Description
技术领域technical field
本实用新型属于钢铁行业连铸控流保护浇注应用领域，特别是涉及一种简单而高效的连铸控流保护浇注用虹吸水口装置。The utility model belongs to the application field of continuous casting flow control protection pouring in the iron and steel industry, in particular to a simple and efficient continuous casting flow control protection pouring siphon nozzle device.
背景技术Background technique
连铸是把钢液浇铸成固态铸坯的工艺过程，钢液从钢包下部的长水口流入中间包，然后从中间包下游的浸入式水口连续注入水冷结晶器，冷却形成具有一定形状和厚度的坯壳，从结晶器出口连续拉出，经喷水冷却凝固后形成铸坯。20世纪50年代，作为钢铁工业革命标志的钢连铸技术发展起来，与传统模铸技术相比，连铸具有金属回收率高、能量消耗低的优点，全连铸的实现更使炼钢工序简化，生产效率提高。Continuous casting is the process of casting molten steel into a solid billet. The molten steel flows into the tundish from the long nozzle at the lower part of the ladle, and then continuously pours into the water-cooled crystallizer from the submerged nozzle downstream of the tundish, and is cooled to form a tundish with a certain shape and thickness. The slab shell is continuously pulled out from the mold outlet, cooled and solidified by spraying water to form a slab. In the 1950s, the steel continuous casting technology as a symbol of the steel industry revolution was developed. Compared with the traditional die casting technology, continuous casting has the advantages of high metal recovery rate and low energy consumption. The realization of full continuous casting makes the steelmaking process more efficient. Simplify and increase productivity.
连铸过程中，钢液在中间包和结晶器内的流动是一种多相流和不稳定流，同时伴随着大量微细夹杂的运动及钢水的热传递，中间包与结晶器则是通过浸入式水口及塞棒或滑板控流系统连通与阻断。传统的浸入式水口安装在中间包下部，钢液在中间包内靠钢液静压力流入中间包底部出口，经浸入式水口保护浇注，注入结晶器内。目前人们的研究主要集中在浸入式水口的材质、形状、结构、辅助器件与功能等方面的研究，但都局限于安装在中间包下部的方式，即中间包、浸入式水口、结晶器是上、中、下的垂直排列布置。对现有连铸系统设备布置的情况研究发现，上、中、下的布置方式平台高度大，钢液冲击能强，系统能耗高。During the continuous casting process, the flow of molten steel in the tundish and mold is a multiphase flow and unstable flow, accompanied by the movement of a large number of fine inclusions and the heat transfer of molten steel. Type nozzle and stopper rod or slide plate flow control system is connected and blocked. The traditional submerged nozzle is installed at the lower part of the tundish, and the molten steel flows into the bottom outlet of the tundish by the static pressure of the molten steel in the tundish, and is poured into the crystallizer through the submerged nozzle for protection and pouring. At present, people's research mainly focuses on the material, shape, structure, auxiliary devices and functions of the submerged nozzle, but they are all limited to the way of installing the lower part of the tundish, that is, the tundish, submerged nozzle, and crystallizer are the upper part. , middle and lower vertical arrangement. According to the research on the equipment layout of the existing continuous casting system, it is found that the upper, middle and lower layout has a large platform height, strong impact energy of molten steel, and high energy consumption of the system.
传统连铸控流保护浇注过程中，中间包水口处有漩涡汇流，浸入式水口内钢液流速高，冲击大，使结晶器内钢液流场复杂。In the pouring process of traditional continuous casting flow control protection, there is a vortex confluence at the nozzle of the tundish, and the flow rate of molten steel in the submerged nozzle is high and the impact is large, which makes the flow field of molten steel in the mold complex.

用虹吸水口控流保护浇注的方法是：将虹吸水口管道横跨中间包5壁，上升管6插入80t中间包5，下降管8插入200×1600mm矩形坯结晶器10，调整并固定好虹吸水口位置，控流滑板9保持关闭；待中间包钢液5上升至距包底850mm后，打开抽吸装置阀门3，抽吸管道内的气体，中间包钢液4自上升管6经水平斜管7流入下降管8后，打开控流滑板9开口度为100%，关闭抽吸装置阀门3，钢液注入结晶器10内，完成开浇；保护浇注过程中根据结晶器钢液11液面和中间包钢液4液面情况，调整控流滑板9开口度在80~95%进行控流操作；保护浇注过程中，若虹吸水口因夹杂物结瘤堵塞水口，可并列插入一根新的虹吸水口，快速替换下旧的虹吸水口；停浇时，关闭控流滑板9停止浇注。The method of using the siphon nozzle to control the flow and protect the pouring is as follows: the siphon nozzle pipe spans the wall of the tundish 5, the ascending pipe 6 is inserted into the 80t tundish 5, the descending pipe 8 is inserted into the 200×1600mm rectangular billet crystallizer 10, and the siphon nozzle is adjusted and fixed. position, the flow control slide 9 remains closed; when the tundish molten steel 5 rises to 850mm from the bottom of the tundish, the valve 3 of the suction device is opened to suck the gas in the pipeline, and the tundish molten steel 4 passes through the horizontal inclined pipe from the ascending pipe 6 After the 7 flows into the downcomer 8, the opening of the flow control slide plate 9 is opened to 100%, the valve 3 of the suction device is closed, and the molten steel is injected into the crystallizer 10 to complete the pouring; For the liquid level of molten steel 4 in the tundish, adjust the opening of the flow control slide plate 9 at 80-95% for flow control operation; during the protection pouring process, if the siphon nozzle is blocked by inclusions, a new siphon can be inserted in parallel Nozzle, quickly replace the old siphon nozzle; when stopping pouring, close the flow control slide 9 to stop pouring.
