Vitcas Refractory Castable Grade 1600°C-Refractory Concrete

Refractory Castable 1600°C is a high-temperature refractory concrete designed for boiler linings and kiln linings. It is ideal for use in areas exposed to extreme heat, such as around gas or oil burners and locations where forced air is used to generate higher temperatures. Its low iron content makes it particularly suitable for applications in the ceramic and glass industries, where maintaining low impurity levels is essential. This castable refractory is extreme temperature resistant up to 1600°C (2912°F).

Main Uses:

• Lining repairs and relining of commercial/industrial boilers, including straw boilers, waste wood burners, biomass boilers, incinerators, etc.
• Burner blocks in high-temperature zones
• Inside ceramic kilns
• In the brick arches of large steam locomotives

Application Instructions:

• Mixing: Combine the material with the recommended amount of clean, cold water, using clean tools and a clean mixing bucket (or the product's original container).
• Patching and Repairs: Use a trowel to apply the material for small repairs or touch-ups to linings.
• Casting: For burner blocks or custom shapes, coat the wood or metal mould with vegetable oil before applying the castable. Compact the material as much as possible, ideally using vibration, to ensure proper consolidation.
• Curing: After installation, cover the surface with plastic and leave it overnight. After 24 hours, uncover and allow it to dry naturally for 2-3 days at room temperature (approx. 20°C) before removing from the mould.

Pre-heating: As with all refractory castables, thorough drying is essential to remove trapped moisture. Failure to dry the castable properly may result in cracking or, in severe cases, the build-up of steam pressure that can cause the material to shatter. This can be avoided by running the boiler or furnace on a low-heat schedule for several hours, allowing for gradual moisture evaporation.
