How to reduce the aluminum casting loss in the melting and casting process?
In the process of melting and casting of aluminum and aluminum alloys, the level of casting loss directly determines the yield of aluminum. Aluminum casting loss is the general term for non-recoverable metal loss and metals contained in aluminum slag caused by oxidation, volatilization and interaction with furnace walls and refining agents of aluminum and aluminum alloys during the smelting process. The main external manifestations of casting damage can be divided into two parts: one is in the form of pure aluminum ash, and the other is in the form of bulk aluminum, defective aluminum, and aluminum slag. The factors that affect the casting loss are: liquid aluminum temperature; contact strength of aluminum liquid and oxygen; aluminum content in aluminum slag; aluminum liquid brought out by slag scraping; Reduce the contact strength between the liquid aluminum and the air. The greater the contact strength between the liquid aluminum and the oxygen, the more serious the oxidation burning loss and the greater the casting loss. Reduce the contact time between liquid aluminum and oxygen: Under the condition that the production needs are met, the liquid aluminum in the furnace should be turned into a finished product as soon as possible, and...

How do aluminum ingot manufacturers stack aluminum ingots?
The metal characteristics of the aluminum ingot determine its strength and hardness. After the aluminum ingot is processed, it generally needs to be stacked. The aluminum ingot needs to master the correct stacking method. Raw material aluminum is generally cast into ingots, staggered, stacked and packaged for delivery to customers. In the process of stacking or transportation, it is easy to cause the problem of aluminum ingots to slide down due to shaking, resulting in potential safety hazards and increased production costs. So how should I code it? Since aluminum ingots have different models and specifications, the stacking requirements may be different, and different manufacturers will also adopt different stacking methods, which can cross the upper layer of aluminum ingots at 90 degrees. stacked. In the prior art, the placement of aluminum ingots is less manual, and a forklift is used to place the whole stack, but sometimes fewer aluminum ingots need to be placed, and the use of forklifts has the disadvantages of high cost and inconvenience. Mastering the correct stacking method can facilitate the management of aluminum ingots and classify them for storage, which is a faster way. In the process of transporting aluminum ingots, the aluminum ingots...

Casting process flow of die-casting aluminum ingot
Die-casting aluminum ingots play an important role in the industrial field. So how is it casted? Let me give you a brief introduction. In the casting process of aluminum ingots, molten aluminum is injected into the mold, and after cooling into a billet, the injection process is a key step in the quality of the product. The casting process is also the physical process of crystallization from liquid aluminum into solid aluminum. The technological process of casting aluminum ingots is roughly as follows: aluminum production – slag removal – weight inspection – batching – furnace loading – refining – casting – aluminum ingots for remelting – finished product inspection – finished product inspection weight – storage. Commonly used casting methods are divided into continuous casting and vertical semi-continuous casting. Continuous casting can be divided into mixed furnace casting and external casting. All use continuous casting machines. Mixed furnace casting is the process of pouring molten aluminum into the mixing furnace and casting from the mixing furnace. It is mainly used to produce aluminum ingots and casting alloys for remelting. Outer casting is cast directly from the ladle to the casting machine, which is mainly used when the casting equipment cannot...
