Equipment inspection before aluminum ingot production
Aluminum outlet: mainly check whether there is aluminum slag clogged, if there is, clear it.
Outside line rangefinder: Infrared rangefinder is a device on the mixing furnace, used to measure the height of the liquid level in the launder. Before production, carefully check whether its work is normal and whether the cooling air is turned on.
Buoy limit: It belongs to the equipment on the mixing furnace and is also used to control the safety limit of the molten aluminum level. There are high limit, ultra high limit, middle limit, low limit and ultra low limit. If the molten aluminum reaches the super-high limit, the mixing furnace will automatically drop quickly.
Casting launder: Check for damage and breakage, and repair the damage.
Boat-shaped pouring ladle: Turn on and check whether the flow trough rises and falls normally and whether the flow trough is damaged.
Distributor: Check whether the screws of the distributor are tight and whether the vertical and horizontal positions of the distributor are adjusted properly.
Casting machine: starting up and running, whether the casting machine is normal, check whether the mold and chain plate screws are tight, whether each part is lubricated, and whether each limit is working properly.
Cold transport machine: When starting up and running, whether the cold transport machine is normal, check whether the chain plate screws are fastened, whether each part is lubricated, and whether each limit is working properly.
Stacker: When the stacker is started up and running, whether the stacker is normal, check whether each base bolt is fastened, whether each part is lubricated, and whether each limit is working properly.
Equipment maintenance before aluminum ingot production
The following equipment maintenance work must be carried out before production:
Preheating of launders, distributors and boat packages. Connect the prepared burner to the natural gas, ignite and evenly preheat for 30 minutes
Brushing of runner talcum powder. Brush the inner wall of the launder with the prepared talcum powder to reduce the burning rate of molten aluminum and protect the launder.
Brushing of ingot mold coating. The ingot mold coating is evenly brushed on the casting mold, which has the effect of demoulding and can also prevent the explosion of molten aluminum caused by the wet mixing of the casting mold.
