description	The invention provides a high-casting-speed non-stop water-free top seal method of a wide and thick plate continuous casting machine, and belongs to the technical field of a continuous casting process. The method comprises the steps that S1, according to the tundish actual measurement tonnage and the actual liquid face height, a tundish casting sped is reduced in an accelerated manner; S2, the casting speed is kept for blank casting, the liquid face height is determined, and a plug bar is closed; S3, a layer of cooling steel square block is loaded on a molten steel surface, which is not solidified, in a crystallizer; S4, a layer of cooling metal particles are loaded in the crystallizer; and S5, when a final blank is on a crystallizer lower opening, the speed is increased in an acceleratedmanner to the target casting speed. According to the high-casting-speed non-stop water-free top seal method of the wide and thick plate continuous casting machine, a traditional water fetching top seal process can be complete
