Problems solved by technology

At present, the domestic continuous casting and rolling method to produce aluminum alloy welding consumable billets is immature in terms of production process, technology and equipment, and no qualified products have appeared so far, and this method has large investment, high energy consumption and high production cost.
Although the second preparation method has less investment in equipment and a relatively high yield of wire rods (up to 90%), this preparation method uses asbestos boards to draw the rods horizontally, and the size of the rod blanks is relatively small. Unable to quickly solidify into an aluminum alloy billet, the aluminum alloy solution stays in the casting furnace for too long, which increases the burning loss and volatilization of alloying elements, resulting in uneven composition of the billet

Abstract

The invention discloses an aluminium alloy welding material rod blank production device. The aluminium alloy welding material rod blank production device comprises a melting reverberatory furnace, anelectromagnetic stirring device, a cooling circulation mechanism, an alloy crystallizer, a draft gear, and a wire collecting mechanism; the melting reverberatory furnace is connected with the electromagnetic stirring device; the copper alloy crystallizer is connected with the wire collecting mechanism through the draft gear; the alloy crystallizer is winded by the cooling circulation mechanism. The invention also discloses working process of the aluminium alloy welding material rod blank production device. The working process comprises following steps: 1, material preparation; 2, melting; 3, refining; 4, thermal insulation; 5, horizontal continuous casting guide rod; and 6, sampling inspection. According to the aluminium alloy welding material rod blank production device, advanced horizontal forging alloy crystallizer continuous casting up-draw technology is adopted, so that problems in the prior art that aluminium alloy tissue is not uniform, component is not uniform, a large amount of surface defects are caused, wire fracture is easily caused in drawing processing of welding wire, and batch production stability is poor are solved, rod blank diameter reaches 9.5 to 30mm, production efficiency is high, cost is low, welding wire quality is capable of reaching the advanced quality level of international welding wire of the same kind.

Description

technical field [0001] The invention relates to the field of aluminum alloy production, in particular to a production device for an aluminum alloy welding rod blank. Background technique [0002] With the rapid development of China's railway transportation, most of the rail vehicles have been made of aluminum alloy. Due to the high requirements on safety performance, there is currently no domestic enterprise that can independently produce its special aluminum alloy welding wire. At present, the high-end aluminum alloy used in domestic aluminum alloy components Almost all welding wires are imported, and the manufacturing process of high-quality aluminum alloy welding wires is mainly in the hands of developed countries such as Japan, the United States, France, and Canada, and these countries have implemented technological blockade measures against China, which has resulted in the inability to produce welding materials for important equipment in China. Self-guarantee. [0003]...
