Ladle Pre-casting

The precast refractory shapes are ideal for making it easy for the industrial users to efficiently make repairs in case of high wear areas within the furnaces. Today, the refractory designs and shapes are conventionally designed to eliminate loses associated with industrial downtime.Precast refractory shapes are pre fired and can be put right into service in your high temperature application.

The precast refractory shapes are ideal for making it easy for the industrial users to efficiently make repairs in case of high wear areas within the furnaces. Today, the refractory designs and shapes are conventionally designed to eliminate loses associated with industrial downtime.

Precast Shapes are manufactured using high quality castable mixes. Insulating, Abrasion Resistant, Low Cement, No Cement, and conventional mixes are available. Alumina contents from 50-99% are available.
Common applications include:
Lintle Blocks
Pier Blocks
Sill Blocks
Jamb Blocks
Hearth Tile
Burner Blocks
Arch Sections
Wood fired Ovens
Trough sections

Our skilled fabricators make custom molds for each application. Most molds are fabricated from steel, but wood and plastic molds are used when appropriate. Carefully selected refractory materials are poured into each mold. Precast Refractory Shapes are oven dried and can be high-fired to maximize performance in your application. We use many of our precast shapes in our own high temperature kilns and furnaces!
