Description
技术领域 technical field
本实用新型涉及板坯连铸技术领域，具体地说是一种能控制氩气流量的塞棒。 The utility model relates to the technical field of slab continuous casting, in particular to a stopper rod capable of controlling the flow rate of argon gas.
背景技术 Background technique
连铸已成为现代化钢铁企业炼钢生产的主要方式。塞棒是控制连铸中间包到连铸结晶器的钢水流量和结晶器液面高度的重要元件，通过吹入氩气把水口内壁沉积的固体杂质生成物冲走，并吸附水口内钢水中中的固体杂质生成物，提高钢水的质量。目前通用的塞棒包括一塞棒体及设置在塞棒体底部的塞棒头，在塞棒体的内部开设有氩气通道，塞棒头上开设有导气孔，导气孔与氩气通道在同一轴线上。实际使用时，氩气通道中吹入的氩气通过导气孔以气泡的形态从塞棒头的底部吹出。但是这种塞棒并不能很好的控制氩气的流量，从而造成塞棒无法精确控制钢水流速，造成钢水在水口内有涡流，涡流的不稳定状态影响连铸的整体效率和钢水质量。 Continuous casting has become the main way of steelmaking production in modern iron and steel enterprises. The stopper rod is an important element to control the flow of molten steel from the continuous casting tundish to the continuous casting mold and the liquid level of the mold. By blowing argon gas, the solid impurity products deposited on the inner wall of the nozzle are washed away, and the middle of the molten steel in the nozzle is absorbed. Solid impurity products, improve the quality of molten steel. The current general stopper rod includes a stopper body and a stopper head arranged at the bottom of the stopper body, an argon gas channel is opened inside the stopper rod body, and an air guide hole is opened on the stopper rod head, and the air guide hole and the argon gas channel are connected to each other. on the same axis. In actual use, the argon gas blown into the argon gas channel is blown out from the bottom of the stopper tip in the form of bubbles through the air guide hole. But this kind of stopper can't control the flow of argon gas very well, so that the stopper can't control the flow rate of molten steel accurately, causing the molten steel to have eddy current in the nozzle, and the unstable state of the eddy current affects the overall efficiency of continuous casting and the quality of molten steel.
