What is garden decoration aluminum casting and it can apply for?
It refers to the equipment and devices of pure aluminum or aluminum alloy obtained by casting. Generally, the aluminum or aluminum alloy heated as a liquid is poured into the mold cavity by sand mold or metal mold, and the aluminum parts or aluminum alloy parts of various shapes and sizes are usually called aluminum die casting. The density of cast aluminum alloy is smaller than that of cast iron and cast steel, but the specific strength is higher. Therefore, aluminum alloy castings can reduce the weight of the structure under the same load. Therefore, aluminum alloy castings are widely used in the aviation industry, power machinery, and transportation machinery manufacturing. Aluminum alloy has a good surface luster and good corrosion resistance in the atmosphere and freshwater, so it has a wide range of applications in the manufacture of civil utensils. Pure aluminum has good corrosion resistance in an oxidizing acid medium such as nitric acid and acetic acid, so aluminum casting has certain applications in the chemical industry. Pure aluminum and aluminum alloy have good thermal conductivity. The heat exchange device used in chemical production and the parts required to have a good thermal conductivity in power machinery, such as cylinder head and piston of the internal combustion engine, are also suitable for manufacturing with aluminum alloy.
Garden decoration design
What should be paid more attention to?
I will tell you something about the garden decoration cast part now.EPC steel castings are prone to carbon enrichment defects. At present, there is no good method to completely solve this defect in our country, which is also one reason why many casting manufacturers dare not go to EPC or EPC production line but cannot produce in batch. The main reason for the carbon increase defect is that the foam material contains carbon. During pouring, the foam burns and decomposes free carbon, which invades the molten steel. After tests, it is found that there is a certain regularity in the carbon increase, that is, the surface of the casting increases carbon while the core hardly increases carbon. There is no carbon increase near the inner gate, but the further away from the inner gate, the more serious the carbon increase. The following corresponding measures can be taken to make the casting composition basically within the technological requirements.
