The utility model discloses an alignment device for a continuous casting steel ladle with a long water opening in the field of steel continuous casting to solve the problem that the alignment of the upper part of the long water port and the lower water inlet of the ladle is difficult. It consists of the umbrella bone shape of the whole steel, which is composed of a head, a supporting ring and a vertical connecting rod. The umbrella bone is made up of a steel wire connected by the head with at least three heads, the upper end of the vertical connecting rod is connected with the wire head, the lower end of the vertical connecting rod is connected with the center of the ring, and the steel wire is symmetrical distributed under the center syncline with the vertical connecting rod. The supporting ring is a inverted cone shaped conical shape consistent with the taper of the long nozzle bowl, and can be tightly placed in the bowl of the long water inlet. When installing the long water inlet of the ladle, the utility model is placed in the water mouth bowl, and the head is directed upward through the umbrella bone shape, and the long water inlet of the ladle can be accurately aligned and precisely aligned to the lower water inlet of the ladle.

技术介绍
随着用户对钢材质量要求的不断提高,如何减少钢中非金属夹杂物的含量,进而提高钢的洁净度,已经成为炼钢科学技术研究的重点。钢水与空气中的氧接触,导致二次氧化是钢中夹杂物的重要来源。连铸是炼钢生产中的最后一道工序,由于该过程中所产生的二次氧化夹杂难以上浮去除,往往随钢水凝固在铸坯中,其危害最为严重。为避免钢水二次氧化,连铸过程采用各种手段减少钢液与空气的接触。连铸钢包长水口是连铸保护浇铸的一种装置,安装在钢包底部,钢包长水口顶部水口碗与钢包下水口连接,底部出口浸入在中间包熔池的钢液中,用于从钢包向连铸中间包输送钢水。由于钢包长水口位于中间包熔池区上部和钢包下部,温度炙烤下,工人无法靠近,因此,钢包长水口的安装是采用人操作机械手臂,将装有长水口的机械手臂前叉旋转至安装位,将钢包长水口的水口碗对准钢包下水口,操作机械臂向上抬起,将长水口与钢包下水口连接,并顶紧,防止钢包下水口和长水口的水口碗的连接处吸气。目前存在的问题:1、钢包长水口安装时,长水口上部的水口碗与钢包下水口出口对准 ...
