一种舰船船体用铝合金大规格扁铸锭的制造方法
摘要：
一种舰船船体用铝合金大规格扁铸锭的制造方法，本发明涉及一种铝合金大规格扁铸锭的制造方法。本发明的目的是为了解决现有方法制造的舰船船体用铝合金大规格扁铸锭，力学强度及耐蚀性差和寿命低的问题。本发明的舰船船体用铝合金大规格扁铸锭由按重量百分比为0.7％～1.1％Mn、5.5％～6.5％Mg、0.03％～0.15％Zr、0.10％～0.30％Er和余量的Al作为熔炼原料而制成。本发明的舰船船体用铝合金大规格扁铸锭按以下步骤进行：一、称取一定量的含Mn、Mg、Zr、Er和Al五种元素的五种物质，二、制备铝合金熔体，三、半连续铸造得到舰船船体用铝合金大规格扁铸锭；本发明的铝合金大规格扁铸锭用于舰船船体上。
摘要（英）：

The invention provides a method for manufacturing an aluminum alloy large-sized flat ingot for a ship body, relates to a manufacturing method for the aluminum alloy large-sized flat ingot, and aims to solve the problem that an aluminum alloy large-sized flat ingot which is prepared according to a conventional preparation method and used for the ship body is poor in mechanical strength and corrosion resistance, and short in service life. The aluminum alloy large-sized flat ingot provided by the invention is prepared from the following raw materials for smelting in percentage by weight: 0.7-1.1% of Mn, 5.5-6.5% of Mg, 0.03-0.15% of Zr, 0.10-0.30% of Er and the balance of Al. The preparation method provided by the invention comprises the following steps: 1, weighing certain amount of such five elements of Mn, Mg, Zr, Er and Al; 2, preparing an aluminum alloy melt; and 3, carrying out semi-continuous casting to obtain the aluminum alloy large-sized flat ingot. The aluminum alloy large-sized flat ingot is applicable to the ship body.
