Abstract:
To provide: a monolithic refractory for a slag exhaust portion, materializing reduction of deformation, rupture or falling of the monolithic refractory; and a ladle.SOLUTION: A monolithic refractory 2 for a slag exhaust portion can be installed at a slag exhaust portion 11 of a ladle 1. The monolithic refractory 2 for a slag exhaust portion comprises: a bottom portion 2a installed in the slag exhaust portion 11; an outer wall portion 2b equivalent to an outer circumferential side OUT of the ladle 1; an inner wall portion 2c equivalent to an inner circumferential side IN of the ladle 1; and a top wall portion 2d opposite to the bottom portion 2a. The monolithic refractory 2 for a slag exhaust portion comprises a recessed portion 3 in which, when it is installed in the slag exhaust portion 11, the outer wall portion 2b is recessed to an inner side in a radial direction than a steel shell 12 as an outer shell forming the outer circumference of the ladle 1 in a furnace top portion 10, and a part is recessed to the side of the inner wall portion 2c. When the bottom portion 2a of the monolithic refractory for a slag waste portion 2 is installed in the slag waste portion 11, the height of the furnace top portion 2d is made the height of an upper end portion 10a of the ladle 1. When the ladle 1 comprises a support tool 5 in the furnace top portion 10, a portion of the outer wall portion 2b is contacted with a portion of the support tool 5, and also, a portion of the support tool 5 penetrates into the recessed portion 3.SELECTED DRAWING: Figure 1
