First EAF Gunning Manipulator

Velco’s first gunning manipulator for EAF was supplied in 1995 to company Feng Hsin in Taiwan. The telescopic gunning head is moved via a hydraulic cylinder. When the furnace cover is open, the gunning head is lowered into the furnace from the top. The entire furnace can be gunned with the rotating gunning lance. This effects a faster and safer gunning repair.
