组件规格

定义
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.
工作原理
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.
材料
Low-alloy heat-resistant steel (e.g.ASTM A387 Grade 11/22EN 1.7335)with chromium-molybdenum content for enhanced oxidation resistance and high-temperature strength.
Thickness
12-25 mm
Surface Finish
Shot-blasted, anti-scale coating
Design Pressure
Atmospheric
Operating Temperature
Up to 1600°C
标准
ISO 9001DIN 17155ASTM A387
