Description

Technical Field

[0001] The utility model relates to the technical field of steel materials, in particular to a rolling mill for steel production. Background Art

[0002] A rolling mill is a device that performs the metal rolling process, generally referring to the equipment that completes the entire process of rolling production. Rolling mills can be categorized by the number of rollers, including two-roll, four-roll, six-roll, eight-roll, twelve-roll, and eighteen-roll types. Roller arrangement can further categorize them into "L," "T," "F," "Z," and "S" types. Conventional rolling mills primarily consist of rollers, a stand, a roll gap adjustment device, a roll temperature control device, a transmission, a lubrication system, a control system, and a roll removal device. Precision rolling mills, in addition to the essential components and devices of conventional rolling mills, also incorporate devices to ensure rolling accuracy. Rolling is a metalworking process in which a metal billet is passed through the gap between a pair of rotating rollers, where compression by the rollers reduces the material's cross-section and increases its length.

[0003] According to Chinese Patent Publication No. CN116441371A, the technical solution disclosed in the patent document is as follows: The present invention discloses a rolling mill for steel production, specifically comprising: a fixed double plate, the fixed double plate having a stable base, the fixed double plate having an angle plate fixedly connected to the outside, the top of the angle plate fixedly connected to the top plate, the bottom of the fixed double plate fixedly connected to a fixed cylinder, the inside of the fixed cylinder fixedly connected to an auxiliary mechanism; a fixed mechanism for transporting and receiving steel plates and preheating the steel plates, the fixed mechanism including a back plate, the outside of the back plate fixedly connected to a pushing assembly, the inside of the fixed double plate slidingly connected to a lifting frame, the bottom of the lifting frame fixedly connected to an electric telescopic column; a rolling mechanism for rolling the steel plates into an I-shape, the rolling mechanism including a fixed box, the present invention relates to the field of rolling mill technology. This precision rolling mill for rolling I-shaped steel achieves the purpose of improving the efficiency of equipment use.

[0004] However: When the device is in the hot rolling process, simply put, a piece of steel billet is heated and then rolled several times, and then trimmed and corrected into a steel plate. This is called hot rolling. A lot of iron chips will be generated during trimming. If the iron chips are not cleaned, they will enter the rolling mill. If there are too many iron chips, once they enter the screw rod and guide rail, they will damage the rolling mill and affect the service life of the rolling mill. Utility Model Content
