Abstract
A thin metal strip continuous casting method using momentum flow distribution, comprising the steps of: adjusting the position of a flow distribution device (), and starting a double-roller thin strip continuous casting apparatus; molten metal () forming a uniform sheet-shaped molten metal flow () having an initial momentum after the molten metal () passes through the flow distribution device; the sheet-shaped molten metal flow entering a molten pool () at a superheat degree of 50-100° C. and an initial velocity of 0.5-2 m/s, wherein the flow distribution device is spaced apart from the molten pool; under the action of the initial velocity of the molten metal and in the molten pool, forming a whirlpool, which is adjacent to surfaces of two cooling rollers and has a momentum stirring action; and completing the solidification of the molten metal under the momentum stirring action of the whirlpool along with the rotation of the two cooling rollers. In the method, a whirlpool, which is adjacent to surfaces of cooling rollers and has a momentum stirring action, is formed in a molten pool by means of the kinetic energy of molten metal, such that equiaxed crystals can be prepared when a superheat degree is as high as 50-100° C., and the proportion of equiaxed crystals can be increased to 100%, thereby refining crystal grains and alleviating segregation.
