摘要
METHOD FOR BOTTING THE TAP HOLE OF A SHAFT FURNACE AND BOTTING MACHINE FOR IMPLEMENTATION OF THIS METHOD A method is provided for botting a tap hole of a shaft furnace using a botting gun fitted with a first hydraulic actuating cylinder holding the botting gun in bearing contact against the wall of the furnace, while a second actuating cylinder actuates a piston which injects the botting mass into the tap hole. In order to limit the contact pressures between the tip of the botting gun and the wall of the furnace, the supply pressure P1 of the first actuating cylinder is modulated as a function of the supply pressure P2 of the second actuating cylinder.
