Aluminum Refining Flux should be added in proportion. The aluminum refining agent is generally 0.3% of aluminum alloy. Method Use a seamless steel pipe inserted 20cm from the bottom of the molten aluminum, and spray the refining agent with nitrogen or argon. After the refining spray, the nitrogen or argon is blown for another 15-20 […]

Degassing Aluminum with Nitrogen: Nitrogen enters the bottom of the aluminum liquid through a certain process device. The nitrogen floats up from the bottom of the aluminum liquid in the form of bubbles. Due to the hydrogen partial pressure difference at the contact interface between the bubble and the molten aluminum, the partial pressure of […]

Flux Refining Operation is necessary for improving the effect of refining, slagging and degassing, the following items should be paid attention to in flux refining operation. Flux Refining Operation There are many metal flux manufacturers to choose the appropriate refining agent, and there are also many varieties of metal fluxes. You can choose a suitable […]

CFF Filter Media is the final filtration step. This is a single-use disposable filter with a strictly controlled pore size. Due to their simple operation and good short-term results, these are usually the only filtration equipment in many foundries. The three key parameters of CFF filter media are: Filter area: the larger the area, the […]

The biggest cause of casting defects is the mixing of impurities (including dross, slag, metal oxides, reaction products of inoculants and spheroidizing agents, casting sand, etc.). The use of ceramic foam filters for aluminum can greatly reduce such impurities, not only can reduce the appearance of castings after demolding, but also reduce the production of […]

As the carrier of the filter, the performance of the reticulated polyurethane foam plastic directly affects the Foam Ceramic Filter Manufacturing Process. It should have the following characteristics: The mesh is uniform to ensure the free penetration of the ceramic slurry and the coating is uniform. The hydrophilic property can firmly Absorb the slurry. Sufficient […]

Aluminum liquid purification equipment configuration of the melting and casting production line mainly includes the refining technology of the holding furnace vent plug in the furnace, so that the aluminum liquid can be effectively purified in the holding furnace. The aluminum liquid obtains good purification indicators before entering the degassing system and the CFF filter […]

The ceramic fiber blanket is made of special aluminum silicate fiber filament by a special double-sided needling process. The interlacing degree, delamination resistance, tensile strength, and surface smoothness of the fiber are greatly improved after the double-sided needling process. The fiber blanket does not contain any organic binder to ensure that the ceramic fiber blanket […]

At present, the refining fluxes are commonly used, and the eutectic NaCl and KCI are commonly used as the main salt system. Adding other auxiliary fluxes properly can improve the efficiency of capturing impurity and degassing in refining flux. In the field of aluminum processing, it is difficult to purify aluminum alloy melt, especially to […]

Deslagging agent is used in metal smelting and casting because it melts at a high temperature above 1200 and has cohesiveness. It can effectively gather and absorb scum and slag inclusion on the surface of the metal solution, and its chemical properties are stable, and it will not cause secondary pollution to the molten metal.
