The invention provides a shake type material receiving and discharging rolling mill and a using method thereof. The shake type material receiving and discharging rolling mill comprises a feeding roller, a rolling machine table and a material receiving roller which are sequentially arranged, wherein the rolling machine table comprises working rollers which are vertically opposite and further comprises a control pivot for controlling a separation distance of the working rollers, a first thickness measurement device and a second thickness measurement device are arranged in front and back of the working roller and are electrically connected with the input end of the pivot, the feeding roller is installed on a first shake device, the first shake device comprises a first longitudinal-transverse rail base and a first shake robot movably arranged above the first longitudinal-transverse rail base, and the first shake robot is electrically connected with the output end of the control pivot. The shake type material receiving and discharging rolling mill adjusts a belt material receiving and discharging state through the shake device and enables the belt material to be fed into the position between the working rollers in a lateral stress balance state. Therefore, bad deformation of products formed through rolling due to residual stress can be avoided, and the accuracy of final products is improved.
Description
Technical field [0001] The invention relates to the technical field of rolling mills, in particular to a rocking type retracting and unwinding rolling mill and a method of use thereof. Background technique [0002] Flexible rolling refers to the application of on-line optimization control technology of microstructure and performance to the rolling process, using billets of the same composition to produce products with different properties, simplifying the operation and management of steelmaking and continuous casting, and achieving flexible control of steel properties Mass customization of rolling production. Its characteristic is that it can significantly reduce the cost of the production process, simplify the operation and management of steelmaking and continuous casting, which is the development trend of future steel production technology. [0003] The flexible rolling process can be used to produce metal strips whose thickness changes periodically. The original rolled strip m...
