VIBRATING GRIZZLY FOR SLAG PROCESSING

摘要

PROBLEM TO BE SOLVED: To provide a vibrating grizzly for slag processing configured to considerably improve use life than conventional ones.SOLUTION: A vibrating grizzly for slag processing includes grizzly bars 5 that are welded at predetermined intervals on the upper side of each of a plurality of support pipes 4. A welding-defect progress preventing member 10 made of a material having superior weldability to the material of the support pipes 4 is welded to the upper surface of each of the support pipes 4, and the grizzly bars 5 are welded to the upper surface of the welding-defect progress preventing member 10. The welding-defect progress preventing member 10 is preferably a steel plate having a thickness of 6-12 mm. This prevents a fatigue crack from being formed in the support pipes 4.
