Abstract：Abstract：Twin-roll casting is an advanced continuous casting technology, and the flow pattern of the distributor directly affects the quality of its products. Considering distributor, roller sleeve, molten pool, material nonlinearity and complex boundary conditions at the same time, the numerical model of fluid-solid-heat coupling of twin-roll casting was established, and the distribution of flow field and temperature field in the molten pool was researched. The results show that there are four vortices in the molten pool below the side of the distributor and near the side opening, and there is a concave high temperature area on the side close to sealing plate. The width of opening on both sides of the distributor has a great influence on flow field and temperature field of the molten pool. When the widths of the side and end openings are 12 mm and 22 mm respectively, the position distribution of the Kiss point of the molten pool is ideal. The width of the opening on both sides of the distributor is adjusted correspondingly, which is beneficial to control position height of the Kiss point of the molten pool.
