INDUSTRY COMPONENT

Thermal Barrier Coating

Thermal barrier coating applied to continuous casting mold copper plates to reduce heat transfer and extend component lifespan.

Component Specifications

Definition
A specialized ceramic-based coating system applied to the surface of continuous casting mold copper plates to create a thermal insulation layer. This coating reduces heat transfer from molten steel to the copper plate, minimizing thermal stress, preventing premature wear, and maintaining consistent cooling rates during the continuous casting process.
Working Principle
Works by creating a low thermal conductivity ceramic layer (typically yttria-stabilized zirconia) between the molten steel and copper substrate. This layer reduces heat flux through the copper plate, allowing for more controlled solidification of steel while protecting the copper from thermal fatigue and erosion.
Materials
Multilayer system: Bond coat (MCrAlY alloy), Thermal barrier layer (7-8% yttria-stabilized zirconia, YSZ), Top coat (optional sealant). Thickness: 200-500 μm.
