Abstract
The invention concerns a method for cooling a shaft furnace loading device, said loading device being equipped with a ring-shaped rotary joint ( ), provided with a fixed ring-shaped part ( ) and a rotating ring-shaped part ( ), for supplying cooling liquid to a rotating cooling circuit ( ). The invention is characterized in that it consists in feeding the joint ( ) fixed part ( ) with cooling liquid such that a leakage flow passes in a separating ring-shaped slot ( ) between the fixed part ( ) and the rotating part ( ) of the joint ( ), to form therein a liquid joint. Said leakage flow is then collected and drained without passing through the cooling circuit ( ).
