Abstract

The invention provides a metal ultra-thin strip four-roller rolling mill with selectable driving modes and a rolling method thereof. The rolling mill comprises a rolling mill mechanical part and a control system, wherein two main driving motors, two main reduction gears and a compound gear box are positioned on the same side of a mill housing; the compound gear box is provided with four output shafts which are connected with an upper support roller and a lower support roller through universal spindles or connected with an upper work roller and a lower work roller through the universal spindles; and the upper driving part and the lower driving part of the compound gear box are independently controlled by the first main driving motor and the second main driving motor respectively and are mutually independent, and the reduction ratio of the upper driving part to the lower driving part is adjustable. The rolling method has a support roller driving mode and a work roller driving mode. When the rolling mill is used for asymmetrical rolling of ultra-thin strips, as asymmetrical rolling can break through the restriction from the minimum rollable thickness of synchronous rolling, the sheet rolling capacity is higher, the on-line adjustment range of the different speed ratio is broad, and the range of rollable raw materials can be effectively expanded.

Description

Technical field [0001] The invention belongs to the technical field of metal rolling, and particularly relates to a metal ultra-thin strip rolling mill with optional transmission mode and a rolling method thereof. Background technique [0002] In recent years, micro-manufacturing technology and micro-forming technology have developed rapidly, and the demand for ultra-thin strips of metals, alloys and metal matrix composites is increasing. These ultra-thin strips are widely used in the microelectronics industry, micro-manufacturing industry, and instrumentation industry. And micro-electromechanical industry, etc. [0003] Ultra-thin strips of metals, alloys and metal-based composite materials are mostly obtained by rolling, and the rolling mills used are mostly multi-roll mills, which have complex structures, high technical barriers and high risks, and high purchase, operation and maintenance costs. Large investments have increased the financial costs of enterprises. Summary of th...
