Thin belt material single-rack continuous mill and implementation method

Abstract

The invention discloses a thin belt material single-rack continuous mill and an implementation method. The thin belt material single-rack continuous mill is provided with a plurality of work rollers which have the same or different diameters. The work rollers include drive rollers and driven rollers. Multi-pass asynchronous rolling or asynchronous and synchronous rolling is implemented by controlling the linear speeds of the drive rollers. Along with the increase of the rolling pass number, the linear speeds of the rollers are sequentially increased in the rolling direction, and the last pass can adopt either asynchronous rolling or synchronous rolling. When synchronous rolling is adopted, the roller diameters of the last two rollers are the same, and the linear speeds of the rollers are the same. The thin belt material single-rack continuous mill and the implementation method have the beneficial effects that multi-pass continuous rolling is realized in a single rack, larger rolling reduction can be realized in one rolling length, the rolling production efficiency of an ultra-thin belt is improved, equipment investment and occupied space are reduced, and meanwhile the production, operation and maintenance expenses are reduced accordingly; and the transverse rigidity of the rollers can be improved, the transverse thickness deviation of a rolled piece is small, and the plate shape quality of products can be improved.

Description

technical field [0001] The invention belongs to the technical field of plate and strip rolling, and is particularly suitable for a single-stand continuous rolling mill and a rolling method for efficiently producing thin strips and ultra-thin strips. Background technique [0002] With the rise of new manufacturing industries such as micro-manufacturing and micro-electromechanical, the market has an urgent demand for ultra-thin strips. At present, most of the ultra-thin strips made of metals, alloys, and metal matrix composites on the market are obtained by rolling, and the production equipment mostly uses multi-roll rolling mills. The traditional multi-roll mill represented by the Sendzimir 20-roll mill has a large investment, a large floor area, a complex structure, and high production, operation, and maintenance costs. At the same time, limited by the minimum rollable thickness of synchronous rolling, the thinning capacity of multi-roll mills is low, and many passes of rep...

Problems solved by technology

The traditional multi-roll mill represented by the Sendzimir 20-roll mill has a large investment, a large floor area, a complex structure, and high production, operation, and maintenance costs.

At the same time, limited by the minimum rollable thickness of synchronous rolling, the thinning capacity of multi-roll mills is low, and many passes of repeated rolling are usually required to obtain ultra-thin strips, resulting in low production efficiency and high cost of ultra-thin strips

There have been attempts abroad on multi-stand Sendzimir continuous rolling mills, but they have not been popularized and applied because of the high cost and technical complexity.
