Steel plate side edge rust removal device and method

Abstract

The invention relates to a steel plate side edge rust removal device and method. The rust removal device includes steel plate side brushing mechanisms oppositely arranged on the left side and the right side of the steel plate, wherein each steel plate side brushing mechanism includes a rack, a placing platform arranged on the rack and moving oppositely to the placing rack, a scale breaking rollerarranged on the placing platform and performing synchronously translational movement with the placing platform, and a guide roller arranged on the placing platform and moving oppositely to the placingplatform. The method includes the following steps: S1: setting the numerical value section of a'-a; S2: adopting a current analog signal acquisition module to acquire current analog signals and sending the current analog signals to a processing module; S3: enabling the processing module to convert the current analog signals into digital signals and sending the digital signals to a control module;S4, judging whether the digital signals are in the threshold value section of a'-a by the control module; S5: if yes, not issuing an order, if no, issuing an order; and S6, issuing an order, and adjusting the positions of the scale breaking rollers. Compared with the prior art, the invention has the following advantages: the positions of the scale breaking rollers can be adjusted according to thepolishing and brushing intensity and the clearances between the scale breaking rollers and the side edges of the steel plate, and the fact that the scale breaking rollers can be used for efficientlypolishing and brushing the side edges of the steel plate in real time, is guaranteed, and the production efficiency and the yield are improved.

Description

technical field [0001] The invention relates to the technical field of derusting steel materials, in particular to a side edge derusting device and method of a steel plate. Background technique [0002] At present, manufacturers basically use pickling to derust steel, but this pickling and derusting method will produce highly polluted sewage, causing serious pollution to the environment, and does not meet the long-term requirements of environmental protection; Physical brushing methods such as scale-breaking rollers, but after repeated brushing, the scale-breaking rollers will wear out, thereby reducing the brushing strength of the steel, and even there is a gap between the steel and the steel, so that the steel cannot be brushed, which seriously affects the product. The pass rate reduces the efficiency and output of steel derusting, and also wastes the power consumption of the entire equipment. [0003] The present invention envisages a method that can adjust the position ...
