Abstract:Punching tuyere is an important operation in side blown smelting process and there is no mature tuyere puncher equipment for side blown furnace at present. Aiming at the characteristics of side-blown furnace tuyere, an intelligent robot puncher was developed based on AGV technology for the first time. The functions such as automatic navigation positioning, automatic tuyere alignment, intelligent punching and so on were realized. This equipment has been applied in the industrial field successfully and solved the problem of automatic punching tuyere in side blown smelting production.
