Main Process and Technical Features of Continuous Billet Caster
The technological features of the round billet continuous caster mainly include the following aspects:
First, the radius of the arc is 13 meters.
Because the size of the arc radius can be directly matched with a variety of different steel grades for flexible production, the production range of continuous billet caster is greatly widened. By improving the quality level of internal billet, not only the control effect of the caster is effectively improved, but also the production flexibility is improved, and the comprehensive benefit of the enterprise is promoted.
Second, the square billet and round billet can be produced together.
Due to the strong flexibility of the equipment and the corresponding technical adjustment of different customers in the actual production, it highlights the characteristics of the square and round billet continuous caster. Due to the flexible exchange, not only the manufacturing radius of the round billet can be improved, but also the square billet production can be carried out, so that one machine can be used for multiple purposes, greatly expanding the scope of use. Thus, the cost of production and purchase is saved for the enterprise.
Third, automatic protection technology.
Since the automatic equipment is added to the continuous billet caster, the distribution uniformity of the protective slag is realized by effectively controlling the adding speed of the protective slag. In addition, the application scope of the automatic protection technology also includes improving the internal lubrication conditions of the mold and promoting the overall efficiency of production, so as to reduce the production risk and improve the overall profit.
Fourth, automatic mixing technology.
The internal part of the arc caster of the square and round billet can realize the synchronous production of the surface and internal structure of the billet by setting the internal hollow crystallization electromagnetic stirrer, thus greatly improving the internal quality of the billet. Because the application principle of the automatic stirring technology mainly relies on electromagnetic stirring, so it reduces energy consumption. Compared with the traditional use mode of the continuous casting machine, the electromagnetic stirrer at the end of the secondary cooling has the effect of expanding the axial crystal rate of the billet, which has certain effect on improving the internal loose environment of the billet and improving the central segregation effect of the billet.
