The invention relates to a continuous-rolling mill train for metal plate belts, and provides a continuous-rolling production line of a continuous-casting and continuous-rolling lead belt for preparing a slab lattice. The continuous-rolling production line comprises a first rolling mill, a second rolling mill, forced cooling equipment between the first rolling mill and the second rolling mill, androller ways for connecting all the equipment, wherein a roll of each gate of the second rolling mill is independently driven by a speed regulating motor respectively, and a coiling mechanism is also driven by the speed regulating motor; and the forced cooling equipment comprises at least one cooling trough, the upper parts of two sides of the cooling trough are provided with an opening respectively, an upper limiting roll and a lower limiting roll are arranged in the openings respectively, a pressing down structure is arranged in the cooling trough, and a lead belt conveying surface formed bythe pressing down structure and the lower limiting rolls at two sides has an arch shape with an upward opening. The first rolling mill, the forced cooling equipment and the second rolling mill are used for performing continuous rolling with multiple temperature sections on the lead belt, so that the performance of the produced lead belt is superior to that of the traditional continuous-casting and continuous-rolling lead belt, and the continuous-rolling production line is suitable for producing lead belts for electrode slab lattices of lead acid storage batteries.
Description
technical field [0001] The invention relates to a continuous rolling unit for metal strips, in particular to a continuous rolling production line for preparing continuous casting and rolling lead strips for grids. Background technique [0002] The electrode grid acts as an electronic current collector and at the same time plays the role of immobilizing active substances, and is an important part of the lead-acid battery. During the use of lead-acid batteries, porous active substances will permeate sulfuric acid, causing corrosion of the grid, affecting the cycle life of the grid, and further affecting the durability of the battery; at the same time, the transfer of electrons requires the grid to have Good electrical conductivity requires that the corrosion products of the grid have low impedance during use, especially the positive grid. There is a close relationship between the corrosion resistance of the grid and the crystal structure, so in order to improve the crystal st...
