摘要： PURPOSE: The title lightweight, long-life bucket effective in reducing power cost, which is obtd. by lining with a refractory excellent in thermal impulse resistance, wear resistance and heat resistance, and having a compsn. of a specified wt. ratio of SiC, SiO
2 and Al
2 O
3 .
CONSTITUTION: A refractory having a compsn. of 83W92wt% SiC, 5W12wt% SiO
2 and 0.1W3.5wt% Al
2 O
3 is provided. The inside of the shell 1 of a bucket for a dry coke quenching installation is entirely lined with the refractory 2. Thus the performance of the refractory 1 will not be lowered even if the refractory 2 is exposed to high temp. because the surface of the refractory 2 in contact with the atmosphere forms a glass film of SiO
2 . The obtd. bucket is reduced in wt. to about 1/6 and largely prolonged in life in comparison with a conventional bucket lined with cast steel.

摘要： PROBLEM TO BE SOLVED: To provide a method for preventing breakage and float-up of a block from being caused in a comparatively simple structure by using monolithic refractory as a pre-cast block which is easily dried and a method for manufacturing the pre-cast block used for the same.
SOLUTION: This refractory constructing structure for RH-degassing vessel bottom, is provided with refractory blocks constituting a center block 2 held between two circulating-flow tubes 1, circulating-flow tube tuyeres 3 surrounding the circumference of respective circulating-flow tubes and the other bed parts 6, and the monolithic refractories filled up the gaps and/or the surrounds of these refractory blocks, and the refractory block constituting the central block held between two circulating-flow tubes, has a widening downward reverse jack structure. The vessel bottom central part is lower by ≥30 mm than the circumference and a gap with the block is filled up with the dry-type monolithic refractory. The block is manufactured by partitioning the inner part of a large molding flask with plates.
