Wear-resistant Castings

Casting process methods: lost foam casting, V method casting, sand casting, etc.

Water glass sand casting
The wear-resistant parts of sand casting crushers are still very common in China, such as jaw plates, high chromium hammers, crushing walls, rolling mortar walls, etc., because in the crusher equipment, as a relatively large wear-resistant casting, Relatively speaking, the accuracy is not very high, especially for the jaws, the finished product is almost not polished by a lathe, and the broken wall, rolling mortar wall, roll skin and the like only need to be polished by a lathe, so it is especially suitable for sand casting Because the wear-resistant parts of sand casting jaws, high chromium hammers, broken walls, rolling mortar walls, roll skins, etc., are more than 20% durable than other products such as lost foam casting.
Lost foam casting
Lost foam casting” is also called “gasification mold modeling”, “foamed polystyrene plastic mold casting”, “solid casting” or “cavityless casting”, etc. The essence of this casting method is to use foamed polystyrene plastic instead Ordinary shape, after making the shape, pour the molten metal without taking out the shape. Under the heat of the hot liquid metal, the foam plastic mold vaporizes, burns and disappears, and the molten metal replaces the space occupied by the original foam plastic mold. After solidification, the required castings can be obtained.
V method casting
V method casting and lost foam casting are also known as negative pressure casting, named after the initial “V” of the word “Vacuum” in English. The biggest advantage of it different from traditional sand casting is that it does not use adhesives. V method casting uses plastic film to seal the sand box, and draws out the air in the mold by a vacuum exhaust system. For the required cavity, the casting is solidified by lowering the core, closing the box, pouring and vacuuming, and the negative pressure is relieved, and the casting sand is collapsed to obtain the casting.
Resin sand casting
Resin sand casting is a general term. Molding sand and core sand that have been covered with a solid resin film before molding and core making are called coated sand, or shell (core) sand. Resin sand casting is to mix raw sand and resin to form resin sand. The resin sand is driven into the mold cavity and molded by heating or catalyst. The molded core is then placed in a casting mold for casting. Resin sand castings have the characteristics of small surface roughness, high dimensional accuracy and good quality.

Cast Iron Part

There are many types of iron castings. We can classify iron castings according to different classification standards, and then compare various characteristics between them, so as to apply the best iron castings for production.
Each type of casting can be further divided into different categories according to its chemical composition or metallographic structure. For example, iron castings can be divided into gray iron castings, ductile iron castings, vermicular graphite iron castings, malleable iron castings, alloy iron castings, etc.; molded by casting According to different methods, castings can be divided into ordinary sand castings, metal castings, die castings, centrifugal castings, continuous castings, investment castings, ceramic castings, electroslag remelting castings, bimetal castings, etc. Among them, ordinary sand castings are the most used, accounting for about 80% of all castings. The non-ferrous metal castings such as aluminum, magnesium and zinc are mostly die castings.

Factors affecting the quality of iron castings

Design process of iron castings
When designing, in addition to determining the geometric shape and size of the iron castings according to the working conditions and metal material properties, the rationality of the design must also be considered from the perspective of the casting alloy and the casting process characteristics, that is, the obvious size effect and solidification, Shrinkage, stress and other problems to avoid or reduce the occurrence of defects such as component segregation, deformation, and cracking of iron castings.
Reasonable casting process
That is, according to the structure, weight and size of the cast iron, the characteristics of the cast alloy and the production conditions, the appropriate parting surface and shape, the core making method are selected, and the casting ribs, cold iron, riser and gating system are reasonably set. In order to ensure the acquisition of high-quality iron castings.
Quality of raw materials for casting
The quality of metal charge, refractory materials, fuel, flux, modifier and foundry sand, sand binder, coating and other materials are substandard, which will cause pores, pinholes, slag inclusions, sand sticking and other defects in iron castings, which will affect iron casting The appearance quality and internal quality will cause the iron casting to be scrapped in serious cases.
Process operation
It is necessary to formulate reasonable process operating procedures, improve the technical level of workers, and enable the correct implementation of process procedures.
