| 摘要 |
A method of filling cavities in refractory bodies, comprising lofting refractory fibers in flowing air, mixing lofted refractory fibers with refractory foam to generate a fibrous refractory foam, and filling a substantially enclosed cavity in a refractory material with fibrous refractory foam to produce a foam-filled cavity, heating the foam-filled cavity to a first drying temperature for sufficient time to dry the fibrous refractory foam filling, and heating the foam-filled cavity to a second substantially higher firing temperature to produce a fired body. The substantially enclosed cavity is defined by at least one refractory wall.
