Description

Technical Field

[0002] At present, researchers in related fields have developed a variety of auxiliary feeding devices for the production and feeding of heavier cold-rolled steel coils (referring to steel coils processed by cold rolling process). For example, the authorized patent with announcement number CN206199913U and subject name of a feeding trolley for producing cold-rolled steel coils proposes that "the feeding trolley for producing cold-rolled steel coils is provided with a first infrared irradiator and a second infrared irradiator. Since the supporting columns and the supporting cross bars are retractable devices, the first infrared irradiator is placed below the center of the steel coil by stretching the supporting columns and the supporting cross bars, and then the second infrared irradiator is placed above the center of the steel coil by stretching the supporting columns and the supporting cross bars. When the hydraulic lifting cylinder is used to control the rise of the raw steel coil, the center position of the steel coil can be located by the first infrared irradiator and the second infrared irradiator. When the core shaft of the uncoiler is between the irradiation light of the first infrared irradiator and the second infrared irradiator, the feeding work can be carried out."
