Molten metal ladle

Abstract

An object of the present invention is to provide a molten metal ladle in which scales, slag, etc., that adhere to the lining surface can be removed easily and reliably. The present invention provides a molten metal ladle provided with a bottomed tubular ladle body having an opening on the top, wherein the ladle body ( 10 ) has an upper ladle portion ( 12 ) and a lower ladle portion ( 11 ); the upper ladle portion ( 12 ) being connected to the top end of the lower ladle portion ( 11 ); lining layers ( 17,18 ) being provided inside the upper ladle portion ( 12 ) and lower ladle portion ( 11 ); and the innermost surface of the lining layer ( 18 ) of the upper ladle portion ( 12 ) being formed as an inclined plane wherein the opening area decreases from the top of the lining layer ( 17 ) of the lower ladle portion ( 11 ) toward the edge of the opening ( 13 ).

1 . A molten metal ladle comprising a bottomed tubular ladle body and an opening in an upper portion thereof;
 the ladle body being provided with an upper ladle portion and a lower ladle portion;   the upper ladle portion being connected to the top end of the lower ladle portion;   the upper ladle portion and the lower ladle portion each being provided with a lining layer inside thereof;   the innermost surface of the lining layer of the upper ladle portion being formed as an inclined plane having an opening area decreasing from the top end of the lining layer of the lower ladle portion to the edge of the opening.   
   
   
       2 . A molten metal ladle according to  claim 1 , wherein the inclined plane has a fixed inclination angle, as seen in a longitudinal sectional view, from the top end of the lining layer of the lower ladle portion to the edge of the opening. 
   
   
       3 . A molten metal ladle according to  claim 1  or  2 , wherein the lining layer is formed of a heat-insulating member and a refractory member.
