Alloy steel castings and our daily life are closely related, such as the often used door handles, door locks, radiators, water pipes, wok, gas stove, iron, etc., will use alloy steel castings, the following for everyone What is the impact of alloy steel casting quality factors:
1, alloy steel casting design process, the design, in addition to working conditions and metal materials to determine the performance of alloy steel castings geometric shapes, size, but also from the casting alloy and casting process characteristics to consider the design of the point of view Rationality, that is, the size effect and solidification, shrinkage, stress and other issues, in order to avoid or reduce the alloy steel casting components segregation, deformation, cracking and other defects.
2, reasonable casting process, that is, according to the alloy steel casting structure, weight and size, casting alloy characteristics and production conditions, select the appropriate sub-surface and shape, core method, a reasonable set of casting, cold iron, Pouring system, etc., to ensure access to high quality alloy steel castings.
3, the quality of raw materials for casting, metal charge, refractories, fuels, fluxes, modifiers and foundry sand, sand binder, paint and other materials, substandard quality, will make alloy steel castings pores, pinholes, slag , Sticky sand and other defects, the impact of alloy steel casting appearance quality and internal quality, serious alloy steel castings will be scrapped.
4, process operation, to develop a reasonable process of operation procedures to improve the technical level of workers, so that the correct implementation of the rules.
