Abstract

The invention provides a machining process of a thick 5083 aluminum alloy plate for ships. The machining process is characterized by comprising the following steps: sequentially milling, heating, rolling, shearing, drawing to straighten and sawing to fix the size of 5083 aluminum alloy cast ingots, thereby obtaining the 5083 aluminum alloy plate for ships. With the combination of procedures of hot rough rolling, heating, shearing, drawing to straighten and the like of the machining process of the thick aluminum alloy plate, the mechanical property and the anticorrosion property of the thick aluminum alloy plate in an H321 state are improved.

Description

technical field [0001] The invention belongs to the technical field of metal materials, and in particular relates to a processing technology of a marine 5083 aluminum alloy thick plate. Background technique [0002] American Bureau of Shipping (ABS, full name: American Bureau of Shipping) was established in 1862. It is a non-governmental organization mainly dedicated to serving the public interest and customer needs. By developing and verifying the design, construction and operation standards of marine-related facilities, Protect the safety of human life, property and the natural environment. Ships entering the United States need to be certified by ABS. Therefore, in order to expand orders for marine products in order to meet the needs of foreign trade and sales, marine aluminum alloy plates need to meet the specifications of ABS Classification Society and obtain ABS certification. [0003] 5083 alloy has good strength and good machinability among non-heat treatable alloys...
