DEVICE FOR REMOVING SLAG AND METAL RESTS FROM CRUCIBLE OR CASTING LADLES Russian patent published in 1995 - IPC

FIELD: foundry engineering. SUBSTANCE: device has a frame mounted carriage ascendable in sloping direction over guideways or rails. Carriage has cutting mechanism with cutting head. Crucible is mounted on fixing appliance in initial position. When fixing appliance is turned from initial to working position crucible turns coaxial to cutting mechanism. Cutting head diameter is equal to crucible inner diameter. Head has several first cutting members distributed over cutting head periphery and several second radial directed cutting members distributed in front part of cutting head. Allocation of second cutting members enables clear up the bottom part of crucible. Besides cutting head has through holes passing in axial direction and serving for removing slag and metal rests. EFFECT: improved design. 4 cl, 3 dwg
