Cold-rolled sheet manufacturing device

Abstract

The invention relates to the field of cold-rolled sheet manufacturing and pickling equipment, in particular to a cold-rolled sheet manufacturing device which comprises a device body. A plurality of extrusion pushing mechanisms are distributed on the inner side of the device body, and each extrusion pushing mechanism comprises an upper pressing roller and a lower pressing roller which are vertically, correspondingly and rotationally installed on the inner side of the device body. The inner side of the upper pressing roller and the inner side of the lower pressing roller are each provided with aplurality of flow guide channels distributed in an annular array mode, each flow guide channel is in a spiral shape with the screw pitch larger than that of the upper pressing roller, and the two ends of each flow guide channel penetrate through the outer surfaces of the two sides of the upper pressing roller or the lower pressing roller. Each extrusion pushing mechanism further comprises a fixing frame with the two ends fixedly connected to the inner walls of the two sides of the device body, the fixing frame is located in front of the upper pressing roller, and a sliding opening is formed in the upper end face of the fixing frame. The device is beneficial to flowing of the whole pickling solution in the pickling process, flowing of the pickling solution near the upper surface of the plate, cleaning of the surface of the plate and long-term use.

[0002] In the manufacturing process of cold-rolled sheet, it is necessary to pickle the quenched sheet body to remove the oxide layer on the surface to facilitate subsequent processing. Recoil again to complete the pickling process of the cold-rolled sheet, but during the immersion cleaning process, for the lower surface of the cold-rolled sheet, since the liquid is injected from below, and the liquid near the pickling falls under gravity, the cleaning effect It can meet the requirements, but for the upper surface of the cold-rolled plate, the nearby pickling solution flows poorly, and in the process of long-term pickling, the cleaning effect of the surface of the cold-rolled plate is poor, and artificial timing disturbance is required. Secondly, impurity particles will accumulate on the upper surface, so that the board still needs to be scraped and cleaned after being sent out. In addition, in the prior art, the entire cleaning pool is blocked by the water flow due to the large surface area of ​​the board, so that the liquid flows up and down. Poor, also affects the balance of pickling
