Description

Technical field:

[0001] The invention belongs to metal casting equipment, in particular to casting equipment for producing various large, complex, thin-walled, high-quality magnesium alloy castings with strict requirements on dimensional accuracy and density. Background technique

[0002] Reducing the structural weight of various machinery and vehicles is one of the main ways to save energy and protect the environment. Magnesium is the lightest structural metal material. Magnesium alloy is 37% lighter than aluminum alloy. Its specific strength and specific stiffness are second only to titanium alloy and alloy structural steel, but higher than aluminum alloy. Others, such as impact resistance and processing performance, can be The recycling performance is also better than that of aluminum alloy. Magnesium is rich in resources, easy to produce, 9% less energy in smelting than aluminum alloy, 8.5% less energy in melting and casting than aluminum alloy, die-casting mold life is...
