摘要： An inorganic fiber-formed article, composed of a mat-shaped inorganic fiber assembly, the inorganic fiber-formed article including needle marks that extend in a direction including a thickness direction of the mat-shaped inorganic fiber assembly, where the needle marks include needle marks A and needle marks B having a diameter smaller than that of the needle marks A, dense portions in which a plurality of the needle marks A lie densely are arranged apart, non-dense portions in which a needle mark density of the needle marks A is lower than that in the dense portions are present between the dense portions in both a first direction which is any mat-surface direction extending through the dense portions and a second direction orthogonal to the first direction, and the needle marks B are present at least in the non-dense portions.

摘要： A heat-insulating protective member for skid posts contains a needled blanket of inorganic fibers. At least some of the needled blanket has, disposed therein, an impregnation part where an oxide-precursor-containing liquid is adherent in an undried state. The impregnation part has a water content of 50-400 parts by mass per 100 parts by mass of the inorganic fibers of the impregnation part. The water content of the heat-insulating protective member is 50-400 parts by mass per 100 parts by mass of the inorganic fibers of the heat-insulating protective member. The oxide-precursor-containing liquid contains ingredients that, upon burning, yield a composition containing Al2O3 and CaO. The oxide-precursor-containing liquid is adherent in an amount of 2-50 parts by mass in terms of oxide amount per 100 parts by mass of the inorganic fibers of the impregnation part. A molar ratio of Al/Ca, in the whole impregnation part is 10-330.
