The invention relates to a series mold bag retrusive type subsection slip
casting device and slip
casting method. The series mold bag retrusive type subsection slip
casting device comprises a series mold bag device, a retrusive type slip casting
pipe and the like; the series mold bag device is composed of three different-length mold bag slip casting steel pipes outside galvanized steel sleeves, an upper mold bag, a middle mold bag and a lower mold bag;
slurry outlet holes are distributed in non-mold-bag zones of the galvanized steel sleeves, the mold bag slip casting steel pipes are bundled to the galvanized steel sleeves through iron wires, each slip casting steel
pipe corresponds to one corresponding mold bag, the mold bags include the upper mold bag, the middle mold bag and the lower mold bag, and the mold bags are bundled to the galvanized steel sleeves through iron wires; and the retrusive type slip casting
pipe is composed of a slip casting pipe, a
slurry stopping plug and the like. The invention further discloses a using method of the device. According to the characteristics of retrusive type subsection slip casting, after the mold bags are supported through slip casting, a stratum is naturally divided into three slip casting sections, and conditions are provided for retrusive type subsection slip casting
slurry diffusion; and meanwhile, the stratum is extruded in the mold bag supporting process, and subsection slip casting is facilitated.
