Problems solved by technology

However, after many tests, it was found that the casting is easy to crack and the pass rate is low, so it is difficult to promote it in practice.
For the assembly of phosphorus pig iron, the temperature of phosphorus pig iron is as high as 1320°C during the casting process, while the temperature of carbon blocks and steel rods is relatively low, which makes the carbon blocks crack, which affects the normal use of carbon blocks
The cracking of the carbon block increases the production cost of electrolytic aluminum and reduces the service life of the electrolytic cell

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] Such as Figure 1-Figure 4 As shown, the phosphorus pig iron casting unit of the present invention is composed of a mobile vehicle 1, a ladle system 2, a gantry system 3, a lifting mechanism 4, a gate distribution system 5, a control cabinet 6, a heating cover 7, a hydraulic station 8, and a rail 9. It is composed of cathode steel rod 10, cathode carbon block 11, workbench 12 and other components.

[0023] All the power of the whole system is provided by the hydraulic station 8. Four cathode carbon blocks 11 are placed in one heating mantle 7, and one cathode carbon block 11 requires four cathode steel rods 10 to assemble, and each cathode steel rod 10 corresponds to a gate.

[0024] The gate splitting system 5 has four groups, and each group has four gates, which just correspond to the cathode steel bars 10 . The gate splitting syst...

Abstract

The invention discloses an aluminum electrolysis cathode carbon block phosphorous pig iron casting unit and method. The unit is provided with a movable trolley (1), the movable trolley (1) moves along a track (9) and is provided with a portal system (3), a transverse frame of the portal system (3) is provided with a lifting mechanism (4), a sprue separation system (5) is arranged below the transverse frame of the portal system (3), one side face of the portal system (3) is provided with a casting ladle system (2), and the other side face of the portal system (3) is provided with a control cabinet (6). All power of the whole system is supplied by a hydraulic station (8). The full-hydraulic system is adopted, the power cost is reduced, meanwhile, ordinary start and stop of the movable trolley are more stable, and the service life is prolonged. The aluminum electrolysis cathode carbon block phosphorous pig iron casting unit is driven by a pair of oil cylinders, and lifting control over a heating cover, the sprue separation system and a finished product cathode carbon block set is achieved. Takt type automatic casting is achieved in a station mode of 6+1.

Description

technical field [0001] The invention belongs to the technical field of aluminum electrolytic cells, and in particular relates to an aluminum electrolysis cathode carbon block phosphorus pig iron casting unit and a casting method. Background technique [0002] Cathode carbon block assembly is a process of closely combining the cathode carbon block and the cathode steel rod. There are three main methods for the assembly of cathode carbon blocks: the carbon paste tamping assembly method is to fill the gaps on both sides of the steel rod with carbon paste, and then use pneumatic tools to tamp and compact it; the phosphorus pig iron casting method is to use melted phosphorus pig iron The method of casting the gap between them and making them integrated after condensation; the bonding method is a method of bonding the cathode carbon block and the steel rod together with a binder or carbon glue. At present, the carbon paste tampering assembly method is widely used in China, and th...
