A ceramic foam filter is installed on the CFF filter equipment to filter liquid impurities in the aluminum alloy, so as to meet the production of high value-added, high-tech performance aviation, transportation and other aluminum alloy precision castings.
In the aluminum smelting and casting process, the purity of the aluminum melt is related to the metallurgical quality of the ingot. The most common filtering method is to use a filter plate to filter out the impurities in the molten aluminum. Usually, “casting filter production” is placed directly in the filter frame for filtering. The aluminum liquid filter box is an auxiliary tool that can improve this situation. We put the filter plate in the CFF filter equipment. The molten aluminum has been repeatedly filtered through several layers of filter plates, which greatly improves the performance of the ingot.
Aluminum and its alloys are prone to oxidation and gas absorption during the smelting and casting process, and defects such as inclusions and pores are easily formed during the die-casting process, which is not conducive to the alloy structure, thereby reducing the mechanical properties and corrosion resistance of the alloy, and Reduce production. Therefore, reasonable control of the smelting process and improvement of the quality of aluminum melt are the key to improving the quality of aluminum die castings.
Inclusions and gases in the metal will seriously affect the strength, fatigue resistance, corrosion resistance and stress corrosion cracking performance of the material. Effective control of oxidized inclusions in the melt to improve the quality of cast rods and rolled plates has become a common goal pursued by all countries in the metallurgy, foundry and material industries.
The 30ppi ceramic filter can remove most of the inclusions in the aluminum alloy melt.
CFF filter equipment can filter out impurities, gases and certain harmful elements in the aluminum melt through the filter (main body) in the process of casting or casting salt.
- The principle is adsorption filtration and mechanical filtration.
- It greatly improves the mechanical properties of aluminum alloy filter tip castings, and can increase the strength, toughness and elongation.
- After filtering the molten aluminum, the quality of ingots and castings is also greatly improved.
