Iron casting is a general term for items cast from molten iron. The quality of iron casting includes appearance quality, internal quality, and use quality. So what are the quality factors that affect iron casting? Let's go take a look next.
Here is the content list:
The design process of iron casting
Iron casting must have a reasonable cast iron casting process
The quality of raw materials for iron casting
When iron casting is designed, in addition to determining the iron casting geometry and size 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 casting process characteristics, that is, the obvious side effect and Solidification, shrinkage, stress and other issues to avoid or reduce the occurrence of iron casting defects such as component segregation, deformation, and cracking.
Iron casting must have a reasonable cast iron casting process cast, that is, according to iron casting structure, weight, and size, casting alloy characteristics and production conditions, select the appropriate parting surface, shape, and core making method, and reasonably set the casting ribs, cold iron, riser and gating system, etc. To ensure high-quality iron casting.
The quality of metal charge, refractory materials, fuels, fluxes, modifiers, foundry sand, sand binders, coatings, and other materials are substandard, which will cause iron casting defects such as pores, pinholes, slag inclusions, and sand sticking, which will affect iron casting the appearance quality and internal quality will cause the iron casting to be scrapped in serious cases. The fourth is the process operation. It is necessary to formulate reasonable iron casting process operating procedures, improve the technical level of workers, and enable the correct implementation of the process regulations.
In iron casting manufacturing, the quality of iron casting must be controlled and inspected. First of all, we must formulate process rules and technical conditions from raw materials and auxiliary materials to the control and inspection of each specific product. Each process is strictly controlled and inspected by the process rules and technical conditions. Finally, the quality of the finished iron casting is inspected. To be equipped with reasonable testing methods and appropriate testing personnel. Generally, for the appearance quality of professional iron casting, comparison samples can be used to judge the surface roughness of iron casting, and the fine cracks on the surface can be inspected by the coloring method and the magnetic particle method.
