Continuous casting device, casting bar equipped with continuous casting device and manufacture method thereof

Abstract

The invention provides a continuous casting device, a casting bar equipped with the continuous casting device and a manufacture method thereof, wherein harmful impurities in melts can be removed and casting bars of high quality can be obtained. The continuous casting device (1) comprises a maintenance furnace (3), an intermediate pot (7) and a liquid feeding pipe (6). Melt (M) is stored in the maintenance furnace. The melt (M) stored in the maintenance furnace is provided for the intermediate pot (7). One end of the liquid feeding pipe is installed on the maintenance furnace (3) and the other end thereof is installed on the intermediate pot (7). The melt (M) in the maintenance furnace (3) is provided for the intermediate pot (7). The melt is casted into casting ingots by the continuous casting device. A melt path (11) for the flowing of the melt (M) is formed by the maintenance furnace (3), the intermediate pot (7) and the liquid feeding pipe (6). A filter (F) for filtering the melt (M) is arranged in the melt path (11). A pressurizing device (2) for pressurizing the melt (M) in the maintenance furnace (3) is arranged in the maintenance furnace (3).

Description

technical field [0001] The present invention relates to a continuous casting apparatus for continuously casting metal cast bars (ingots) for, for example, vehicle parts, engine parts, aircraft parts, or machining or plastic working, and use of the continuous casting A cast bar manufactured by the device and its manufacturing method. Background technique [0002] At present, in DC casting, a molten magnesium alloy is supplied from a holding furnace to a casting mold via a tundish, and the molten metal is cast and solidified by primary cooling of the casting mold and secondary cooling by direct water cooling. The direction is drawn to form a cast rod. [0003] The molten magnesium alloy has strong oxidizing property, and the specific gravity of the oxide of the magnesium alloy is larger than that of the molten metal, so it will sink to the bottom of the crucible. Therefore, the work of separating and removing oxides from the crucible is not easy. Furthermore, since an oxide...

Problems solved by technology

However, when the opening of the mesh of the filter is miniaturized, the flow resistance (flow resistance) when the melt passes through the filter increases with the miniaturization.

Therefore, in the conventional casting method, it is difficult to miniaturize the opening of the filter, and it is difficult to obtain a high-quality casting rod.
