摘要： The present invention relates to a cooling apparatus and to a cooling method for an indirect extruder, wherein the technical aim of the present invention is to provide a cooling apparatus and a cooling method for an indirect extruder, which enable a cooling medium to flow through a stem and a die, and which directly inject the cooling medium into an extrudate in the die, to thereby prevent the temperature of the extrudate from excessively rising and thus improving the speed of extrusion. For this purpose, the cooling apparatus for an indirect extruder according to the present invention comprises a stem, a die and a billet. The stem has an outer surface on which a plurality of cooling medium injection ports are formed such that a cooling medium can be supplied therethrough, and has an interior in which a plurality of cooling medium conveying pipes are connected to the respective cooling medium injection ports to enable the cooling medium to flow toward the ends of the cooling medium conveying pipes. The die is connected to an end of the stem, and has an interior in which a plurality of cooling medium dispersing pipes are formed to disperse the cooling medium conveyed through the cooling medium conveying pipes, and has an outer surface on which a cooling medium dispersing groove is formed. The cooling medium dispersing groove has dispersing holes connected to the cooling medium dispersing pipes such that the cooling medium conveyed through the cooling medium conveying pipes is uniformly supplied to the cooling medium dispersing pipes via the dispersing holes. The billet is arranged at an end of the die to shape the extrudate that has been extruded through the stem and the die by indirect extrusion. The cooling medium cools the die while passing through the cooling medium dispersing pipes, and cools the extrudate while being directly injected into the extrudate after passing through the cooling medium dispersing pipes.

摘要： A horizontal continuous casting apparatus for continuously manufacturing a magnesium alloy plate and a method of manufacturing a magnesium alloy plate using the same. The horizontal continuous casting apparatus is structured such that the cross-sectional area of the plate is equal to or smaller than that of a melt inlet, and includes a cooling unit for indirectly cooling the melt using a cooling jacket provided to the outer wall of the mold and/or for directly cooling the melt through spraying of cooling water, and a drawing unit having a multi-step drawing cycle. Thereby, magnesium alloy plates having various sizes can be safely and continuously cast.

摘要： Provided is a magnesium alloy with remarkable ignition resistance and being excellent in both strength and ductility. According to the present invention, the magnesium alloy comprises 1.0-7.0 wt% of Al, 0.05-2.0 wt% of Ca, 0.05-2.0 wt% of Y, and the balance of Mg and inevitable impurities, wherein the content of Ca and Y is 0.1-2.5 wt% on the basis of the total weight of the magnesium alloy. According to the present invention, the magnesium alloy forms a dense composite layer serving as a protective film to be able to be melted, cast and processed in air or in the common inert atmosphere (Ar, N2) and to inhibit the spontaneous combustion of chips piled in a machining process due to having superior oxidation resistance or ignition resistance.
