Zusammenfassung:	PURPOSE:To improve flowability and fillability at the time of flowed-in forming as the lining of a molten metal vessel and to improve durability and corrosion resistance as the lining. CONSTITUTION:In refractories for flowed-in forming based on refractory aggregate such as alumina, spinel or bauxite, spherical refractory aggregate having sphericity of >=0.75 is allowed to account for 10-50wt.% of the total amt. and spherical pitch having sphericity of >=0.75 is incorporated by 1-5wt.%. The pref. diameter of the spherical refractory aggregate is in the range of 0.5-5mm and that of the spherical pitch is in the range of 0.5-2mm.
