At present, a fixing mechanism is usually used to fix the casting nozzle. If a casting and rolling mill with narrow specifications (narrow size) is used to produce plates with wide specifications (wide size), the narrow casting and rolling must change the small size and flow casting nozzle used to a large size and flow casting nozzle. However, since the fixing mechanism used to fix the casting nozzle used in conjunction with the narrow casting and rolling mill cannot fix the large size and flow casting nozzle, the narrow casting and rolling mill cannot adjust the casting nozzle used according to demand to produce large plates of different sizes, which narrows the scope of application of the narrow casting and rolling mill, and its capacity utilization rate cannot be improved.
