📏 Expansion Joints (Combustible Cardboard Expansion Gaps 1.5mm, Thermal Expansion)

Rotary Kiln Refractory Brick Expansion Joint Calculator

Calculate circumferential and longitudinal thermal expansion clearances between refractory brick rings: size combustible organic cardboard spacers ($1.0 ext{ to }2.0 ext{ mm}$ thickness) that burn away at $300^circ ext{C}$, accommodate refractory thermal expansion, eliminate brick spalling pinching, and masonry yields.
