Applied Research on Shotcrete Technology of Alumina Foam Ceramic Filter Plate 1 Prefacee Foam ceramic is a kind of three-dimensional space grid structure with a high air-void ratio (80% – 90%) porous ceramics, due to their low density, high strength, and high resistance Temperature, corrosion resistance, and good filtration and adsorption. Therefore, it is widely […]
Ceramic filters for aluminum foundry are commonly used to filter various molten aluminum. Ceramic filters for aluminum foundry formed by impregnating organic foam with an aqueous slurry, the slurry composition containing 20%-50% silicon carbide, 20-50% alumina, 1.5-5.0% aluminosilicate fibers, And it has been fired at a temperature of at least 1150°C so that the filter […]
The liquid metal filter was developed in the 1970s. The liquid metal purification technology was first applied to aluminum alloys. Because the melting point of aluminum alloys is low, the density of alloys and oxides are close, and inclusions are difficult to float. Inclusions are the most common casting defect. In casting production, many process […]
Filtering of Molten Aluminum is a method of removing impurities by letting the aluminum alloy melt pass through a filter made of neutral or active materials, so as to separate solid inclusions suspended in the melt. According to the filtering properties, it can be divided into two categories. The filtering method of molten aluminum can […]
Porous ceramic filters filtration efficiency mainly has filtration accuracy, which refers to the particle size of the smallest solid impurity particles in the fluid medium. For ceramic filters, the filtration accuracy can reach 0.1Lm. The main factor that affects the porous ceramic filters filtration efficiency is the maximum pore diameter of porous ceramic filter elements. […]
The ceramic filter plate is an energy-saving and environmentally friendly product, which is widely used in the dehydration process of metal ore operations such as iron, gold, silver and copper. It plays a vital role in energy-saving and emission reduction. For use in most cases, the dry material is generally left for the ceramic filter […]
