Prediction of Casting and Solidification of Slab Steel Ingot

Popis výsledku v původním jazyce

The main problem in production of forgings from tool ste els, especially in the form of thick plates, blocks, and rods which are used for special machine components for demanding applications, is the inhomogeneous structure with segregations, cracks in segregations or complex type of non - metallic inclusions of M nS and TiCN type. These forgings are actually produced from conventional forging ingots. Due to the size of forgings, it would be interesting to produce these forgings from slab ingots. It is possible that production of forgings from slab ingots (which are distinguished by a characteristic aspect ratio A / B) would reduce the occurrence of segregations. The paper presents the verification of the production process of slab steel ingots in particular by means of numerical modelling using finite element method. The paper describes the pre - processing, processing and post - processing phases of numerical modelling. The attention was focused on the prediction of behavio u r of hot metal during the mo u ld filling, on verification of the final porosity, of the final seg regation and on prediction of risk of cracks depending on the actual geometry of the mould.
