Background
In the production process of the continuous casting process of ferrous metallurgy, molten steel needs to be subjected to spray cooling after being continuously cooled from a liquid state to a solid state, and the spray cooling efficiency is high or low, and whether the cooling is uniform or not has very important influence on the quality of a billet. The quality of the working state of an atomizing nozzle serving as a core component for spray cooling has important influence on the cooling of a casting blank, and the most basic requirements of the nozzle on the non-leakage, non-blockage and rapid removal of blockage of the nozzle of a continuous casting machine are. Generally speaking, in normal production of a continuous casting machine, the nozzle cannot have the conditions of steam leakage, nozzle steam blockage, breathing spray, bifurcation spray, angle reduction and the like, the online perfectness rate of the nozzle for producing general steel types must be kept above 95%, when producing some steels with strong crack sensitivity, such as peritectic steel, microalloy steel, high-carbon steel and the like, the requirement on the nozzle perfectness is more strict, the online perfectness rate of the nozzle must be ensured to be above 98%, otherwise, the surface and internal quality of a casting blank will be obviously reduced, the qualification rate of the casting blank is influenced, on the other hand, the abnormal rate of the nozzle is high, the pulling speed of the casting machine is reduced, even the continuous casting machine needs to be stopped for maintenance and nozzle replacement, which has great influence on the operation rate of the continuous casting machine, therefore, from the quality and constant of the continuous casting machine, the perfectness rate of the online nozzle must be ensured to be above 95%, this has a very important influence on the production of continuous casting machines.
At present, during the production of a continuous casting machine in the ferrous metallurgy process, the secondary cooling nozzles used are mostly simple double-medium internal mixed gas-water atomizing nozzles or single-medium full-water nozzles, the nozzles have many defects in design, the nozzles are simple and crude in the design of a water-gas inlet, only the requirements of the water-gas amount of the nozzles are combined, a single water-gas path is established, the diameters of the water-gas paths are only about 1-4mm, the nozzles can be blocked as long as particles with similar diameters are sprayed, the water quality of a steel mill at present is generally poor, the large particle content in water is high, the nozzle blockage cannot be avoided, the blockage rate of a casting secondary nozzle on a new nozzle of the steel mill is over 40 percent, and the pulling speed and the casting blank quality are seriously influenced. Thirdly, when the existing nozzle is used for treating particles and oil sludge blockage, the nozzle must be completely dismantled to be decomposed and cleaned of foreign matters, which undoubtedly increases the working difficulty and workload, and the existing nozzle is single and simple in design, so that the nozzle has poor sealing stability at high temperature, low blockage prevention capability of the online nozzle and low online pollution discharge measure efficiency, and the operation cost of the nozzle is extremely high. The quality and yield of the casting blank are greatly influenced.
