Embodiment 1
[0032] This embodiment uses the process of the present invention to produce a large extra-thick slab with an external dimension of about 650×2500×3400mm and a unit weight of about 40 tons (t). The specific process is as follows:
[0033] The material of the large extra-thick slab is 16Mn. When molten steel is poured into the metal mold cavity for 1 hour, the solidified shell thickness of the large extra-thick slab is 100mm, and the shell thickness accounts for about 15% of the thickness of the large extra-thick slab. The thickness of the unsolidified area is 450mm. At this time, high temperature boxing is performed, and the outer surface temperature of the large extra-thick slab is as high as 1100°C. After boxing at high temperature, an insulation cover is added to the outer surface of the large extra-thick slab to slowly cool the large extra-thick slab, and the temperature of the outer surface of the large extra-thick slab is monitored. The cooling rate is about 8℃ / h to reach the...
Embodiment 2
[0036] This embodiment uses the process of the present invention to produce a large extra-thick slab with an external dimension of about 1000×2700×3300mm and a unit weight of about 60 tons (t). The specific process is as follows:
[0037] The material of the large extra-thick slab is EH36. When the molten steel is poured into the metal mold cavity for 2h, the solidified shell thickness of the large extra-thick slab is 200mm, and the shell thickness accounts for about 20% of the thickness of the large extra-thick slab. The thickness of the unsolidified area is 600mm. At this time, high temperature boxing is performed, and the outer surface temperature of the large extra-thick slab is as high as 1050°C. After boxing at high temperature, spray forced cooling on the outer surface of the large extra-thick slab to monitor the temperature of the outer surface of the large extra-thick slab. The cooling rate is about 110℃ / h until the large extra-thick slab is completely solidified.
