Double-roller cast rolling 1100 aluminum alloy casting nozzle structure

The utility model relates to the technical field of steel casting and rolling, in particular to a double-roller casting and rolling 1100 aluminum alloy casting nozzle structure. ANSYS FLUENT is adopted to carry out finite element simulation on a double-roller casting and rolling 1100 aluminum alloy Hunter type casting nozzle, the influence of a casting nozzle cavity structure on an aluminum melt flow thermal field is studied, and simulation optimization design and experimental verification of improving an edge check block, increasing the size of a main shunting block and increasing a fillet are carried out on the casting nozzle structure. Research results show that the mathematical relationship between the viscosity eta of the aluminum melt and the temperature T within the temperature range of 660-700 DEG C is eta = 4.7892 * 10 exp (3959.4208/T). Before optimization, the flow velocity and the temperature of aluminum melt in a casting nozzle cavity are not uniformly distributed, and a low-temperature vor
