To improve the productivity of refractory brick in a method for producing refractory brick having a laminated structure and a continuous slip casting apparatus used in the method and a manufacturing yield by suppressing cracking and defective joining on an extension plane.
In the method for producing the refractory brick in which the refractory brick having the laminated structure in which at least two kinds of refractory layers different in at least one of porosity and composition are laminated is produced by supplying different kinds of slurry-like refractory raw materials for forming the different kinds of refractory layers in turn into a form and slip-casting, when the kind of the refractory raw material supplied into the form is changed over from one refractory raw material to another refractory raw material, after mixed slurry comprising one refractory raw material and another refractory raw material is supplied to form a cushioning layer, the supply of another refractory raw material is started, and another refractory raw material is supplied onto the cushioning layer so that the variation of the thickness of the layer of the refractory raw material supplied already into the form when the supply of another refractory raw material is started is within a prescribed range.
