Ladle preheating is one of the key procedures in steelmaking production. The performance of preheating equipment exerts a significant impact on converter tapping temperature, steelmaking operation rate, furnace campaign life and other indicators. The ladle preheating process sits between steelmaking and continuous casting. The preheating temperature of ladles plays a vital role in coordinating the overall production flow, and carries even greater significance for continuous casting operations.

ALADDIN ceramic fiber modules are mainly applied to the covers of ladle preheaters. The operating temperature of ladle preheaters ranges from 700℃ to 1000℃, while ALADDIN ceramic fiber modules withstand working temperatures of 800℃ to 1250℃. Custom insulation thicknesses from 150 mm to 300 mm are available upon client requirements. Ladle preheaters fitted with this fireproof lining heat ladles faster and enable more precise temperature control of molten steel ladles.

ALADDIN Ceramic Fiber Modules for Ladle Preheaters

Application Advantages

Compared with traditional thermal insulation materials, adopting ALADDIN ceramic fiber modules as ladle preheater lining delivers superior energy-saving and heat retention performance, lighter weight, and stronger thermal shock resistance. The core benefits include reduced operating costs, improved product quality and boosted production efficiency.

Properties of ALADDIN Ceramic Fiber Modules

1. Custom shapes such as square, diamond and fan are available, with multiple layout arrangements to choose from.

2. No expansion joints required. Once binding straps are removed, the modules compress against each other in all directions to form an airtight integral lining.

3. Resists mechanical external force, supporting mobile heating of furnace equipment or off-site transportation.

4. The elasticity of fiber blankets accommodates furnace shell deformation, eliminating gaps between module blocks and furnace steel plates.

5. Excellent thermal shock resistance.

6. The lining requires no drying or curing; the equipment can be put into operation immediately after installation.

7. Anchoring hardware is set back from the hot face of modules, greatly improving anchoring safety.
