1. Cracking during Continuous Casting of Steels : Analysis tools and procedures to identify their causes on microalloyed steel slabs
Abstract : Transverse corner cracks are one of the most common but complex defects formed in microalloyed steels during continuous casting (CC). Such cracks are detrimental because it leads to a loss in productivity with a great impact on environment, energy and economics for several steel making companies all over the world. READ MORE

2. A Study of the Initial Mould Filling during Up-hill Ingot Casting
Abstract : The fluid flow in the mould during up-hill teeming is of great importance for the quality of the cast ingot and thereby the quality of the final steel products. At the early stage of the filling of an up-hill teeming mould, liquid steel flows with a high velocity from the runner into the mould. READ MORE

4. On Tool Failure in Die Casting
Abstract : Die casting is a very cost-efficient method of forming thin-walled and complex near net-shaped products with close geometric tolerances and good surface finish. A permanent die tool is used to make large quantities of identical products. The performance and tool life are limited by several mechanisms, e.g. READ MORE
