Abstract

PURPOSE:To make production of class B coarse aggregate of blast furnace slag possible by flowing the slag slowly while moving a pan carrier gently at the time of flowing the molten slag in the slag pan having an outflow part which is extremely short as compared to the length of the pan to a field. CONSTITUTION:At the time of flowing the molten slag S in a slag pan 2 having an outflow path which is extremely short as compared to the length of the pan 2 to a field 4, the pan 2 is inclined to flow the slag at a right angle to the moving direction of a pan carriage 1 while the carriage 1 is slowly moved on tracks 3. Then, the slag ore having good aggregate characteristics is obtained by this slag flowing method.
