Operation Parameters and Structural Optimization of a One-way Spiral Casting Roller

In this paper, the operation parameters of a one-way spiral flow casting roller were simulated. Varies optimization proposals on the casting roller were brought out mainly focusing on the inlet and outlet cavities. Both the inlet pressure and drum rotational speed was found having direct influence on water delivery capacity. The water delivering capacity was increased when the inlet pressure was rising without varying the total pressure loss of the system. The water delivery capacity of the system was dropped after the initial growth with the increasing drum rotation speed. Study on operation parameters can provide technical guidance for the actual operation of casting roller. Additional guide vanes in the water inlet and outlet cavities were designed to improve the capacity of water delivery. The total pressure loss of optimized structure was reduced by 10%. The total water supply and pressure loss of the new designs were better than those of the current structure under the same conditions. Adding the vanes in outlet cavity was found having the most outstanding effect. In actual operation, the water supply pressure and the drum speed should be comprehensively determined to make the system more energy efficient
