Embodiment Construction

[0019] The present invention will be further described below in combination with specific embodiments.

[0020] The invention provides a method for manufacturing an aluminum alloy plate for a freight train carriage, comprising the following steps:

[0021] A. Melting, refining and degassing: Feed and smelt according to the various elemental components of the 5083 aluminum alloy ingot production. The temperature is controlled between 735-745°C, and then transferred to the holding furnace for refining. The refining temperature is 720-730°C. The refining gas is a mixture of nitrogen and chlorine. The refining time is 40 minutes. The addition amount is 0.2%, and after online degassing with chlorine-argon mixed gas, an aluminum material with Na%≤0.0005% and hydrogen content≤0.25ml / 100gAl can be obtained;

[0022] Preferably, the melt temperature is 710°C, 720°C or 730°C. If the melt temperature is too low, it is not conducive to the dissolution of alloy elements and the discharge ...

Description

【Technical field】 [0001] The invention relates to a method for manufacturing an aluminum alloy plate, in particular to a method for manufacturing an aluminum alloy plate for freight train carriages. 【Background technique】 [0002] Lightweight has become the development trend of rail transportation. Aluminum freight cars are one of the effective ways to lighten freight cars. The aluminum alloy plates used for freight train carriages have the following disadvantages in the prior art: the rough process easily leads to surface scratches. Severe scratches and aluminum sticking, poor quality of hot-rolled billets, product performance—especially unstable anti-corrosion performance, poor uniformity, product performance needs to be improved. 【Content of invention】 [0003] The purpose of the present invention is to provide a method for manufacturing aluminum alloy plates for freight train carriages with rigorous technology, good product performance and stable product performance, s...
