This invention discloses a method and apparatus for sorting and grading cold-rolled strip steel based on a gray-level co-occurrence matrix and a decision tree, relating to the fields of metallurgical machinery and automation technology. It includes: acquiring image data and text data of the surface of the cold-rolled strip steel to be graded; inputting the image data and text data into a pre-constructed surface quality sorting and grading model for cold-rolled strip steel; and obtaining the surface quality sorting and grading result of the cold-rolled strip steel based on the image data, text data, and the surface quality sorting and grading model. This invention enables better intelligent judgment of the surface quality of cold-rolled strip steel, improves the accuracy of surface quality judgment, and makes the judgment system results more relevant to quality inspectors.

The utility model provides a kind of self-sliding adjustable control rolling machine, comprising: rolling equipment;Two resting tables are respectively opened in the surface of rolling equipment two sides, and the surface of one of resting tables is fixedly installed with sliding device in two sides, sliding device includes fixed block, guide pillar and elastic piece, two fixed blocks are respectively fixedly installed in the upper and lower sides of the surface of resting table, the two ends of guide pillar are respectively fixedly connected in the two sides of two fixed blocks, and elastic piece is sleeved in the one side of the outer surface of guide pillar.The utility model provides a kind of self-sliding adjustable control rolling machine, by setting saddle block into slidable saddle, the setting of elastic piece makes that when saddle drives steel roll to stand up, saddle block and bearing block are moved downward together with steel roll gravity, can effectively improve and avoid rolling bag operation material and saddle contact surface skid, cause the case of outer package quality problem, further reduce the quality objection caused by appearance quality, improve the practicability of the device.

The invention discloses an evaluation method, system, medium and equipment for evaluating the quality management system of each production department of an iron and steel enterprise, and the method comprises the steps: referring to the standard of the quality management system for the quality management system of each production department of the iron and steel enterprise according to a customer guiding process, a supporting process and a management process; dividing a to-be-evaluated production department quality management system to obtain a quality target under each process; according to the quality target under each process, respectively designing a corresponding quantitative evaluation index and a corresponding qualitative evaluation index, designing a weight, a scoring standard and a scoring mode for each evaluation index, and carrying out step-by-step weighting on the weights according to the process and the evaluation indexes; and based on the weight, the scoring standard and the scoring mode designed by each evaluation index, evaluating step by step according to the evaluation index and the process to obtain an effectiveness score about the to-be-evaluated production department quality management system.

The invention belongs to the technical field of hot rolling detection, and provides a nickel plate convexity detection method based on a G1886 multifunctional instrument, which comprises the following steps: manufacturing nickel plate sample wafers with different specifications and thicknesses, analyzing chemical components of the nickel plate sample wafers with different specifications and thicknesses, inputting the specifications, thicknesses and chemical components of the nickel plate sample wafers into measurement real-time parameters of the multifunctional instrument, and completing automatic calibration. The method comprises the following steps: placing nickel plate sample wafers in a multifunctional instrument measurement area, determining an accurate nickel plate thickness compensation coefficient, and establishing a thickness compensation curve corresponding to the nickel plate sample wafers with different thicknesses; during measurement, the compensation amount is calculated according to the compensation curve, and finally the accurate thickness value of the nickel plate is calculated. According to the method, the problem that the G1886 multifunctional instrument cannot detect the thickness of the nickel plate is solved, the reject ratio of the nickel plate type is reduced, the quality of the nickel plate type is improved, stable and efficient nickel plate type measurement is achieved, and good economic benefits are obtained.

According to the battery shell quality judgment method based on the battery steel before rolling release, internal inclusion defect detection is established for each rolled strip steel before release, defect data are formed, and according to the defect data, whether the strip steel is blocked or not is judged in combination with simulation of user basketing and sampling inspection. According to the method for judging the quality of the battery shell before rolling release of the battery steel, a quantitative standard is established for blocking of the battery steel, and meanwhile, whether the quality of the battery shell meets the standard of a user side or not can be judged before release of the strip steel.

The invention relates to the technical field of ferrous metallurgy, in particular to a method for preventing a middle plate from bending crack in machining, which comprises the following steps of: a, optimizing hot rolling burr scaling; b, the shearing temperature of the steel plate is controlled, specifically, an air mist cooling module is installed above the steel plate to be cooled, and a plurality of cooling sprayers are adjusted; c, placing the steel plate: placing the steel plate to be treated in the shear blade device; d, circle shear adjustment: adjusting the horizontal gap of the circle shear and the overlap amount of upper and lower shear blades. According to the method, by optimizing the hot rolling burr size, controlling the shearing temperature, reasonably adjusting the horizontal gap of the circle shear and adjusting the overlapping amount, the shearing quality is improved, the quality objection is reduced, and huge economic benefits are guaranteed.
