Currently, mathematical modeling applying numerical methods is widely used in the study of metallurgical processes, including metal casting processes in continuous-casting machines. The authors developed a new technology and device for casting metal into a continuous-casting machine mold and metal mixing using the effect of a rotating closed-bottom submerged nozzle with eccentric holes. The theoretical study of processes of mold filling with molten metal was carried out applying a proven numerical method and a special software package. A calculation program was developed based on the numerical schemes and algorithms. The results of calculating metal casting into a rectangular mold are presented as an example. The calculation results are provided in the form of molten metal flow patterns in various sections of the mold.

“…In order to produce large diameter billets, continuous casting machines (CCM) are equipped with additional tools to expose the solidifying continuously cast billets to external inputs. The efficiency of electromagnetic stirring of a solidifying continuously cast billet is shown in the works [1][2][3][4] which demonstrate that metal quality can be improved by various methods of electromagnetic stirring.…”

The paper contains a thermal performance calculation which proves that the basic items of heat loss include heat losses spent heating the hot top casing and lining. If thermal insulation is used, losses through the metal mirror do not exceed 3.5%. It is shown that in order to improve hot top efficiency it is required to minimize losses spent on heating the lining and the hot top casing; consequently, the amount of the heat transferred to the solidifying ingot can be increased. The assessment of the performance of the hot top with various heat insulators proves that the most efficient one is the untapered (straight) hot top insulated with the MKPB-340 inserts: in this case the quantity of heat transferred to the chill amounts to 70% of the overall value. An alteration of the hot top insulation type and geometry makes it possible to improve hot top thermal performance. As a result, the heat center of the solidifying ingot shifts to the hot top. Consequently, the shrinkage of solidifying steel is efficiently compensated, which decreases the physical and chemical heterogeneity of the billets produced and improves the ingot-to-product yield.
