Lightweight refractory castables

Detailed introduction

Lightweight refractory castable is made of lightweight aggregate, high temperature expansion filler, binder and additives, with small bulk density and good heat insulation performance. This material is suitable for the lining of flue, chimney and some hot air pipes of Petrochemical tube heating furnace and rolling heating furnace. The most commonly used lining is the insulation lining of various kilns and thermal equipment.
