Ceramic Foam Filter Pakistan Aluminum uses a set of strict manufacturing technology from material selection, pulp mixing, carrier pretreatment, infrared drying, sputtering coating and microwave drying, and then to the temperature field control of roasting.
In the casting process of aluminum bar and aluminum ingot, the mechanism of foam ceramic plate filtration and purification of aluminum melt is generally described as diffusion interception and inertial impact interception or screening mechanism, sedimentation layer and deep bed filtration mechanism.
The temperature field effect in the process of melting and heat transfer of bar aluminum ingot inevitably results in the difference of alloy solute concentration.
The redistribution of the metal melt is one integration and one integration again and again, which is also a good alloying process. Some high melting point metal phases and compounds reaggregate and grow up, and the small impurity phases aggregate and grow up to be conducive to filtration and capture.
This can be explained by the change of alumina, Fe phase and Ti phase concentration before and after filtration.
For aluminum melt containing more hybrid mass of aluminum liquid, the effect of using two-stage alumina ceramic foam filter plate is more obvious. In this way, the liquid aluminum is more pure and meets the needs of high quality aluminum products.
The foam ceramic filter plate with larger holes and mesh is selected first, and a glass fiber cloth is added in front of the filter plate for coarse filtration. In this case, it is important to use glass fiber cloth for coarse filtration when semi-continuous casting aluminum melt. It can intercept the slag flowing out of the furnace and the residue washed down from the flow trough to prevent the filter plate from being blocked.
The removal rate of the impurity phase in the Ceramic Foam Filter Pakistan Aluminum melt is high, the static pressure difference changes more with the extension of time before and after filtration, and the change of H content in the Aluminum melt before and after filtration is also obvious. Of course, the smaller the hole of foam ceramic plate, the more can improve the cleanliness of aluminum melt.
Ceramic foam filtration is the last process of aluminum melt purification. It is very important to choose the appropriate foam filtration plate.
In particular, it is necessary to prevent secondary contamination of aluminum melt from leaving the filter box until it solidifies.
In this process, the flow tank, front box, distribution plate and hot cap made of molten quartz ceramics with long life, high strength, non-stick aluminum and good thermal insulation are adopted, and the possible pollution source is eliminated by timely dehumidification and cleaning, which can not be ignored to ensure the cleanliness of aluminum melt.
