Abstract

A monolithic refractory structure includes: a monolithic refractory; a support body which supports the monolithic refractory; and a heat-resistant fiber support material which is buried in the monolithic refractory in a state of being connected to a support surface of the support body. The heat-resistant fiber support material includes a heat-resistant fiber rope which is formed of an inorganic fiber and extends along an X-axis direction perpendicular to the support surface, and a ratio L1/L2 of an X-axis direction length L1 of the heat-resistant fiber rope to an X-axis direction length L2 of the monolithic refractory is 0.35 or more and 0.95 or less.

First claim

The invention claimed is:

1. A monolithic refractory structure comprising:
a monolithic refractory;
a support body which supports the monolithic refractory; and
a heat-resistant fiber support material which is buried in the monolithic refractory in a state of being connected to a support surface of the support body,
wherein the heat-resistant fiber support material includes a heat-resistant fiber rope which is formed of an inorganic fiber and extends along an X-axis direction perpendicular to the support surface,
a ratio L1/L2 of an X-axis direction length L1 of the heat-resistant fiber rope to an X-axis direction length L2 of the monolithic refractory is 0.35 or more and 0.95 or less,
the heat-resistant fiber rope includes one or more annular portions,
the heat-resistant fiber rope is hardened by a hardener, the hardener being oil varnish, coal-tar pitch, phosphoric acid, phosphate, silicate, silica sol, or alumina sol,
the heat-resistant fiber support material further includes a connection member which connects the heat-resistant fiber rope to the support body,
the connection member is fixed to the support surface of the support body,
the connection member is a metal ring having a hollow tube shape,
the heat-resistant fiber rope is inserted into and fixed to the metal ring, and
a direction in which a load of the monolithic refractory is exerted on the heat-resistant fiber rope and a direction in which the heat-resistant fiber rope is pulled from the metal ring are different from each other.

2. The monolithic refractory structure according to claim 1 ,
wherein the heat-resistant fiber rope is formed of an inorganic fiber made of a material containing one type or two or more types of Al 2 O 3 , SiO 2 , Al 2 O 3 —SiO 2 , and Al 2 O 3 —SiO 2 —B 2 O 3 .

3. The monolithic refractory structure according to claim 1 ,
wherein the heat-resistant fiber rope includes one or two or more knots.

4. The monolithic refractory structure according to claim 1 ,
wherein the monolithic refractory is divided into a plurality of layers along the X-axis direction, and
the heat-resistant fiber rope has a single annular portion for each of the layers of the monolithic refractory.

5. The monolithic refractory structure according to claim 1 ,
wherein the heat-resistant fiber rope is formed of an inorganic fiber made of a material containing one or more types of SiO 2 , Al 2 O 3 —SiO 2 , or Al 2 O 3 —SiO 2 —B 2 O 3 .
