Product Specification
Castables
Refractory castables are unshaped refractory materials mixed with binders and aggregates, designed to be cast, vibrated, or pumped into place and then cured in situ. They are widely used for lining complex-shaped furnace structures where pre-formed bricks cannot be easily installed.
Applications
- Steel ladle linings and ladle bottoms
- Electric arc furnace (EAF) roofs and tapping spouts
- Blast furnace trough and runner linings
- Cement kiln inlet and outlet zones
- Petrochemical and non-ferrous furnace linings
