Ladle insulation material introduction

The traditional thermal insulation materials for ladle are gradually replaced by new environmentally friendly thermal insulation materials due to their easy pollution.

Composite reflective insulation boards have gradually been widely used due to their advantages of high temperature strength, extremely low thermal conductivity, low heat capacity, strong thermal stability, safety and environmental protection.

The composite thermal insulation reflector is made of lightweight, inorganic nano-SiO2 with extremely low thermal conductivity (at first as a spacer material, with aluminum foil with high reflection as an interlayer material, and a multi-layer composite structure is formed through a continuous surrounding coating and composite rolling process. The coefficient is smaller than that of static air, and the thermal insulation performance is 15 times higher than that of traditional fiber-based thermal insulation materials. It is the best thermal insulation material so far.
