demolding, the wall panel with exposed steel wires at both ends is obtained. This invention facilitates on-site assembly and welding by extending the steel wires at both ends of the steel mesh beyond the panel. Simultaneously, the mechanical locking method solves the problem of easy displacement of the steel mesh during pouring, significantly improving the production efficiency and positioning accuracy of the wall panel, making it suitable for industrial mass production.
