Subsurface hook formation during initial solidification in the continuous casting mould degrades the quality of steel slabs owing to the associated entrapment of argon bubbles and non-metallic inclusions. To minimise hook depth and to improve slab quality, extensive plant experiments were performed and analysed to quantify the effect of casting parameters on hook characteristics using the no. 2...

Abstract: The horizontal continuous casting process has received a significant attention for near net shape casting of non ferrous metals and alloys. Numerical Simulation has been widely used for process design and optimization of continuous casting process. In the present study, a 3-dimensional heat flow model was developed to simulate the heat transfer and solidification in a horizontal b...

The yield-line method of analysis is a long established and extremely effective means of estimating the maximum load sustainable by a slab or plate. However, although numerous attempts to automate the process of directly identifying the critical pattern of yield-lines have been made over the past few decades, to date none has proved capable of reliably analysing slabs of arbitrary geometry. Her...

This paper presents the influence of polyolefin fiber on flexural and shear attitude flat slabs. Three slab sets (80 cm × 80 cm) were tested, each with a thickness 10 cm. In first set (S1), effect content behavior was considered. Therefore, four specimens cast, one which considered as control specimen no content, while other three included fibers at 0.5, 1, 1.5 percent total concrete volume. Th...

The statistics of extreme values (SEV) and the generalized Pareto distribution (GPD) are introduced to obtain predicted maximum carbon content represent macrosegregation degree along casting direction in continuous billets (represented by 82B cord steel). Subsequently, influence mechanism superheat on has been investigated. It’s found that SEV GPD methods can correctly results obtained method i...
