Automatic Detection and Localization of Surface Cracks in Continuously Cast Hot Steel Slabs Using Digital Image Analysis Techniques
Quality inspection is an indispensable part of modern industrial manufacturing. Steel as a major industry requires constant surveillance and supervision through its various stages of production. Continuous casting is a critical step in the steel manufacturing process in which molten steel is solidified into a semi-finished product called slab. Once the slab is released from the casting unit, th...
متن کاملPhysical Modeling of Steel Delivery during Thin Slab Continuous Casting
A full scale physical model of a thin slab caster with a four-hole design submerged entry nozzle (SEN) was constructed. On the basis of the dimensionless Reynolds and Froude similitude criteria, the fluid flow in a full-scale model is similar to that of the actual system and, hence, the data obtained from the water model can be applied to the actual system. In order to determine the optimum ope...
متن کاملMathematical Modeling of Heat Transfer for Steel Continuous Casting Process
Heat transfer mechanisms and the solidification process are simulated for a continuous casting machine and the geometric shape of the liquid pool is predicted considering different conditions. A heat transfer and solidification model is described for the continuous casting of steel slabs. The model has been established on the basis of the technical conditions of the slab caster in the con...
متن کاملUsing Finite Point Method for the Numerical Simulation of Heat Transfer Coupled with Microsegregation during Continuous Casting
In the present work, a meshless method called Finite Point Method (FPM) is developed to simulate the solidification process of a continuously cast steel bloom in both primary and secondary cooling regions. The method is based on the use of a weighted least-square interpolation procedure. A transverse slice of the bloom moving at casting speed is considered as the computational domain and two di...
متن کاملOn-line Detection of Quality Problems in Continuous Casting of Steel
Quality problems in continuous casting of steel can be identified as they occur by monitoring mold signals (level sensor, thermocouples in the mold walls, friction etc.) and taking appropriate action (such as slowing casting speed, changing taper, changing a clogged nozzle, or later visual inspection of the surface for possible downgrading. Surface depressions and groups of deep oscillation mar...
