Background
Sand casting refers to a casting process that produces castings in sand molds. Steel, iron and most nonferrous alloy castings are obtained by sand casting methods. Because the molding materials used for sand casting are cheap and easy to obtain, the casting mold is simple and convenient to manufacture, and is suitable for single-piece production, batch production and mass production of castings, and is a basic process in casting production for a long time;
the basic raw materials for manufacturing sand molds are foundry sand and sand binders. The most commonly used foundry sand is siliceous sand. If the high temperature performance of the silica sand can not meet the use requirement, special sand such as zircon sand, chromite sand, corundum sand and the like is used. In order to make the manufactured sand mold and core have certain strength, the sand mold and the core are not deformed or damaged during carrying, shaping and pouring liquid metal, a molding sand binder is generally added in casting, and loose sand grains are bonded together to form molding sand. The most widely used molding sand binder is clay, and various drying oils or semi-drying oils, water-soluble silicate or phosphate, and various synthetic resins can be used as the molding sand binder.
After sand casting is finished, the casting sand is stripped from the surface of the casting, the stripped casting sand is waste sand, the waste sand can be changed into reusable 'new sand' through crushing, screening, burning, cooling and other treatments, the regenerated 'new sand' has low burning decrement, low gas generation amount and lower expansion coefficient, the casting qualification rate can be improved, and the production cost of a foundry is reduced. Meanwhile, the recycling of the waste sand can greatly reduce the usage amount of the new sand and save the material flow cost. In addition, the recycling of the waste sand can also reduce the development of silica sand resources, greatly reduce the emission of foundry waste sand, lighten the pollution to soil, atmosphere and water environment, and the following problems often exist in the process of recycling and crushing the waste sand:
