16 6月 Cambodia China Foundry Filter
Cambodia China Foundry Filter is formed by high-temperature sintering, forming interconnected openings on its outer surface and inside. When the fluid passes through the microporous channel, suspended solids, colloidal particles and macromolecular organic matter are captured on the surface of the product. The fluid passes through the microporous channel to produce various physical and chemical effects, which are used for purification and filtration of aluminum rods in aluminum casting plants.
There are many reasons for aluminum pollution. During the smelting process, aluminum is exposed to the atmosphere in the furnace in a molten or semi-molten state.
Easy to oxidize, easy to react with water vapor to absorb hydrogen, easy to form various forms of non-metallic slag. On the other hand, in the recycling process, part of the scrap in the composition fee contains some non-aluminum impurities.
Because the waste comes from process waste, waste from various processes in the factory, and waste outside the factory, the route is different, the composition is complicated, and the quality is poor.
The molten aluminum filtration method using the Cambodia China Foundry Filter is characterized by pouring molten metal into the ceramic material at a rate of 5.0 to 50 cubic inches per minute per square inch of filtering area.
For aluminum, the filtration area per minute is preferably 10 to 30 cubic inches per square inch.
In a normal aluminum casting operation, the minimum metal flow rate is approximately 200 pounds.
No more than 2000 pounds per minute. Metal flow rate per minute, a typical bulk metal flow rate is about 500 pounds.
Ceramic materials are very suitable for successful operation with bulk metal flow rates.
Generally speaking, for aluminum, the specific flow rate of the metal in the filter should not exceed 5 pounds.
The metal filling volume per square inch per minute of the filter section is preferably less than 3 pounds. Per square inch per minute.
Ceramic Foam Filter Aluminium has excellent thermal shock resistance, high strength, high porosity and large specific surface area.
It can filter and absorb as few inclusions in molten metal as possible.
With a unique rectification function, it can prevent laminar flow from flowing smoothly and quickly and prevent bubbles from entering. It is suitable for the different requirements of the casting industry on refractoriness and casting speed.
30 Ppi foam filter can significantly improve the quality of castings, promote cutting, reduce tool wear, and reduce manufacturing costs.
Cambodia’s mineral deposits are mainly gold, phosphate, gems and petroleum, as well as a small amount of iron and coal. Forestry, fishery, and fruit trees are rich in resources.
It is rich in tropical trees such as teak, ironwood, red sandalwood, black sandalwood, and Baimao, as well as a variety of bamboos. The forest coverage rate is 61.4%, mainly distributed in the eastern, northern and western mountainous areas.
The timber reserves are about 1.1 billion cubic meters. Tonle Sap Lake is the largest natural freshwater fishery in Southeast Asia and is known as the “Fish Lake”.
The southwest coast is also an important fishing ground, which produces many fish and shrimps. With imbalances in the ecological environment and overfishing, aquatic resources are declining.
