A cooling process for producing high-magnesium aluminum alloy welding wire billets by continuous casting and rolling

Abstract

The invention relates to a cooling process for producing a high-magnesium-aluminum alloy welding wire blank through a continuous casting and rolling method. The process comprises the following steps:(1) raw material selection and weighing; (2) refining: adding an aluminum ingot in a melting heat-insulation furnace and melting, and then refining; (3) degassing and deslagging: carrying out degassing and deslagging through online refining and filter equipment; and (4) casting and cast-rolling: casting to obtain an ingot, and then conveying the ingot in a twelve-rack two-roll continuous rolling unit and carrying out cast-rolling; and carrying out online cooling on the alloy rod obtained through the cast-rolling through an emulsion. According to the process disclosed by the invention, the adverse influence of high temperature of the alloy rod in a winding process for the high-magnesium-aluminum alloy welding wire blank (alloy rod) is solved, the working efficiency and the stability of thesubsequent winding working are ensured, and the high-temperature damage of the high-temperature aluminum alloy rod to equipment is reduced; and the surface of the aluminum alloy rod can be cleaned toimprove the surface quality while the aluminum alloy rod is cooled to improve the performance stability, so that further improvement for the machining quality is promoted.
