The invention provides a hot rolled strip steel sampling method and a sampling line. The method comprises the steps that a to-be-tested steel coil is placed on a fixing saddle; a coil conveying and supporting trolley is utilized for conveying the to-be-tested steel coil to the station of an uncoiling coiling machine along a preset track, the horizontal distance of the coil conveying and supportingtrolley and the height of carrier rollers of the coil conveying and supporting trolley are adjusted till the center line of the steel coil coincides with the center line of the uncoiling coiling machine; an expansion core shaft of the uncoiling coiling machine is inserted in the center of the to-be-tested steel coil, and the expansion degree of the expansion core shaft is adjusted till the steelcoil is fixed; during uncoiling of the uncoiling coiling machine, an uncoiling straightener is utilized for straightening strip steel till the strip steel penetrates through a sampling shear; and a side guider of the uncoiling coiling machine presses a steel strip, and the uncoiling coiling machine reversely rotates and coils the strip steel till the strip steel is coiled into a standard steel coil. By means of the hot rolled strip steel sampling method and the sampling line, the steel coil is subjected to coil conveying, uncoiling, straightening, sampling and coiling, human intervention is not needed in the whole process, and full-automatic running is achieved; and meanwhile, after sampling, the steel strip is coiled into a steel coil in an original shape.
Description
technical field [0001] The invention relates to the technical field of hot-rolled strip steel, in particular to a sampling method and a sampling line for hot-rolled strip steel. Background technique [0002] In the production process of hot-rolled steel strip, it is necessary to test the properties of the strip, and cut a section of steel strip for sampling and testing. However, the existing ground roll uncoiling is mainly used. After the surface inspection and sampling of the uncoiled steel coil, although the ground roll can carry out the coiling operation, the coil shape of the coil after coiling is poor, and the qualified strip steel coil after inspection cannot be processed. Take steel coils with qualified coil shape, especially after the equipment has been put into use for a period of time, due to the wear of the roller surface, the coil shape of the coil is very poor. Even if it is a brand-new equipment, because the ground roll has no guiding means during the coiling ...
