Japanese Patent JPS54136312
Kind Code:
U
Abstract:
A protective refractory member which protects heat absorptive elements such as pipe in a furnace comprises two parts connected at their respective longitudinal edges to form a peripherally continuous hollow member. Both parts include a reticulated metal structure solidly embedded within a castable refractory matrix. In one of the parts the reticulated metal structure extends outward from each longitudinal edge to form two closed loops. The other part has associated with it a clip connected to the reticulated metal structure. The clip is partially embedded within the part and has hook-like projections, preferably two or more, extending outward from the longitudinal edge which engage the closed loops of the other part to form the hollow protective member. The hook-like connection can also be used to form protective members having discontinuous peripheries.
