Embodiment 1）
[0217] As shown in Table 1, the solid content of the following refractory shaped body forming materials was weighed and filled into a kneader: 30.0 parts by mass of high-alumina cement as a binder; 40.0 parts by mass of silica as inorganic particles, 30.0 parts by mass of wollastonite particles; 2.2 parts by mass of acrylonitrile-butadiene copolymer latex-coated glass as a bundle-shaped inorganic fiber aggregate whose surface is covered with a resin having a glass transition temperature of 40°C or less Fiber chopped strands (on the surface of a bundle-shaped glass fiber aggregate with a diameter of 1 mm and a length of 10 mm obtained by cutting neatly concentrated glass continuous fibers, covering 10 parts by mass with respect to 100 parts by mass of the bundle-shaped glass fiber aggregate Part glass transition temperature of -31 ℃ acrylonitrile - butadiene copolymer latex resin made of glass fiber chopped strands). Next, to the above-mentioned kneader, 15 parts by mass of wat...
Embodiment 2～ Embodiment 7）
[0223]As shown in Table 1, except that the blending ratio of cement, inorganic particles, and a bundle-shaped inorganic fiber aggregate formed by covering the surface with a resin having a glass transition temperature of 40° C. or lower was changed, the same operation was carried out as in Example 1, A ladle with support members is produced. In each of the obtained ladles, voids such as pores and voids were not observed. Table 2 shows the composition of the refractory molded body constituting the obtained ladle.
[0224] In addition, the Tap flow value was measured in the same manner as in Example 1 using the kneaded products obtained in each Example. The results are shown in Table 1. Then, using the above-mentioned kneaded product, a rectangular prism-shaped molded product was produced in the same manner as in Example 1, and the bulk density and Charpy impact value of each molded product were measured in the same manner as in Example 1. The results are shown in Table 2. V...
Embodiment 8～ Embodiment 9）
[0243] As shown in Table 5, in addition to being a bundle-shaped inorganic fiber aggregate formed by covering the surface with a resin with a glass transition temperature of 40°C or less, the silica fiber chopped strands were coated with acrylonitrile-butadiene copolymer latex. Silk (on the surface of a 1 mm diameter, 10 mm long bundle-shaped silica fiber aggregate obtained by cutting neatly concentrated silica continuous fibers, relative to 100 parts by mass of the bundle-shaped silica fiber aggregate, Silica fiber chopped strands formed by covering 10 parts by mass of acrylonitrile-butadiene copolymer latex with a glass transition temperature of -31°C) to replace acrylonitrile-butadiene copolymer latex coated glass fiber short The strands were cut, and as shown in Table 5, the blending ratio of cement, inorganic particles, and a bundle-shaped inorganic fiber aggregate formed by covering the surface with a resin with a glass transition temperature of 40° C. or less was changed...
