Reducer is in all kinds of casting machine casting method for metal forming objects, namely the good liquid metal smelting, casting, injection, inhaled or other casting method into the prepared mold, after cooling after grinding and other follow-up processing means, of a certain shape, size and properties of objects. Casting can be classified into steel casting, iron casting, copper casting, aluminum casting, magnesium casting, zinc casting, titanium casting, etc. Each kind of casting can be further divided into different types according to its chemical composition or metallographic structure. For example, cast iron parts can be divided into gray iron parts, ductile iron parts, vermicular iron parts, malleable iron parts, alloy iron parts, etc. According to cast molding method, can be divided into ordinary the casting sand mold casting, metal mold casting, die casting, centrifugal casting, continuous casting parts, investment casting, ceramic type casting, electroslag casting pieces, double metal castings, etc. Among them, ordinary sand casting has the most applications, accounting for about 80% of the total casting output. And aluminum, magnesium, zinc and other non-ferrous metal castings, mostly die-casting pieces. The casting process of machine tool bed should follow the principle of high temperature furnace and low temperature casting. It is convenient to remove slag and gas, and reduce slag inclusion and porosity of machine tool castings. Using low pouring temperature, is beneficial to reduce the gas solubility in the liquid metal, liquid, shrinkage and high temperature liquid metal baking of cavity surface, avoid adhering sand, the appearance of porosity and shrinkage cavity defects. Therefore, the lower pouring temperature should be adopted as far as possible while the mold cavity is filled. The process of injecting molten metal from the ladle into the mold is called casting. Improper pouring operation will cause insufficient casting, cold insulation, air hole, shrinkage hole and slag, and cause personal injury.
1. Can produce parts with complex shapes, especially the blank of complex inner cavity (such as heating)
2. Wide adaptability, metal materials commonly used in industry can be cast. A few grams to several hundred tons.
3. Extensive sources of raw materials. The price is low. Scrap steel, scrap, chip
4. The shape and size of the casting are very close to that of the parts, which reduces the cutting amount.
