Continuous Casting Billet

The temperature field of continuous casting billet (CC-billet) is important to carry out the research on direct rolling of free-heating (DROF). The solidification and the heat transfer process of CC-billet from crystallizer to cutting point were studied by finite element method (FEM).The casting speed was improved in order to get reasonable temperature field during DROF.

An inverse technique based methodology for the optimal control of the solidification front motion in the continuous casting of pure metals with temperature-dependent material properties is proposed. In this method, to achieve specific mechanical and metallurgical properties of the final product, a predefined motion of the solidification front is selected. A history of the heat flux on the fixed boundaries of the problem is then computed, which would result in an actual motion of the solidification front representing the best match for the desired one. A sensitivity analysis of the inverse problem is efficiently carried out by a truly meshless method. The proposed inverse technique is applied for the design of the continuous casting of pure metals with temperature-dependent thermo-physical properties. The efficiency of the proposed method is demonstrated through some numerical examples.

The article is devoted to calculations of load on rollers of a curvilinear continuous casting machine during bending of the ingot in the levelling section. The calculation takes into account the elastic and plastic characteristics of metal and the flexibility of the roller apparatus. Determination of load on rollers together with meeting other requirements such as reducing the cooling water consumption, minimizing the energy consumption enables optimizing the technology of slab cooling in the secondary cooling zone (SCZ) and obtaining metal of the required quality.

<p>In this study, new theoretical conceptions have been developed about an impurity segregation mechanism at the time of alloy solidification considering present microvolumes with different chemical compositions during alloy solidification. It has been concluded that this conception allows to establish and optimize technologic parameters that influence the production of the main types of macro-heterogeneity. The derived model conceptions have confirmed the final condition of real continuous casting billets by using the advanced analyzing methods. </p><p>Highlights </p><p>· The quasi-equilibrium theory used to study the hardening processes of alloys has been expanded and improved.<br />· The development of a numerical model for macrosegregation impurities in solidifying continuous casting billet is suggested.<br />· The adequacy of the developed model is checked under the industrial conditions using comparison theoretical<br />· calculations and practical data.<br />· The results and developments that are obtained are discussed.</p>
