Packing type steel band bending characteristic of casting machine

Packaging steel strip casting machine is characterized by: curved slab in the whole solidification process has been a natural curve. Only in the la area correction is forced to straightening and fully set. However, due to take proper roller applied external force when the shell strength is low, therefore, in order to prevent slab cracks, it should reduce each roll force on the shell, which appeared more roll straightening. Each roll force of slab reduced, and the number of rolls increased, also can ensure that the overall casting straightening force. In addition, the high speed casting caused by the increase of the length of the liquid phase, can prolong level of casting machine parts. For straightening is concentrated in the circular and linear part of the intersection of curved casting machine, due to the force of the slab under is very big, so the risk of internal crack, therefore the multipoint straightening model. In order to avoid the slab crack, there is also a kind of way is to use & the other; The compression casting & throughout; The way. Make the cast also often to offset the effect of compression stress generated when the bending tensile stress.
