CHARGING DEVICE FOR SHAFT FURNACES

摘要

A rotatable and angularly adjustable charging and distribution device for shaft furnaces, particularly blast furnaces, is presented. A cylindrical or frustoconical distribution spout is suspended at three points which define a plane. The three points of suspension are caused to move longitudinally (i.e. substantially vertically) and synchronously whereby the lateral surface of the distribution spout will slide over a surface which is virtually conical without rotating the suspension points about the vertical axis of the furnace. The suspension points may be moved either by delivering a driving force to them or by applying a traction force to them.
