This paper describes activities relating to mold level control in continuous casting process as case examples of our process control solution business, in which we clarify and evaluate the process phenomena and design the control system. Initially, a mold level control model has been formulated by fluid flow analysis technique that evaluates molten steel flow in the mold quantitatively. The mod...

this paper, largely motivated by hoey (2001), revisits the issue of written discourse analysis and, in particular, the problem-solution pattern. much discussion embarrasses the way in which texts are pro-duced and understood. the different functional approaches include halliday and hasan’s approach, van dijk’s process-oriented approach, the procedural approach of de beaugrande and dressler, and...

For a sample steel casting of cylindrical shape that was cast in metallic mould, the analysis influence and importance main boundary condition on simulation accuracy temperature field system casting-mould-environment performed. this system, frame bottom top casting, casting-mould interface analysed. As comparing quantity for accuracy, time-dependent (by means isotherms) mould total solidificati...

In this study, corrosion behaviour of A356-10 vol.% SiC composites casted by gravity and squeeze casting is evaluated. For this purpose, prepared samples were immersed in HCl solution for 1h at open circuit potential. Tafel polarization and electrochemical impedance spectroscopy (EIS) were carried out to study the corrosion resistance of composites. The Tafel polarization and EIS studies of ...

The paper discusses a 3D numerical solution of the inverse boundary problem for a continuous casting process of alloy. The main goal of the analysis presented within the paper was to estimate heat fluxes along the external surface of the ingot. The verified information on these fluxes was crucial for a good design of a mould, effective cooling system and generally the whole caster. In the study...

polyurethane/zeolite 13x nanocomposite films were fabricated using solution casting method. the synthesized nanocomposite films were structurally characterized using sem, tga and tensile analysis. sem images showed appropriate distribution of nanocrystalline zeolite particles within polyurethane matrix. better thermal stability of nanocomposite films in comparison to neat polyurethane was shown...

Steel-making and continuous/mould casting are the key processes of modern iron and steel enterprises. The continuous and mould casting schedule of mixed whole/half charging plan is the bottleneck for the steel-making and continuous/mould casting process. However, it is very difficult to find a solution against the characteristics and complicated environment. This paper proposed a heuristic batc...
