Welcome to inquire! Contact: Yuan Xi Chuan. Casting quality including the appearance of quality, intrinsic quality and quality in use. Quality refers to the appearance of the casting surface roughness, surface defects, size deviation, shape bias, weight deviation; mainly refers to the intrinsic quality of the casting of the chemical composition, physical properties, mechanical properties, microstructure and the presence in the cast of the interior holes, cracks, inclusions, segregation, etc; refers to the use of quality castings to work under different conditions of endurance wheel guard Hom, including wear, corrosion, spalling, fatigue, shock-absorbing properties and machinability, weldability and other process performance. Many factors affect the quality of care casting wheel bucket price, the first is the casting of the design process. When the design, in addition to determining the casting geometry, size according to the working conditions and material properties of the metal, but also from the point of view must be cast alloys and casting characteristics to consider the design is reasonable, that is a significant size effect and solidification shrinkage , stress and other problems, in order to avoid or reduce segregation castings, deformation, cracking and other defects generate. The second to have a reasonable casting process. Casting structure that is based on the weight and size, cast alloy wheel guard and production conditions Hom manufacturers, to select the appropriate sub-surface and shape, making the core method, a reasonable set of cast bars, cold iron, riser and pouring system. In order to ensure access to quality castings. The third is the casting quality of raw materials. Quality metal charge, refractories, fuel, flux, modifier and foundry sand, sand binder, paint and other materials, substandard care pier round bucket, make casting porosity, pinholes, slag, sticky sand and other defects, affect the appearance and internal quality casting, casting serious cause scrapped. The fourth is the process operation, to develop a reasonable process rules to enhance the skills of the workers, so that technical rules properly implemented.
