Studying as - Cast Microstructure of the Cold Core (cc) Ingot
X. J. Zhang, C. J. Xu (Corresponding Author), Z. Y. Wang, J. Li, L. W. Zhang, X.D. Peng. School of Materials and Metallurgy, University of Science and Technology Liaoning, China In this study, the mechanism of the formation in structure of Cold Core ingot which is prepared by cold core casting method in lab is studied. The structure of the CC ingot is obtained by optical microscopy and macrosco...
متن کاملCooling rate optimization of as-cast consciously cast steel
Abstract: A combination of a finite element method (FEM) algorithm with ANSYS codes and post image processing of NDT ultrasonic images along with laboratory cooling experiments and microstructural analysis provide a guideline to determine the optimum cooling rate for any grade of steel in which the highest productivity can be achieved without any degradation of the cast steel products. The sugg...
متن کاملSimulation of Convection and Macrosegregation in a Large Steel Ingot
segregates. Although good agreement with experiments was MACROSEGREGATION in large steel ingots is one achieved, the model relied on many approximations (such of the most well-known and now classical problems in the as estimating the flow velocities). It should also be menfield of solidification and casting.[1] It arises from the relative tioned that many models have appeared in the literature ...
متن کاملSelection of Mould Fluxes for Production of High Quality Steel Ingots
Introduction Ingot products account for 8.3% of the total crude steel produced in the world. It is produced either by top pouring or bottom pouring of the liquid in the moulds. The increasing demand for quality steels led to the evolution of bottom pouring technology for casting of steel ingots. This process constitutes of a set up involving pouring sprue and runner system to deliver liquid ste...
متن کاملThe Effects of Mould Materials on Microstructure and Mechanical Properties of Cast A356 Alloy
Abstract In this study, the effects of mould materials on microstructure and mechanical properties of cast A356 Al alloy were investigated. The alloy was poured into three different moulds. Then the samples were homogenised and applied T6 heat treatment. The optical, Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) studies were made. Secondary dendrite arm spacing (SD...
