19 8月 Al Alloy Casting Agent
Al Alloy Casting Agent can play the role of degassing and removing impurities, making the aluminum alloy solution more pure and improving its mechanical properties.
Nitrogen and argon are usually used as carriers for spraying, and a large number of dispersed bubbles are formed in the aluminum alloy solution. During the floating process of the bubbles, the aluminum melt will completely contact and promptly remove the gas and inclusions in the aluminum liquid.
The addition of Al Alloy Casting Agent should be based on the weight of the molten aluminum, because too much or too little will affect the performance of the aluminum alloy, so it must be calculated before adding.
When operating the refining agent, the operator should freely control the refining flow through the barometer and the powder feeder to control the rolling degree of the molten aluminum, thereby reducing secondary pollution.
At the same time, certain substances contained in the refining agent can strongly absorb and melt the oxides and suspended matter in the melt, and adhere to the bubbles, and bring them to the surface of the aluminum liquid as the bubbles rise, thereby achieving Refined. Such as degassing and deslagging. Purpose of purification.
Effectively dispose of aluminum slag generated during casting.
Aluminum slag is an inevitable part of the Melting Aluminum and casting process. Although relevant measures have been taken, a certain proportion of metallic aluminum will still be taken out.
Therefore, smelters need to effectively treat aluminum slag.
The simplest and most economical method is to use a mill to repeatedly grind the aluminum slag and then screen it to effectively recover some aluminum beans.
Pay special attention when spraying. Before adding powder, let in air. Finally, stop the powder before stopping the gas. This is to prevent the aluminum concentrate from clogging the nozzle. If you find that the molten aluminum refining agent has moisture or knots. If it is a square, you can continue to use it by opening the package and drying it in the sun. Sufficient molten aluminum preparation must be added to the surface of the molten aluminum so that the surface of the molten aluminum can be evenly covered to protect the molten aluminum from air oxidation, and the amount to be added is added according to the proportion.
