No notes for slide. Continuous casting 1. The casting will keep traveling downward, its length increasing with time.
New molten metal is constantly supplied to the mold, at exactly the correct rate, to keep up with the solidifying casting. Industrial manufacture of continuous castings is a very precisely calculated operation. Molten metal, from some nearby source, is poured into a tundish. A tundish is a container that is located above the mold,it holds the liquid metal for the casting 2. This particular casting operation uses the force of gravity to fill the mold and to help move along the continuous metal casting.
The tundish is placed about feet above the ground level. The tundish is constantly supplied with molten steel to keep the process going. The whole process is controlled to ensure there is smooth flow ofmolten steel through tundish.
Further, the impurities and slag are filtered in tundish before they move into the mold. The entrance of the mold is filled with inert gases to prevent reaction of molten steel with the gases in the environment like oxygen.
The molten metal moves swiftly through the mold and it does not completely solidify in it. The entire mold is cooled with water that fl ows along the outer surface. The metal casting moves outside the mold with the help of different sets of rollers. While one set of rollers bend the metal cast, another set will straighten it.
This helps to change the direction of flow of the steel slab from vertical to horizontal. Continous and capable cooling of mould is required. Just simple shapes can be cast. Last capital investment is necessary to set up process. Not proper for small scale production. Require large ground space.
A great tonnage of continuous casting is done using cast steel. Other metals that are continuous casting are copper, aluminum, grey cast iron s, white cast irons, aluminum bronzes, oxygen-free copper, etc. Metals are cast as ingot for rolling, extrusion, or forging, and long shapes of simple cross section are cast as round, square, hexagonal rods, etc. Total views 7, On Slideshare 0.
