Abstract

The invention discloses a method for producing a 5052H32 aluminum alloy plate in a short process, and belongs to the technical field of alloy machining. The method for producing the 5052H32 aluminum alloy plate in the short process comprises the following steps that S1, a formula is adjusted, and an aluminum slab ingot is cast, specifically, 200-300 ppm of Zr element is added to the alloy formula, and the aluminum slab ingot is cast; S2, preheating is performed, specifically, the soaking temperature of preheating is controlled to be 500 DEG C; S3, hot rolling is performed, specifically, rolling is performed by the aid of a 1+4 hot continuous rolling mill, and the rolling reduction, the rolling pass of hot rough rolling, the thickness and temperature of an intermediate plate blank at a hot rough rolling outlet, the parking holding temperature of the intermediate plate blank, and the temperature and rolling speed of a finish rolling outlet are set according to the thickness matching of a finished product during rolling; and S4, air purging is carried out. The technological process is shortened, and cold rolling is not needed; and during rolling, the characteristics of the hot rolling technology are fully exerted, and the metal microstructure and mechanical property control in the quality requirement of the aluminum plate strip finished product plate is carried out in the hot rolling procedure for cooperative 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...
