British Richard (Richard) company adopts thermal regeneration, which can increase the regeneration rate by about 10% to 20%. Moreover, the cost recovery period of the thermal process used sand recycling equipment is relatively short, and the cost can be recovered after two years of operation. The key to the technology is to use excellent multi-stage filtration or centrifugal separation to accelerate the operation process and obtain a purer mold material. MittererC discovered in research on aluminum casting molds. In the United States, the aual consumption of sand used in the foundry industry is about 5 million tons.
The binder can be reused many times without adding a new binder as long as 2. Reasonable use of energy and vigorous efforts to save energy is Nonferrous casting Manufactures an important task of the foundry industry.Old sand recovery and reuse In the industrially developed regions of Europe and the United States, the reuse of used sand has always been a major research topic, and good research results have been achieved, and it has been put into industrial production. After the recovered zircon sand that caot be regenerated by mechanical method is treated by thermal method, the quality of reclaimed sand is better than that of new sand. The water from wet sand cleaning can be reused 85%, and the recovered materials can be reused 100%.
The combination of old sand recycling and wet regeneration is an economical and ideal choice. Thereby effectively extending the life cycle of the casting mold. FoundryAutomation and MEG's binders are in powder form, which are used in aluminum alloy cores, and do not generate gas during storage and pouring, and they have no environmental problems that may be caused by resin binders. For example, if the casting is dry-processed, the binder remains in the sand for activation. Its core technology is PACVD technology, namely plasma chemical vapor deposition. High energy consumption, low energy utilization, serious pollution, and poor economic benefits restrict the development of the foundry industry.
When casting non-ferrous metal parts, iron castings and steel castings.. Energy-saving technologies and energy-saving measures include the following aspects. The core sand is made of 95% sand and 5% binder. 90% of the old sand is recycled and reused, and the quality is close to the new sand. It can fully meet the performance requirements of materials used in highway construction. 2
