Flange Connection Ring Component – Basic Metal Manufacturing

Component Specifications

Definition

The Flange Connection Ring is a critical sealing and fastening component in molten metal flow control systems, typically installed between the nozzle body and the tundish or ladle. It ensures leak-proof connections under extreme thermal and mechanical stresses during continuous casting or metal pouring operations. The ring features bolt holes for secure mounting and a precisely machined sealing surface to prevent metal leakage and oxidation.

Working Principle

The flange ring creates a mechanical seal by compressing a gasket or refractory material between two mating surfaces when bolts are tightened. This compression prevents molten metal leakage while withstanding thermal expansion from temperatures up to 1600°C. The ring distributes clamping forces evenly to maintain seal integrity during thermal cycling and mechanical vibration.

Frequently Asked Questions

What maintenance is required for flange connection rings?

Regular inspection for thermal distortion, crack detection via dye penetrant testing, and surface refurbishment when sealing surface roughness exceeds Ra 6.3 μm. Replace if warpage exceeds 0.2 mm.

How often should flange rings be replaced in continuous casting?

Typically every 3-6 months depending on operating temperature and cycle frequency. Monitor for reduced sealing performance or visible degradation.
