To provide a refractory for a tuyere containing carbon to prevent wear due to oxygen cleaning.

A refractory 3 for a tuyere of a molten steel container is obtained by the flowed-in forming of the mixture having the composition consisting of, by weight, 100% refractory aggregate which is mainly composed of 80-90% alumina of <10mm in grain size and 3-20% magnesia of ≤75μm in grain size, 1-10% hydraulic alumina, 0.05-5% amorphous silica supper-fine powder, and 1-7% metallic fiber, which are applied to 100% the refractory aggregate.
