Among the process parameters associated with pouring characteristics, pouring time and pouring temperature are usually taken as variable parameters of process design. Among them, the pouring time is related to the mold filling speed of liquid metal, and reasonable pouring time can effectively avoid casting defects such as oxidation...
According to the characteristics of sand casting process design, the carbon benefit model is established, which can realize the low-carbon evaluation of sand casting process. In order to further improve the sustainability of the casting process, taking the characteristic carbon benefit of process design as the optimization goal, the...
The carbon dioxide produced in the casting process mainly comes from energy and materials. Quantifying the carbon emission of the casting process can provide a systematic theory and method for the low-carbon research of the casting process. Through the analysis of sand casting process, the carbon emission calculation of...
At present, some scholars divide resource costs into energy, material and labor costs. According to the research boundary of sand casting industry, the casting resource cost in each production department of casting is classified into energy cost, material cost, labor cost and residual cost. The energy cost is mainly...
The production time is calculated from the melting of sand mold casting production stage to the stages of modeling, core making, box closing, pouring, sand dropping and inspection. When multiple equipment are processed at the same time, it is calculated according to the maximum processing time of the process....
The setting of sand casting process parameters is related to the characteristics of casting process design, such as casting dimension tolerance, casting weight tolerance and machining allowance, etc. casting shrinkage, mold slope and minimum casting hole (groove) are affected by casting material, casting structure and mold structure. At the...
Among all the casting processes, sand casting is the most commonly used casting method. The molding materials of casting are cheap and easy to obtain, and the types of casting alloys and the structure and size of castings are almost unlimited. They can not only produce castings with very...
Sand casting is widely used in the forming of iron castings, non-ferroalloy castings and small steel castings, and occupies an important position in all kinds of casting forming methods. The characteristics of sand casting process design are closely related to the selection of casting process scheme and the product...
At present, there are still many problems in China’s manufacturing industry, such as low-carbon manufacturing, energy saving, insufficient investment, low energy efficiency and so on. Among them, many industries have low energy efficiency and carbon emission benefits, especially in the foundry industry. At present, the research on the casting...
The products of traditional manufacturing industry are widely used in various industries, which produce a lot of economic and social value, at the same time, the environmental pollution can not be ignored. According to the International Energy Outlook, industrial energy consumption accounts for more than 80% of the total...
