¿Qué es una rueda curva?

El cristalizador de la máquina de colada continua de arco es curvo y el rodillo de presión de la segunda zona fría está instalado en un cuarto de arco. La losa se endereza en el punto tangente de la línea central vertical y luego se corta en una longitud fija, desde la dirección horizontal. La pieza en bruto se dibuja así, de modo que la altura de la máquina de colada sea sustancialmente igual al radio del arco. Las principales características de esta máquina de colada continua son:

1 Because it is arranged in the range of 1/4 arc, its height is lower than that of vertical and vertical bending. This feature makes its equipment lighter, the investment cost is lower, and the equipment is easy to install and maintain. And thus is widely used.

2 Due to the low height of the equipment, the static pressure of the molten steel that the slab is subjected to during the solidification process is relatively small, which can reduce the internal crack and segregation caused by the deformation of the bulge, which is beneficial to improve the quality of the slab and increase the pulling speed.

The main problem of the 3 arc continuous casting mechanism is that the non-metallic inclusions tend to accumulate toward the inner arc side during the solidification process, which tends to cause uneven distribution of inclusions inside the casting blank. In addition, due to the uneven cooling of the inner and outer arcs, It is easy to cause segregation at the center of the slab and reduce the quality of the slab.
