Example Embodiment
[0034] Example one:
[0035] Production of TC4 hot-rolled plates with a thickness of 10.5-23.5*200-1200*500-2000mm.
[0036] ①The size of the lower substrate is 110*1300*3000mm, the size of the upper substrate is 200*1300*3000mm, the surface of the upper and lower substrates is milled, the roughness is 3.2um, and the unevenness is 2mm / M.
[0037] ②On the lower substrate, place 1 sheet of 22*1200*2000mm horizontally from bottom to top in the first stacking mode, and place 4 sheets of 23.5*600*500mm horizontally in the second layer splicing mode, and the third layer splicing horizontally Place 4 plates of 10.5*600*500mmmm, the total thickness of the plates is 56mm, the thickness of the lower substrate + the thickness of the plates is 166mm.
[0038] ③The lower substrate and the stacked plates are placed horizontally in a heating furnace, and the upper substrate is also heated with the furnace, at a rate of 1.5mm / min, rapidly rising to 880°C and holding for 5 hours for solution.

Example Embodiment
[0047] Embodiment two:
[0048] Production of new hot-rolled titanium alloy plates with a thickness of 9.5-22.5*200-1200*500-2000mm.
[0049] ①The size of the lower substrate is 110*1300*3000mm, the size of the upper substrate is 200*1300*3000mm, the surface of the upper and lower substrates is milled, the roughness is 3.2um, and the unevenness is 2mm / M.
[0050] ②On the lower substrate, 4 pieces of 22.5*600*500mm plates are placed horizontally from bottom to top by splicing the first layer, 2 pieces of 10*1200*2000mm plates are placed horizontally by stacking on the second layer, and the third layer is spliced Place 8 plates of 9.5*600*500mmmm horizontally. The total thickness of the plates is 61.5mm, and the thickness of the lower substrate + the thickness of the plates is 161.5mm.
[0051] ③The lower substrate and the stacked plates are placed horizontally in a heating furnace, and the upper substrate is also heated with the furnace, at a rate of 1.5mm / min, rapidly rising to 920°C ...
