How to cast aluminum ingots
The cast aluminum heating to 800 DEG C, then slag, into the mold.
1. coke furnace, graphite crucible.2., scrap aluminum is more miscellaneous, it is easiest to do non-standard ingots. If it can be classified, it can be processed by grade series. Aluminum alloys are all, not pure aluminum ingots.3., process and process can be simple and complex, quality requirements are not the same, but melting, slag removal, degassing, see how to do.4., the simplest treatment is a hodgepodge, simple slag, no need to purify. If the grade, it is necessary to sorting waste, it is a troublesome matter, not suitable for small workshops.
Scrap recycling, scrap for the aluminum content is not the same, so I want to return to the pure aluminum, almost impossible, even if feasible, cost is very high, and we generally refers to aluminum ingots, aluminum ingots for remelting, aluminum content of 99.7%, it is a pure substance. Therefore, after the general scrap steel after quenching and tempering, for direct processing Aluminum Alloy or cast aluminum rod.
