Continuous casting machine process pdf. 411 increase in casting speed extending the machine length is an effective measure to increase the casting speed of a continuous caster. Prior to the introduction of continuous casting in the 1950s steel was poured into stationary molds to form ingots. Recent innovations have transformed the continuous casting of steel into a sophisticated high technology process that makes 90 of steel in the world today. Continuous casting presently responsible for over 98 of ja. The strand withdrawn from the mould should have a. This invention relates to a continuous casting process and more particularly it relates to the prevention of harmful surface deposits on castings produced by the continuous casting of metal alloys having as one element a metal of relatively high vapor pressure which is segregated from the metal during casting and periodically reabsorbed on. Constant size casting by the process. The great number of phenomena in the continuous casting process of steel especially of large size cast slabs necessitates the need for continuous research in particular in a cast of new steel grades. 1 center 50 200 ton ladles of molten steel are supplied periodically to the caster from the steelmaking process. Process conditions such as the start and the end of cast ing must be included in the model. The steel solidifying process during continuous casting starts in the mould where between 15 and 30 of total heat is abstracted. Continuous casting manufacture is different from other metal casting processes particularly in the timing of the process. The continuous casting process for steel is shown in fig. In other casting operations the different steps to the process such as the ladling of metal pouring solidification and casting removal all take place one at a time in a sequential order. The tundish holds enough metal to provide a continuous flow to the mold even during an exchange of ladles which are supplied periodically from the steelmaking process.

Continuous casting machine pdf. These must be correlated with the continuous casting machine technological parameters. Since then continuous casting has. Conduction radiation and convection 9 11. 2in this process molten steel flows from a ladle through a tundish into the mold. Describing the heat transfer model in the continuous steel casting process is a complex task as all three mechanisms of heat transfer occur in this process. Thus there is a need for the formulation. Continuous casting also called strand casting is the process whereby molten metal is solidified into a semifinished billet bloom or slab for subsequent rolling in the finishing mills. The following processes influ. 1 second frame and the close up of the upper mold region is shown in fig.
