15 4月 Casthouse Metal Filtration
Casthouse Metal Filtration can remove impurities with a fineness of up to micrometers, and the cast aluminum liquid filter can effectively remove various inclusions in the aluminum water.
Casthouse Metal Filtration can make aluminum horizontally smooth laminar flow, which is conducive to washing, good mechanical strength and chemical stability, and superior aluminum water erosion resistance.
Strictly control the pore size and through-hole rate to obtain a stable filtration effect.
The ceramic foam filter plate is surrounded by a sealed ceramic fiber lining, which helps to seal the filter in the filter box and ensure that there is no side flow of molten metal.
Aluminum liquid casting filter is mainly used in the purification process of aluminum and aluminum alloy production. It can also be used as various gas-solid and liquid-solid separation media, catalyst carriers, burners, sound absorption and environmental protection, etc.
Asian casting filter removes the inclusions in the aluminum alloy melt. Inclusions and gases in the metal have a significant impact on the strength, corrosion resistance and stress corrosion cracking performance of the material.
Effectively controlling the oxidized inclusions in the melt and improving the quality of cast rods and rolled plates have become a common goal pursued by the metallurgical, casting and material industries of various countries.
Its pore size ranges from nanometers to micrometers. Porous ceramic body with high porosity and three-dimensional grid structure. The porosity is between 20% and 95%. It is shaped like tempered foam or porcelain. Sponge, the use temperature is from room temperature to 1600°C.
The production technology of casting filter elements in Asia is becoming more and more advanced, and the technical equipment is becoming more and more mechanized and automated. According to different application purposes, foam ceramic filters of various materials have been developed for different purposes.
Such as A1203, ZrO2, Sic, silicon nitride, boride and other high-temperature foam ceramics, and some also add certain minerals, such as mullite, eastern lapis, fly ash, fly ash, etc. The products are serialized and standardized. A new industry was formed.
Cast aluminum filter has the advantages of melting aluminum
1. High dimensional accuracy, high mechanical strength, stable chemical composition
2. Anti-corrosion, phosphorus-free, environmentally friendly purification of molten aluminum and its alloys, improve the quality of aluminum materials, reduce defects, reduce the rate of defective products, reduce costs, and improve production efficiency.
3. Easy to use, flexible size from 40mm to 600mm, to meet different aluminum water flow.
China is a major producer of aluminum products. The output of aluminum products has always been the world’s largest, but mainly low-end products. With the continuous expansion of market demand, aluminum products must move to high-end. The use of ceramic foam filter plates can improve the quality of aluminum products, improve product quality, and meet the requirements of the high-end market. Therefore, filter plates are required.
It needs to be particularly pointed out that to prevent the secondary pollution of the melt that may occur during the solidification and molding process of the aluminum liquid after leaving the filter box.
In this process, the use of long-life, high-strength, non-stick aluminum, good thermal insulation fused silicon ceramic sintering tank, front box, switchboard, and thermal cover, and timely dehumidification and cleaning to eliminate possible pollution sources.
The Asian Casting Filter is the last process in the purification treatment of aluminum melt. Ensuring the cleanliness of the aluminum melt cannot be ignored.
