When smelting, the metal solution is solidified and is condensed with the dummy ingot head, the ingot pulling rod can keep lifting and rotating, the spindle is continuously pulled out of the crucible, and then the ingot in the crucible is more refined and longer. When the ingot is prepared to be discharged after smelting, the ingot pulling rod can be lowered to the lowest position, the steel wire rope of the winch is lowered, the discharging barrel is enabled to integrally move downwards along the sliding track, and the discharging height is guaranteed to be reached. The spindle pulling device is then moved out together with the spindle by the transport trolley.

5. The travelling bogie positioning device is only provided with a travel switch, and the brake is not sensitive enough;
6. The brake device of the transport trolley is completed by controlling the brake pin through the hydraulic cylinder, has time delay and poor braking effect, greatly influences the accuracy of centering the discharging cylinder and the furnace body flange, and can only slow down the travelling speed and slow down the influence on a medium mode. Greatly increases the operation difficulty of field staff.
