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.
