Steel strip coiling temperature control method, device for the same and steel strip processing system

A steel strip coiling temperature control method used in a laminar flow cooling apparatus, the laminar flow cooling apparatus comprising a memory device having stored thereon a first correspondence table and a second correspondence table;

• wherein the first correspondence table comprises speed compensation coefficients, wherein the speed compensation coefficients indicate a relative change rate of a steel strip speed during a steel strip throwing process, and correspond to target thicknesses of a steel strip and target temperature parameters through experimental data, and the second correspondence table comprises speed gain coefficients, wherein the speed gain coefficients indicate an influence rate of the steel strip throwing process on a steel strip speed at different initial steel strip speeds and correspond to the initial steel strip speeds through the experimental data;
• and wherein, the steel strip coiling temperature control method comprises:
• looking up a corresponding speed compensation coefficient from the first correspondence table according to a target thickness of a steel strip and a target temperature parameter, and wherein the target temperature parameter comprises a target final rolling temperature and a coiling temperature;
• looking up a corresponding speed gain coefficient from the second correspondence table according to an initial steel strip speed;
• correcting the steel strip speed based on the speed compensation coefficients and the speed gain coefficients to obtain a corrected steel strip speed;
• wherein, the correcting the steel strip speed based on the speed compensation coefficients and the speed gain coefficients is performed according to a formula:
• Spd_preAdj=Spd_pre*(1−SpdAdj),SpdAdj=SpdComp*SpdGain;
• wherein, Spd_pre indicates the initial steel strip speed;
• SpdComp indicates the speed compensation coefficient;
• SpdGain indicates the speed gain coefficient;
• and Spd_preAdj indicates the corrected steel strip speed;
• and
• increasing or decreasing a cooling efficiency of the laminar flow cooling apparatus according to the corrected steel strip speed.
