Description of Semi-continues casting for magnesium
It is also called the vertical direct chill casting (DCC),which is the preferred method that is used universally for casting of large cross-sectional slabs and round billets of various aluminum alloys . This method is also used to cast other non-ferrous alloys, such as magnesium alloys, copper alloys, zinc alloys, etc. The casting process in this method starts by feeding the melt through some form of a melt delivery system into an open-ended water-cooled mold. Initially, the bottom end of the mold is kept-plugged by a starter metallic block which is fitted with a hydraulic ram at the bottom. When molten metal comes in contact with the cooled mold walls and the upper-surface of the bottom block, it solidifies and forms an embryonic shell containing liquid metal within the shell. Once a pre-determined height of liquid metal is filled within the mold cavity, the starter block holding the shell-liquid assembly is slowly moved downward toward the casting pit with the help of the hydraulic ram. The speed of the starter block is then gradually increased until a constant casting speed is reached. Once the cast is out of the mold, it is further cooled by spraying water coming out from the bottom of the mold onto the outer surface of the embryonic ingot. The cooling that takes place in the mold region is called primary cooling where only 10 to 15% of the total heat content of the ingot is removed. The heat extraction from the ingot that takes place below the mold is called secondary cooling where 85% to 90% of the total heat content is extracted. In a typical DCC process, it takes about five to ten minutes to reach a quasi-steady state. Depending on the casting speed (which normally varies between 40 and 100?mm/min for magnesium alloys) and the size of the cast, the total operation of this semi-continuous process usually lasts for about 100 to 120 minutes .
