Plastic Mouldable & Ramming Refractories
Ready-to-use refractory solutions for high-temperature industrial maintenance and lining applications
Where castable refractories or refractory bricks are impractical due to complex geometries or the absence of formwork, plastic mouldable refractories and ramming mixes offer an ideal solution. Vitcas provides a wide selection of high-quality, ready-to-use refractory plastics, developed to meet the demanding needs of industries such as steelmaking, power generation, foundries and petrochemical processing.
High-strength plastic refractories for industrial heat environments
Vitcas plastic mouldables are engineered to withstand extreme temperatures up to 1600°C, withstanding heavy wear, high mechanical stress, and corrosive slags. These products are designed to bond well to existing linings and exhibit excellent thermal shock resistance.
Key advantages:
- High alumina content - enhances strength, density, and heat resistance
- Phosphate and clay bonding systems - suitable for both chemical and heat setting applications
- Resistant to abrasion, molten metal, slag and spalling
- Excellent plasticity - easy to shape and install by ramming
- No formwork required - ideal for irregular or hard-to-reach repairs
- Supplied ready to use - reduces downtime and speeds up installation
Applications of plastic mouldable & ramming refractories:
- Boiler and burner repairs
- Forge furnace linings
- Tundish and ladle linings in steel plants
- Patch repairs to existing refractory structures
- Construction of custom burner blocks
- Hearth linings and impact areas
- Gap filling in high-temperature zones
These materials are particularly effective where precast shapes or standard bricks are unsuitable or when a quick, reliable repair is required.
Easy to install with minimal tooling
Vitcas plastic mouldables are typically installed using a pneumatic hammer or bricklayer's hammer, packing the refractory material to the required shape and volume. The working surface is intentionally left rough to aid the removal of steam during firing. After shaping, the refractory is either:
- Directly fired to eliminate moisture and cure the material
- Left to dry naturally and harden before use, depending on installation conditions
After setting, surfaces can be finely trimmed or carved for accuracy, offering great flexibility in maintenance work and emergency repairs.
Product is normally placed using either a pneumatic hammer or a bricklayer's hammer, building the material up to the approximate size that is required. The face of the plastic refractory, which is left rough on the face to enable effortless removal of moisture, is then whittled down to the exact size and shape desired. Next, the work can be vented and can either be fired directly after placement to eliminate moisture or simply allowed to sit in one spot untouched to harden.
Our product range includes:
- Plastic mouldable refractories - high alumina, phosphate & clay bonded
- Chemical/heat setting ramming mixes - ideal for repairs and monolithic constructions
