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 continuou...

this paper describes the work done between iust and two iranian steelworks to evaluate and review the performance of mould fluxes in current use for continuous casting. calculations have been performed to compare actual values of powder consumption, viscosity and break temperature of the fluxes in current use with required values derived from published empirical rules for casting conditions. it...

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...

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...

Continuous casting is used to mass produce basic metals into long, semi-finished shapes with constant cross section, which are later processed into over 800 million tons of steel, 20 million tons of aluminum, and 1 million tons of copper, nickel, and other metal products in the world each year. Cross-sections can be rectangular, for later rolling into plate or sheet, square for long products, c...

usd7 is one of the steel products of isfahan steel company. it is cast in continuous casting moulds and rolled up to a rod of 5 mm diameter. finally, it is wire drawn up to 3 mm and used as welding electrodes. this steel contains 0.05 to 0.09 wt. % carbon. the acceptable limit of the aluminium in this class of steel is less than 0.003 wt%. therefore, it is categorized as rimmed steel. during fo...

the main objective of this project was to investigate the behavior and the damaging effects of hot tear segregationsin the continuously cast steel blooms on the final product quality. to achieve this aim, plant data from three differenttypes of steels were used. investigations using the scanning electron microscope (sem) equipped with energydispersive x-ray spectroscopy (eds) probe and metallog...

1 The high cost of empirical investigation in an operating steel plant makes it prudent to use all available tools in designing, troubleshooting and optimizing the process. Physical modeling, such as using water to simulate molten steel, enables significant insights into the flow behavior of liquid steel processes. The complexity of the continuous casting process and the phenomena which govern ...

Continuous casting is used to solidify most of the 750 million tons of steel produced in the world every year. Like most commercial processes, continuous casting involves many complex interacting phenomena. Most previous advances have been based on empirical knowledge gained from experimentation with the process. To further optimize the design and improve the continuous casting process, mathema...
