Advantages of wear-resistant parts of sand casting crusher

The wear-resistant parts of sand casting crusher are still very common in China, such as jaw plate, high chromium plate hammer, crushing wall, rolling mortar wall, etc., because in the crusher equipment, as a relatively large wear-resistant casting, the accuracy is not very high, especially for jaw plate, the finished products hardly need to be polished by lathe, and the crushing wall, rolling mortar wall and roll skin are only part of the casting that need to be polished by lathe, Therefore, it is particularly suitable for sand casting, because the wear-resistant parts of sand casting jaw plate, high chromium plate hammer, crushing wall, rolling mortar wall, roller skin and so on are more durable than other products such as lost foam casting process by more than 20%. However, lost foam casting has the advantages of high dimensional accuracy, small machining allowance, convenient dry sand dropping, more than 50% reduction in cleaning and grinding workload and labor cost saving. Therefore, the price of lost foam casting is relatively low.

Sand mold is a combination of sand mold and casting core. Because the molding materials used in sand casting are cheap and easy to obtain, and the mold manufacturing is simple, it can adapt to the single piece production, batch production and mass production of castings. For a long time, it has been the basic process in casting production. At present, in the world, 60 ~ 70% of all castings are produced by sand mold, and about 70% of them are produced by clay sand mold.

The main reasons are: compared with other casting methods, sand casting has the advantages of low cost, simple production process and short production cycle. Therefore, castings such as automobile engine cylinder block, cylinder head and crankshaft are produced by clay green sand process. When the wet mold cannot meet the requirements, consider using clay sand surface dry sand mold, dry sand mold or other sand mold. The casting weight of clay green sand casting can range from a few kilograms to tens of kilograms, while the casting produced by clay dry mold can weigh tens of tons. Because sand casting has the above advantages, it is more and more widely used in the casting industry. In the future, it will play an increasingly important role in the foundry industry.
