发明名称 Method and apparatus for leveling a refractory bed surface
摘要 A leveling apparatus for leveling a surface of refractory bed comprised of refractory pebbles. The leveling apparatus is comprised of a disk having a level bottom surface suitable for positioning upon the surface of the refractory bed. A plurality of spaced apart, downwardly extending tooth members project beneath the level, bottom surface of the disk, and into the refractory bed. Rotation of the disk causes the plurality of tooth members to displace the refractory pebbles in a rake-like manner to thereby level the surface of the refractory bed by causing the refractory pebbles to conform to the level bottom surface of the disk.
