Involved in the current of sand mold casting method, adopting adhesive dry sand molding of epc and V method casting, using a binder of sodium silicate sand mold casting is most likely to realize green casting production process. No binder epc has been hailed as a "new casting technology of the 21st century", "green project" in casting, etc; Sodium silicate sand is referred to as the most likely of many experts at home and abroad to realize green sand casting production; And V method casting also because of its energy saving, high efficiency, environmental protection and technical characteristic of high quality and popular, in the 21st century will have broad application prospects. Energy saving and environmental protection is to implement green casting production, the key to realize sustainable development, research and extension must be suitable for the situation of China energy saving, environmental protection new technology and new equipment.
