The continuous casting and rolling method for preparing 5183 aluminum alloy wire rod has the advantages of high production efficiency, moderate cost, stable wire rod quality, hydrogen content less than or equal to 0.12 ml / 100 g, and excellent mechanical properties.

Description

technical field [0001] The invention relates to a continuous casting and rolling process for wire rods for aluminum alloy welding wires, in particular to a continuous casting and rolling method for preparing wire rods for 5183 aluminum alloy welding wires. Background technique [0002] ER5183 is usually used as AlMg4.5Mn alloy filler metal, which is a non-heat-treatable aluminum alloy. The composition is: 4.3%-5.0% magnesium, 0.5-1.0% manganese and appropriate chromium and titanium, which can be used for MIG or TIG welding of bobbins or longitudinal incisions. As a general-purpose welding consumable with a wide range of uses, this This alloy is generally used in the welding process of ships, drilling equipment, trains, automobiles, storage tanks and pressure vessels. The applicable base metals include 5083, 5086, 5456, 5052, 5652 and 5056. [0003] Welding wire is an important factor affecting the weld metal composition, structure, liquid-solidus temperature, thermal cracki...
