What should be paid attention to when designing stainless steel pipe fittings

不锈钢管件的结构圆角管件壁间连接处均应有铸造圆角。没有圆角的结构,在直角处金属积聚,热节圆比别处大,易产生缩孔和缩松,且内側转角处应力集中严重,易产生裂纹。设计了阀角后,可防止产生上述缺陷。某些金属在直角处晶体宜交,产生晶体间的结合力薄弱,管件在转角处力学性能有所下降,加大了裂纹的产生。所以需将转角处设计成圆角,铸造成圆角更有利于造型,避免铸型尖角损坏而形成砂眼,减少铸件粘砂,使铸件美观等。山东明

The development process of cast stainless steel is introduced in detail

Mold coating is the main component of refractory aggregate is, its ability to resist adhering sand on coating plays a decisive role, and the binder, suspending agent, thickening agent, defoaming agent, surfactant and other additives is the auxiliary material coating, decides the suspension stability of coatings, thixotropy, and intensity of flowing property

There are several annealing processes for wear - resistant castings

Recrystallization annealing is usually referred to as recrystallization annealing because recrystallization occurs once during heating and cooling process. This annealing method is quite common in steel.

Investment casting is a revival of an ancient craft

Lost wax method casting is now called investment casting, is a little cutting or no cutting casting process, is an excellent technology in the casting industry, its application is very wide. It is not only suitable for casting of various types and alloys, but also can produce castings with higher dimensional accuracy and surface quality than other casting methods.
