Description
Technical Field
The invention belongs to the technical field of metal cooling equipment, and particularly relates to a sectional type continuous casting slab surface quick cooling device and method.
Background
The continuous casting billet hot charging and hot delivering process is adopted to realize the efficient utilization of clean energy contained in the continuous casting billet, so that the energy consumption of a heating furnace can be reduced, the heating time can be shortened, pollutant emission and environmental heat load can be reduced, and the continuous casting billet hot charging and hot delivering process is a main target pursued by green production of each iron and steel enterprise. However, the hot-feed temperature of the cast slab has to be controlled below 550 ℃ due to the presence of the red-feed cracks. In order to fully utilize heat contained in a continuous casting billet, a great deal of basic research work has been carried out by metallurgical workers in recent years, and it has been found that the occurrence of red-feed cracks can be effectively avoided by controlling the temperature of the surface layer of the casting billet within the range of 8-10 mm to below about 670 ℃, i.e., the surface layer obtains a pure ferrite phase. In actual production, the length of a common casting blank can reach 2.5-3 meters at the minimum, the cooling time of the continuous casting blank in a quick cooling box is required to be about 3 minutes, the pulling speed of a continuous casting machine is about 1m/min, and the operation mode of stagnation cooling of the quick cooling box is almost a limiting link for restricting the smooth running of the production process. In order to ensure the smooth operation of the casting machine production, the casting blank must be immediately moved out of the rapid cooling box after the rapid cooling box stops spraying water. This causes the cooling water remaining on the surface of the cast slab to be heated to evaporate the steam into the air, resulting in steam pollution. Especially in winter, it causes great harm to the factory building in frozen areas.
