Open structure ladle lid device

The utility model relates to a there is open structure's ladle lid, belongs to ladle lid equipment technical field for the refractory material of ladle protection ladle lid when the deslagging is covered in the area. Technical scheme is: open structure's ladle lid is constituteed including steel construction frame, lug, couple, be built by contract casing, refractory material. The steel construction frame welds together with the ladle shell, and ladle shell interior refractory material fills, and open structure's design position is in the reverse position of couple, and it is articulated with the ladle that the ladle lid passes through the couple, and in the stage of normal operating, the coincidence is followed together with the ladle to the ladle lid, when carrying out the deslagging operation, ladle lid and ladle along the angle that produces one 0 -60, when liquid slag flowed, because the ladle is stamped open structure, the slag will obviously reduce erodeing of ladle lid, and the life of ladle lid is greatly improved.
