摘要： There are provided a shaft (4) adapted for introduction into a tubular member (6) made of refractory material and an expander provided on a leading edge of the shaft. The expander (3) has both ends provided with a repairing material container (4) and a seat plate (5). With the repairing material container having monolithic refractory material loaded therein confronted to a damaged portion in an inner wall of the tubular member, the expander is expanded by a driving motor (1) to push the repairing material container toward the damaged portion while pushing the seat plate in contact with a wall surface opposite to the damaged portion in behind. Thus, the monolithic refractory material is filled and deposited in the damaged portion under remote control.

摘要： A spray method for monolithic refractories, which comprises feeding, with an air stream, a monolithic refractory composition including a rapid setting agent in addition to refractory aggregates, a refractory powder, a binder and a dispersant in a powder state in a transporting pipe (3) so that the composition is transported in a floating state; adding application water (4) on the way of the transporting pipe; continuing the feeding of the air stream, and spraying the wet composition through a spray nozzle (5). In a case that the monolithic refractory composition does not include the rapid setting agent, the rapid setting agent is added at an upstream side (12) of the top end of the spray nozzle (5), and then, the wet refractory composition is sprayed through the spray nozzle. The spray method eliminates problems in conventional dry spray method or wet spray method; dispenses with the mixing work for the refractory composition; permits a long distance transportation of the refractory composition for a spray operation without causing the blocking of the transporting pipe, and provides sprayed refractories of high quality.
