摘要： PROBLEM TO BE SOLVED: To reduce Al 2 O 3 base inclusion in molten steel, to restrain mechanical spalling of a refractory and to easily use the hot-rotation in a tundish used for continuously casting a metal especially, a steel. SOLUTION: Since an increase in wearing with the mechanical spalling of the refractory in the case of using MgO-CaO base refractory as the refractory for tundish has a deep dependence with a load softening characteristic of the refractory, when the refractory is held to 5 hours under condition of 0.2 MPa compression stress at 1550°C near the average using temperature of the tundish, the refractory shrunk at 1-10% in the loaded direction is applied to a lining material of the tundish and/or a weir and thus, the stress caused by thermal expansion is absorbed and the occurrence of the mechanical spalling can remarkably be restrained.

摘要： PROBLEM TO BE SOLVED: To improve the quality of a slab by reducing the amount of large alumina inclusions in an aluminum killed steel slab.
SOLUTION: A refractory containing CaO content of 20 mass % or more is applied for 50% or more of the inner hole total area of the divided nozzles comprising an upper nozzle, a sliding nozzle, a lower nozzle, and an immersion nozzle or the like, which allows the alumina in molten steel to be absorbed. Suppressing the alumina from sticking on the inner hole prevents coalescence of alumina to suppress the large alumina inclusions from intruding in the slab.
