Abstracts: IN LAXCON STEEL LTD a scrap metal are melted in high temperature furnace, a temperature near about 1500°c to 1600°c.After this melted metal bring out to Continuous Casting Machine through ladder ,then this mould of metal poured into tundish car machine. There are stages in machine like approl, intermediate section, withdrawal, auto cutter machine. But quality problems such as Cracks, Rhomboidity, Porosity, Lapping, seems Crack, Piping, Centre Looseness, Ovality, Blow holes, Pin holes and Breakouts are often observed in continuously cast steel billets. These defects create a problem in metal which is cast. On the one hand fundamental knowledge about heat transfer, solidification and mechanical behavior of steel was applied to identify the origin of a quality problem in the process. We finally study about Cracks and effect of cracks and also find solution to reduce Transverse cracks.
