Fifth , the furnace structure description:
5.1 mechanical principles described structure
The furnace body adopts a steel shell yoke furnace body, and the outlet channel "gate" of the metal melt is arranged at the bottom of the electric furnace. ( High-aluminum graphite or zirconia nozzle ) Since the metal is in the smelting process, impurities and slag float on the liquid surface; the bottom-injection casting can prevent impurities and slag from entering the casting cavity, greatly reducing the occurrence of waste. The steel water outlet is connected with a plug rod action mechanism; the plug rod action mechanism comprises a plug rod, a cylinder and a transmission lever, the bottom shape of the plug rod is adapted to the shape of the molten steel outlet, and the bottom of the plug rod is tapered from top to bottom; the cylinder drive transmission The lever rotates along a fixed axis, and the transmission lever drives the plug to raise or lower. Use the rising or falling movement of the plug rod action mechanism to control the opening, closing or opening of the taphole, and precisely control the tapping point and tapping flow rate and the tapping flow rate.
The plug rod action mechanism comprises a stopper rod 2, a cylinder 3 and a transmission lever 4, the cylinder 3 is connected to one end of the transmission lever 4, and the bottom of the cylinder is fixed ; the stopper rod 2 isconnected to the other end of the transmission lever 4, the bottom shape of the stopper rod 2 and the molten steel outlet The shape is adapted, and the bottom of the stopper rod 2 is tapered from top to bottom; the cylinder 3 drives the transmission lever 4 to rotate along a fixed axis, and the transmission lever 4 drives the stopper rod 2 to ascend or descend. It is characterized in that the steel water outlet has a circular cross section, and the bottom of the stopper rod 2 has a circular cone shape. The other end of the transmission lever 4 is fixedly connected with a suspension sleeve 5 for suspending the stopper rod 2 from the transmission lever 4. The stopper action mechanism further includes a rotary bearing 6 that connects between the suspension sleeve 5 and the stopper rod 2. The plug action mechanism further includes a bracket 7 to which the sleeve type adjuster (8) is fixedly coupled; a buffer spring 10 and a position fixing rod 9 are further fixed, and the lower end of the suspension sleeve 5 is fixed to the upper end of the buffer spring 10 The lower end of the buffer spring (10) is fixed to the inner ring of the rotary bearing (6), and the outer ring of the rotary bearing 6 is connected to the position fixing rod (9)
