Problems solved by technology

At present, the Hazlett process is rarely used in our country, and the production technology is not yet mature. It is difficult to produce complex alloys and wider plates and strips. It is easy to form casting defects such as surface segregation and holes during continuous casting. Therefore, it is urgently needed Develop a production method of continuous casting and rolling decorative strips, break through the bottleneck problem of high-speed production of high-performance decorative strips, and provide technical support for large-scale production of decorative strips

Abstract

The invention discloses a production process of 8011 decorative tape, the composition and mass percentage of the decorative tape are: Fe 0.78-0.82%, Si 0.58-0.62%, Cu 0.035-0.045%, Ti0.020-0.035 %, Mn≤0.01%, Mg≤0.01%, and the balance is Al. The production process includes the following steps: smelting, refining, continuous casting, continuous rolling and cold rolling steps; the present invention adopts continuous casting and rolling technology, continuous casting The machine casting speed can reach up to 6.8m / min, and the continuous casting machine directly enters the MINO three-stand continuous rolling mill through the pinch roller to roll into a billet with a thickness of 2.3mm. Thin, reducing the number of subsequent cold rolling passes and further improving production efficiency.

Description

technical field [0001] The invention relates to an alloy production and preparation method, in particular to a production process of 8011 decorative strip. Background technique [0002] Common decorative strips are directly exported by casting and rolling, and the general export thickness is 6.8mm-7.0mm. After 5-8 passes of rolling in the rolling mill, the finished product thickness is 0.2mm-0.7mm, annealed, and trimmed before finally becoming The finished product has many rolling passes, and there is a one-step cold material process in the middle pass, resulting in a longer production cycle; [0003] Continuous casting and rolling is a rolling process combining continuous casting and continuous rolling. It adopts the Hazlett continuous casting and rolling machine in the United States. The aluminum alloy liquid is injected into the continuous casting machine to cast a 19mm billet, and then directly cast by three consecutive It is rolled by a rolling mill to produce a slab o...
