Steel Shell/Casing Component – Basic Metal Manufacturing

Component Specifications

Definition

A structural steel casing designed to encase and protect the refractory lining of a tundish during pre-heating operations in continuous casting processes. It maintains thermal integrity, provides mechanical support, and ensures safe containment of molten steel at elevated temperatures up to 1600°C.

Working Principle

The steel shell acts as an external protective barrier that contains the refractory lining and withstands thermal expansion stresses during pre-heating. It facilitates uniform heat distribution, prevents heat loss, and maintains structural stability under cyclic thermal loading.

Materials

Low-alloy heat-resistant steel (e.g., ASTM A387 Grade 11/22, EN 1.7335), with chromium-molybdenum content for enhanced oxidation resistance and high-temperature strength.

Technical Parameters

Thickness 12-25 mm
Surface Finish Shot-blasted, anti-scale coating
Design Pressure Atmospheric
Operating Temperature Up to 1600°C

Standards

ISO 9001, DIN 17155, ASTM A387
