Casting Future Perfection
The research on the superplasticity of the microcrystalline material structure (the average size of the grains usually does not exceed 10 ~ 20μm) is at elevated temperatures and relatively low deformation speed (usually 10-4 ~ 10-3s-1) ongoing.
At present, the most cutting-edge technologies in the world forging industry mainly include plate forging technology, semi-isothermal forging technology, and approximate superplastic technology.
The difficulties of sheet metal processing technology are discussed, improvement measures are proposed, and the application of extension technology in sheet metal processing is also proposed.
From the quality comparison of precision castings, the water glass mold shell is poor, the composite mold shell, silica sol-low temperature wax mold shell is the second, and silica sol-medium temperature wax mold shell is the best.
The purpose of economic analysis of forging processing is to explore the best technical solution and pursue the greatest economic effect. Any production process must not only formulate the process, determine the process parameters and process equipment, but also discuss the economic effect.
Pressure vessels are widely used in industrial production, especially in some dangerous industries, such as chemical industry, industrial manufacturing, high-temperature boilers, etc.
