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.
It is necessary to formulate reasonable process operating procedures, improve the technical level of workers, and enable the correct implementation of process procedures.
