Description
技术领域technical field

背景技术Background technique
目前国内大多数连铸机的生产中，为了保证钢的浇注质量，大包→中间包→结晶器装置一般采用大包长水口、中间包塞棒、结晶器浸入式水口三大件进行保护浇注。如果中间包钢水直接采用浸入式水口进入结晶器浇注，则不会发生偏流，但这种浇注方式不仅设备结构复杂，而且成本较高。At present, in the production of most continuous casting machines in China, in order to ensure the pouring quality of steel, the ladle → tundish → crystallizer device generally adopts three major parts: ladle long nozzle, tundish stopper rod, and crystallizer submerged nozzle for protective pouring . If the molten steel in the tundish is poured directly into the mold through the submerged nozzle, no bias flow will occur, but this pouring method is not only complicated in equipment structure, but also high in cost.
而在普钢连铸机上，由于对钢的质量要求不是很严格，目前仍采用的是定径水口浇注，即敞开式浇注，该浇注方式由于没有浸入式水口，不能严格控制从定径水口出来的钢水在结晶器中的落点，若落点不在结晶器中心就会造成偏流，容易发生结晶器漏钢的事故。On the ordinary steel continuous casting machine, because the quality requirements for steel are not very strict, the sizing nozzle pouring is still used at present, that is, the open pouring. Since this pouring method does not have a submerged nozzle, it cannot be strictly controlled from the sizing nozzle. If the drop point of molten steel in the crystallizer is not at the center of the mold, it will cause a bias flow, and accidents of steel breakout in the mold will easily occur.
因此，急需一种确保中间包定径水口在安装施工过程中与连铸结晶器中心对中的装置，以避免在敞开连铸浇注过程中发生偏流。Therefore, there is an urgent need for a device to ensure that the sizing nozzle of the tundish is centered with the center of the continuous casting mold during installation and construction, so as to avoid bias flow during the open continuous casting pouring process.
