The invention provides a hot rolling titanium plate production method and system. The method includes the steps of firstly, heating a titanium plate blank, and feeding the same to a coarse rolling device after iron oxide generated by a furnace is removed; secondly, by the coarse rolling device, coarsely rolling the titanium plate blank to allow the thickness of the middle of the blank to 25-40mm, and then feeding the same to a hot coil box; thirdly, uncoiling with an uncoiling arm, using a head cutting flying shear to cut the irregular head into an arc shape when the head of the titanium plate blank is guided out, and then feeding the same to a fine rolling machine set for fine rolling; fourthly, continuously rolling the titanium plate blank into finished titanium strips through the fine rolling machine set which comprises seven total hydraulic four-roll rolling machines, and feeding the strips to a laminar cooling device for cooling; fifthly, coiling the titanium strips in a coiling machine to form titanium strip coils. The method has outstanding advantages that the method is simple and high in automation level, and yield and production efficiency of the titanium strip coils can be increased by accurate control of each link.
