The centrifugal casting process is used to produce rotationally symmetrical, hollow bodies such as tubes or bushings. Liquid steel is poured into a rotating mould, which solidifies without cavities under high centrifugal acceleration. The centrifugal casting process is used both, horizontally and vertically. The horizontal process is suitable for pipes with a constant wall thickness, while the vertical process is particularly suitable for rings or externally shaped components such as cones.
The outside diameter of a centrifugal casting component always depends on the inside diameter of the mould used. Especially for small quantities, a favourable price depends on the availability of a suitable mould.
Centrifugal Casting Process: horizontal and vertical
Main Quantities: From 1 to 1000 tubes per order
Alloys: heat and corrosion resistant stainless steel
Length: up to 6000 mm
Outer Diameter: from 50 to 2000 mm
weight per casting: up to ~ 3 t
In particular for components in high-temperature environments, cast alloys are superior to wrought materials from other manufacturing processes due to its high creep rupture strength. The high creep rupture strength of heat resistant chromium-nickel materials is based in particular on the formation of carbides and thus depends largely on the carbon content. While this content is limited in wrought materials in order to keep the material deformable, centrifugal casting (and other casting processes) allows the final contour to be produced directly and thus a considerably higher carbon content may be used. In addition to simple tubes, as cast or machined, we supply ready-to-install components or welded assemblies according to your drawings. Typical pressure-resistant products for process plants are tubes, coils and collectors for steam crackers or catalyst tubes and headers for steam reformers. The focus in the non-pressure-resistant area is on furnace rollers and radiant heating tubes for the heat treatment and steel industries.
