FIELD: metallurgy. ^ SUBSTANCE: distributor consists of vertical cylinder chamber wherein there are arranged stationary hopper, sleeve with mechanism of rotation and tray with mechanism changing its tilt angle. The mechanism changing tilt angle of the tray has a pusher with a roller mounted on the sleeve, also, the pusher with the roller is made with a slot wherein there is assembled a link of the crank gear connected to a suspension whereon there is suspended the tray by means of journals, and a horizontally mounted cam. The cam is made in form of an eccentric with a circular slot contacting the roller of the pusher; eccentricity of the cam is equal to half of pusher stroke. ^ EFFECT: distributing charge on surface of blast furnace under working modes with automatic control at high accuracy of stop. ^ 3 dwg |
