Applications
Refractory castables
Monolithic refractory castables are a group of products which with the addition of water, are cast into place. Castables are supplied dry, mixed onsite and installed behind shuttering or cast in a mould to form the required shape.
There are various types of castable products including:
- Conventional
- Low & ultra-low Cement
- Insulating
- Chemically bonded
- Basic
The type of refractory castable you use will depend on the required properties and application.
Gunning materials
Gunning materials are high-temperature refractory materials. These materials are placed using varying types of Gunning equipment through a nozzle with additions of Water and Air. These materials are designed to stick in place and set quickly when applied to the required area, such as walls and roofs.
Due to the nature of their placement using compressed air, the particle size is smaller than general castables, this aids in the reduction of a rebound off the wall.
Our customers use gunning materials in a range of industries from Incineration and Petrochemical, to Iron and Steel business sectors.
Mouldable and Ramming Refractory Products
Mouldable mixes are refractories which are installed by hammering or ramming and have sufficient plasticity to mould to whatever shape is required. Ramming mixes usually contain clay which is tempered with water, de-aired and extruded into blocks.
Ramming mixes contain the same refractory aggregates as mouldable but are supplied in a damp granular form ready for installation using pneumatic rammers. The mix, containing refractory minerals and clay, can also include organic plasticisers.
Refractory Mortars
Refractory mortars can have hydraulic or chemical binders, and our customers use these generally in conjunction with standard refractory bricks of variable shapes and sizes. There are two ways to supply a refractory mortar:
- readily mixed with water
- or dry to be mixed on-site.
