Arc Continuous Caster for Square and Round Billet
Main Technological Features of Arc Continuous Caster
The process characteristics of arc continuous caster for square and round billet mainly include the following aspects:
Primero, the arc radius of the arc continuous caster is 13 metros. Porque el tamaño del radio del arco se puede combinar directamente con una variedad de grados de acero diferentes para una producción flexible, the production scope of the square and round billet caster is greatly broadened. By improving the quality level of the internal billet, no solo se mejora efectivamente el efecto de control del lanzador, but also the flexibility of production is enhanced, y se promueve el beneficio integral de la empresa.
Secondly, square billet and round billet can be produced together. Due to the strong flexibility of the equipment and the need to adjust the technology for different customers in actual production, the characteristics of the square billet caster are highlighted. Debido al intercambio flexible, not only the production radius of the round billet can be improved, but also the production of the square billet can be carried out, para que una máquina pueda usarse para múltiples propósitos, ampliando enormemente el alcance de uso, So as to save production and procurement costs for enterprises.
Tercero, tecnología de protección automática. Due to the automatic equipment added to the billet caster, the distribution uniformity of mold flux can be achieved by effectively controlling the adding speed of mold flux. Además, the application scope of automatic protection technology also includes improving the lubrication conditions inside the mold and promoting the overall efficiency of production, para reducir el riesgo de producción y mejorar el beneficio general.
Cuatro, tecnología de mezcla automática. The inner part of the square and round billet arc caster is equipped with a built-in hollow crystallization electromagnetic stirrer to realize the synchronous production of the surface and internal structure of the billet, mejorando así en gran medida la calidad interna del tocho. The application principle of automatic stirring technology mainly relies on electromagnetic stirring, so the energy consumption is reduced. Compared with the traditional use mode of the continuous caster, the electromagnetic stirring at the end of secondary cooling can also expand the axial crystal rate of the billet, which has a certain role in improving the loose environment inside the billet and enhancing the effect of central segregation of billet.
Process Parameters of Billet Caster
As an advanced continuous caster, the square billet caster belongs to the full arc continuous caster equipment type. Al mismo tiempo, the arc radius is 13 metros, and the metallurgical length can reach as much as 28 metros. Además, due to the flow spacing of 1200mm, the casting process quality control level of the whole equipment is relatively high. According to different process requirements, the adjustable range is also large. The pulling speed is 0.5 ~ 3.5m/min. The machinable section of the square billet and the round billet is basically 200mm, and the annual production capacity is higher no less than 1.5 millones de toneladas. Al mismo tiempo, the metal recovery rate is effectively improved through the overall design of the equipment 10%.
