Problems solved by technology
With the increase of the cross-sectional size of the billet, the cooling capacity of the cooling system needs to be increased; however, if a support structure is provided to provide complete and continuous support for the steel strip along the direction of the cavity extension, thereby limiting the deformation of the steel strip and ensuring the stability of the steel strip and the crystallization wheel Cooperating, it will inevitably occupy the installation space of the cooling system, the flow of cooling water or the injection path, which will lead to the reduction of cooling capacity, so it is impossible to install the supporting structure of the steel belt

Abstract
The invention relates to a continuous casting equipment of non-ferrous alloy, providing a steel belt wheel-type continuous casting machine for continuous casting of lead belts. A steel belt supporting structure is arranged on the radial outer side of the cavity section corresponding to the crystalizing wheel. The steel belt supporting structure comprises at least one set of supporting bodies, the steel belt being positioned between the supporting body and the crystallizing wheel. One side of the crystallizing wheel corresponding to the steel belt tightly clings to the crystallizing wheel rim on both sides of the crystallizing cavity, while the other side tightly clings to the supporting body; a supporting structure external cooling device and a supporting structure internal cooling device are arranged; the cooling system of the steel belt comprises a steel belt spray cooling device and a contact-type cooling device formed by steel belt supporting structure. By arranging the steel belt supporting structure, the deformation of the steel belt is avoided, and enough cooling capacity is provided, which is applicable to the continuous casting of lead belts of large height and width.
Description
technical field [0001] The invention relates to continuous casting equipment for non-ferrous alloys, in particular to a steel belt wheel continuous casting machine for continuous casting of lead strips. Background technique [0002] The grid is an important part of the lead-acid battery, and its functions include serving as an electronic current collector and immobilizing active materials. 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 its corrosion products 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 structure of the grid to improve the corrosion...
