Application analysis of cast iron profiles

2020-12-18

Since the horizontal continuous casting process can obtain a relatively dense matrix structure, the oil pressure resistance and air tightness of horizontal continuous casting profiles are higher than other engineering materials. It can be said that the use of horizontal continuous casting profiles to make hydraulic parts is an ideal material so far . In addition to high production rate and low production cost, it also has better machining performance than steel. This is because in the cutting process, the cutting resistance is reduced due to continuous chipping.

Surface and internal quality inspection methods of castings

2020-12-18

The inspection of castings mainly includes size inspection, visual inspection of appearance and surface, chemical composition analysis and mechanical performance test. For castings that require more important requirements or are prone to problems in the casting process, non-destructive testing is also required. It can be used for ductile iron castings. Non-destructive testing techniques for quality testing include liquid penetration testing, magnetic particle testing, eddy current testing, radiographic testing, ultrasonic testing, and vibration testing.

Casting process in foundry

2020-12-17

Casting is a process in which metal is smelted into a liquid that meets certain requirements and poured into a casting mold. After cooling, solidification and cleaning, a casting with a predetermined shape, size and performance is obtained. Because the casting blank is almost formed, it can achieve the purpose of avoiding machining or a small amount of processing, reducing the cost and reducing the time to a certain extent.
