PURPOSE:To pour refractories automatically, continuously and uniformly over the entire circumference of a vessel for molten metal by using a specific hopper for dropping the coating mateial to be used in lining said vessel onto a circular conical distributing device for molding flasks. CONSTITUTION:The refractory materials for pouring which are kneaded with a mixer 1 are placed on a belt conveyor 2 and are dropped into a hopper 10. The hopper 10 has the function of dropping the coating materials for pouring uniformly over the entire slope from right above the device 5, and the opening part of the dropping port in the lower part thereof is circular. Since the size of the circular shape varies with the kinds, moisture, supply rate, etc. of the refractory materials, the corresponding size is selected by exchanging a socket 12. Further, its height is adequately adjusted to drop the refractory materials onto the device 5 and to pour the same between a ladle 4 and molding flasks 3, whereby the ladle 4 is lined. |
