Description
一种塞棒水口快换装置 技术领域 Plug rod nozzle quick change device
[0001] 本实用新型涉及炼钢设备配件， 是一种塞棒水口快换装置。 [0001] The utility model relates to a steelmaking equipment accessory, which is a quick-change device for a stopper rod nozzle.
背景技术 Background technique
[0002] 钢企炼钢的连铸生产中需要使用水口快换装置， 而目前已有的快换装置均采用 上水口与座砖配合使用的结构， 这种结构的快换装置的不足是： 由于座砖与上 水口配合使用， 座砖与上水口同吋更换， 所以当座砖被浸蚀后， 必须及吋更换 上水口， 否则钢水随吋有被污染的可能， 特别是对于优质钢、 品种钢的产品要 求高洁净生产环境， 从而避免出现产品质量不合格的现象。 而座砖的使用寿命 较短， 当座砖被浸蚀后， 上水口尚未产生被浸蚀的情况下， 仍需同吋更换上水 口， 造成上水口的大量浪费。 另外， 由于座砖的定位面质量较低， 与上水口配 合的定位精度低， 生产安全性低等。 [0002] In the continuous casting production of steelmaking steel, it is necessary to use a nozzle quick-change device, and the existing quick-change devices all adopt the structure in which the water inlet and the seat brick are used together, and the shortcomings of the quick-change device of this structure are: Since the seat brick is used in conjunction with the water inlet, the seat brick and the water inlet are replaced at the same time. Therefore, when the brick is etched, the water inlet must be replaced. Otherwise, the molten steel may be contaminated, especially for high quality steel and varieties. Steel products require a high clean production environment to avoid unqualified product quality. The life of the brick is shorter. When the brick is etched and the water inlet has not been eroded, it is still necessary to replace the water inlet with the same water, resulting in a large waste of the water inlet. In addition, due to the low quality of the positioning surface of the brick, the positioning accuracy associated with the water inlet is low, and the production safety is low.
