Sandwich-type kiln shelf

Sandwich-type Kiln Shelf —— Lightweight, High-Strength Composite Refractory Batts for Energy-Efficient Firing In high-temperature industrial kilns, traditional solid refractory shelves suffer from high thermal mass, slow heating/cooling rates, and heavy weight, leading to excessive energy consumption and sagging under heavy loads. The Sandwich-type Kiln Shelf features an advanced composite structure—typically comprising dense, wear-resistant outer skin layers bonding a
