Abstract

The invention discloses a short-flow method for producing 5052H32 aluminum alloy plates, belonging to the technical field of alloy processing. A method for producing 5052H32 aluminum alloy plates in a short process, comprising the following steps: S1, adjusting the formula, melting and casting aluminum slabs: adding 200-300ppm of Zr elements to the alloy formula, and performing aluminum slab melting and casting; S2, preheating: preheating The hot soaking temperature is controlled at 500°C; S3, hot rolling: use 1+4 hot tandem rolling mill to roll, and set the reduction amount, hot rough rolling pass, and hot rough rolling according to the thickness of the finished product during rolling. The thickness and temperature of the middle slab at the exit, the parking and maintenance temperature of the middle slab, the finish rolling exit temperature and the rolling speed; S4, air purging. The invention shortens the process flow and does not require cold rolling; during rolling, the characteristics of the hot rolling process are fully utilized, and the metal microstructure and mechanical property control in the quality requirements of the finished aluminum plate and strip are placed in the hot rolling process for coordinated control.

Description

technical field [0001] The invention relates to the technical field of alloy processing, in particular to a short-flow method for producing 5052H32 aluminum alloy plates. Background technique [0002] In recent years, my country's aluminum processing industry has developed rapidly, and many sets of hot rolling equipment have been introduced from abroad, such as Southwest Aluminum, Nanshan Aluminum, Chalco Ruimin, Henan Zhongfu, etc. These production lines have been put into operation one after another, which has a huge impact on the aluminum processing market at home and abroad. The growth rate of the aluminum plate consumption market is also getting faster and faster, especially the 5-series aluminum alloy plate, and the market demand for the 5052H32 state aluminum plate is strong. [0003] 5052 aluminum alloy belongs to the Al-Mg series heat treatment non-strengthenable aluminum alloy, in which the Mg content is 2.2-2.8%, and the Cr content is 0.15-0.35%. It has medium st...
