The ceramic foam filter (CFF) molten metal filtration process depends on: alloy type, filter size, casting rate, metal temperature, etc. The grain refiner added before the filter has a particularly adverse effect on the filtration efficiency. In terms of cost and ease of use, ceramic foam filters (CFF) are generally considered to be the acceptable […]

Molten Metal Launders have a long service life. Use a new type of high-silicon melting material that is corrosion-resistant, non-sticky, and does not pollute the molten aluminum. It can meet the requirements of aluminum castings with high added value and high-tech performance. Advantages of Molten Metal Launders High strength, corrosion resistance, impact resistance, good thermal […]

Molten aluminum insulated launders are mainly used for the transportation of molten aluminum with high insulation requirements. The molten aluminum insulation launder combines the properties of organic and inorganic binders and a certain amount of new composite casting materials. These casting materials are insoluble in aluminum and can directly separate refractory and aluminum. Due to […]

The ceramic foam filter will always prevent foreign matter inclusions from entering the molten aluminum casting, and the hardness of the sample filtered by the ceramic foam filter is improved. Ceramic foam filter for molten aluminum is a convenient, cheap and effective method to reduce surface defects of castings. Features of Ceramic Foam Filter Molten […]

Aluminum foundries are using many commercially acceptable melt purification techniques to remove and separate inclusions from molten aluminum alloy before casting. These include different degassing and flux refining methods. Therefore, the quality of the molten aluminum alloy bath depends on the molten metal purification process. It is known that molten aluminum and aluminum-based alloys absorb […]

Commercially used aluminum metal comes from two sources: either pure aluminum extracted from alumina (called primary aluminum), or metal obtained through the recycling of scrap from many sources (called secondary aluminum). In both cases, the metal refining is necessary before it can be used for manufacturing purposes. Oxides form scum, hydrogen is dissolved in metal, […]

Rotary degassing is the most commonly melting treatment method for the foundry, which can effectively reduce metal inclusions and solute hydrogen content. This degassing process is usually used in combination with flux, so that inclusions can be removed more effectively during melt processing. No matter which casting method is used in the manufacturing process of […]

As a new type of porous material, foam ceramics have properties such as strength and hardness, good plastic toughness, corrosion resistance and high-temperature resistance. Ceramic foam filter is made of porous foam ceramics material, it has good mechanical properties and applications, and has achieved good economic benefits in molten metal filtration. Porous foam ceramics have […]

In the production of cast rods, there are defects such as inclusions, segregation, cracks, pores, and porosity. The more serious defects are inclusions, cracks and feather-like crystals. Therefore, under the existing equipment conditions, how to make the quality inclusion defects of the products get effective control is the key to aluminum alloy casting production. Causes […]

Depending on the use of the final product, the level of cleanliness of the molten metal is different. The thinner the final product is required (easy-open cans, heat sinks, etc.), or the higher the surface quality requirements of high-precision strip foil (PS plate base, mirror decorative board, etc.), the higher the requirements for the cleanliness […]
