[0001] The utility model relates to the technical field of magnesium alloy cold-drawn tube processing, in particular to a magnesium alloy cold-drawn tube quenching device. Background Art

[0002] Quenching is a heat treatment process that involves heating a material to or above the critical temperature, holding the temperature for a period of time to fully or partially austenitize it, and then rapidly cooling it to below Ms (or isothermally near Ms) at a cooling rate greater than the critical cooling rate to undergo martensite (or bainite) transformation.

[0003] In the prior art, the cold-drawn tube is conveyed into the heating cylinder through the feed tube, and the heating tube is operated to generate heat to heat the cold-drawn tube. After being heated to a preset temperature, the heating is stopped for insulation. The roller conveys the heated and insulated cold-drawn tube under the operation of the first motor, and the cold-drawn tube is discharged through the discharge pipe for cooling.
