Problems solved by technology

[0003] In the automatic production process of steel plate rolling, the problem of offset correction of the steel plate has always been an important reason restricting the automatic production of steel plate rolling. Because the traditional mechanical fixed correction cannot effectively control its strength, it will cause damage to the hot steel plate, and the hydraulic pressure Fixed correction cannot meet the continuous and effective operation in high temperature environment, so a pneumatically controlled automatic production device for steel plate rolling offset correction is proposed

Abstract

The invention discloses a correcting positioning device used in the automatic steel plate rolling process. The device comprises a base, a compression-resistant anti-skid shock pad is arranged at the bottom of the base, conveying supporting columns and rolling supporting columns are fixedly arranged on the base, a conveying supporting beam is arranged on the conveying supporting columns, a plurality of conveying rollers are arranged on the conveying supporting beam, symmetrically-arranged rolling rollers are arranged on the rolling supporting columns, a plurality of adjusting bases are arrangedon the supporting beam, steel plate correcting devices are arranged on the adjusting bases, high-temperature-resistant air cylinders are arranged on the steel plate correcting devices, first air holes, sensors, telescopic rods, adjusting guiding wheels and second air holes are formed in the high-temperature-resistant air cylinders, and rolling roller correcting devices are arranged on the rollingrollers. According to the device, continuous fixing correcting in the steel plate conveying and rolling process is achieved, the restriction problem of the high-temperature environment is solved, thestructure is simple and reasonable, the durability is achieved, the force in the correcting fixing process can be controlled, and jamming in the steel plate correcting fixing process is avoided.

Description

technical field [0001] The invention relates to the field of automatic rolling correction and positioning of steel plates, in particular to a correction and positioning device in the automatic rolling process of steel plates. Background technique [0002] Continuous casting slabs or rough rolling slabs are used as raw materials, heated by a walking heating furnace, descaled by high-pressure water, and then enter the rough rolling mill. After the final rolling, it goes through laminar cooling (computer controlled cooling rate) and coiler coils to become straight hair coils. The head and tail of straight hair curlers are often tongue-shaped and fish-tail-shaped, with poor thickness and width precision, and the edges often have defects such as wavy, hemmed, and tower-shaped. [0003] In the automatic production process of steel plate rolling, the problem of offset correction of the steel plate has always been an important reason restricting the automatic production of steel pl...
