Abstract

The invention discloses a device and method for producing metal composite sheet strips through corrugated-flat continuous rolling. The method is characterized in that a base material steel coil and a composite material steel coil are uncoiled through uncoilers, cleaned through a cleaning device to remove oxide layers and then rolled into a composite sheet strip through a corrugated-flat cold continuous rolling unit, and the composite sheet strip is annealed through a continuous annealing device and then coiled to obtain a composite sheet coil. The corrugated-flat cold continuous rolling unit is composed of a double-roller corrugated rolling mill and a four-roller flat rolling unit. When double-layer sheet strips need to be produced, a roller system of the double-roller corrugated rolling mill comprises a corrugated roller and a flat roller, and the corrugated roller always makes contact with a large-deformation-resistance metal layer; when three-layer sheets need to be produced, the roller system of the double-roller corrugated rolling mill comprises two corrugated rollers, and the two corrugated rollers make contact with a large-deformation-resistance composite layer. In corrugation section dimensions, the corrugation depth is s, and the corrugation width is t; the thickness of the large-deformation-resistance metal layer is h0, i.e., s / h0=(0.1-10), and t=(10-20)s. By using the corrugated-flat cold continuous rolling unit, the problem that composite sheet strips buckle, crack and have large residual stress due to the difference of deformation resistances of dissimilar metals is solved, and the composite ratio is high.

Description

technical field [0001] The invention belongs to the technical field of metal composite plate and strip material processing, and specifically relates to a production device and method for wave flat continuous rolling metal composite thin plate and strip. Background technique [0002] With the rapid development of science and technology, the birth of a number of high-tech industries has put forward higher requirements for the performance of materials. At the same time, in order to reduce costs, save resources, reduce energy consumption, and improve product performance, scholars at home and abroad are committed to Research and develop new bi-metal or multi-metal composite plates and new rolling processes. Metal composite material technology can give full play to the respective advantages of component materials, realize the optimal allocation of component material resources, save precious metal materials, and achieve performance requirements that cannot be met by a single metal....
