摘要： PROBLEM TO BE SOLVED: To provide a brick for a tilting barrel of a blast furnace, excellent in abrasion resistance and melting loss resistance to FeO, and also to provide a lining mechanism for a tilting trough of a blast furnace and a tilting trough of a blast furnace having excellent prevention means to injuries. SOLUTION: The brick for a tilting trough of a blast furnace is magnesia-chromium-based fired brick comprising the amount of MgO and Cr 2 O 3 in the brick of at least 80 mass%, the total amount of flux components of Fe 2 O 3 , Al 2 O 3 , SiO 2 and CaO of at most 20 mass% and inevitable impurities in balance. The size of the brick is not lower than 230×114×65 mm and the whole barrel is constituted of at least one block. Optionally, the lining structure is constituted of the compound of the brick and a monolithic refractory. The tilting trough is installed at a shoulder part of the side for receiving pig iron.

摘要： PROBLEM TO BE SOLVED: To provide a molten iron trough for blast furnace with which the erosion and the wear with the molten iron stream are prevented and the durability is improved by preventing the development of crack and the fall-down, etc., with a thermal-spalling action and further, since the erosion and the wear are prevented at the desiliconizing operation, the FeO resistance and the oxidizing resistance are improved and thus, the stable operation for long time can be obtained.
SOLUTION: The molten iron trough for blast furnace is built up as the followings, with which at a part of the inner lining, precast blocks (alumina-spinel quality precast blocks 12a, 12b) are disposed and the precast blocks are lined at least at two or more layers and the back face side of the precast blocks is integrally lined with monolithic refractory (Alumina-SiC-C quality monolithic refractory 11) and the ratio "Lmax/Lmin" of the maximum size (Lmax) and the minimum size (Lmin) in respective directional sizes of vertical size, horizontal size, height of the above block is made to ≤5.
