Abstract
Problem Statement (Relevance). The article discusses the technologies and units of the continuous casting and deformation machine (CCDM) working with liquid metal. The development of technology and CCDM units working with liquid metal creates the conditions for effective formation of the blank before its going through the CCDM and determines the efficiency of the deformation process and the quality of the subsequently continuously cast blank. The analysis of the specifics of liquid steel going through from the teeming hole of the intermediate ladle into the mold made it possible to choose the rational parameters of the location of the machine equipment. Objectives. It is required to rationalize the technologies and units of the CCDM using the modernized mold designs and simulation results. Methods Applied. The basic laws of the mechanics of the liquid steel motion such as a Newtonian fluid located in the temperature range determined by the conditions of steel casting are applied. A software product based on the use of the finite element method in fluid mechanics problems is used. Originality. For the first time, the parameters of the liquid steel motion in CCDM units that determine the parameters of the blank before deformation in the secondary cooling zone of the machine are considered. A mathematical model of the liquid metal motion in the process of complex casting and deformation in CCDM has been developed. Results. The article gives recommendations for rationalizing technologies and modernizing units to ensure the technological process of deformation. The necessary parameters of the technological process of continuous casting and deformation, organized in a single process of obtaining a cast blank, are determined. Practical Relevance. A method for assessing the joint operation of CCDM units that ensure the liquid metal motion is presented. Rational parameters of the location of machine units for the effective organization of the process of obtaining a blank on the machine are determined.
