等の問題点がある。2. Description of the Related Art Conventionally, silica board has been used as a coating material for a tundish of a steel type that dislikes inclusions such as alumina and magnesia. For example, Japanese Patent Publication 62-32150
In the publication, limestone in which refractory raw materials are not subjected to calcination treatment,
Disclosed is a refractory heat insulating plate for tundish, which is characterized by adding at least 2 to 20% by weight of dolomite.
However, a fireproof heat insulating plate such as a silica board has problems that the manufacturing cost is high and that it takes time to construct a tundish.

工体の剥離を防止することができる。The silica-based spraying material of the first invention is characterized in that silica glass and natural silica raw material are used together in the aggregate portion. Quartz transforms from α-quartz to β-quartz at 550 to 600 ° C, and exhibits negative expansivity at temperatures above 1300
It transforms to β 2 tridymite and β cristobalite at temperatures above ℃, but the expansion coefficient of quartz glass is extremely small. Here, the spray material using only the natural silica raw material for the aggregate is advantageous in terms of cost because the natural silica raw material is cheaper than quartz glass, but in the temperature range of 550 to 600 ° C. Peeling due to abnormal expansion occurs and cannot be put to practical use. However, by using the natural silica raw material and quartz glass in combination, the absolute value of abnormal expansion can be made small, and thus the peeling of the sprayed construction body can be prevented.
