The material is mixed with water or a binder to form a wet mix, which is then propelled onto the surface at high velocity. This technique is commonly used for repairing or lining larger areas and can be done onsite. 3. Ramming: Ramming involves compacting the refractory material into place using a pneumatic or manual ramming tool. The material is typically preheated to reduce moisture content and increase workability. This technique is often used for lining smaller areas or for filling gaps between bricks or precast shapes. 4. Shotcreting: Shotcreting is a technique similar to gunning, but it involves using a dry mix of refractory material. The dry mix is combined with water or a binder just before it is sprayed onto the surface using a high-pressure nozzle. Shotcreting is commonly used for lining larger areas or for creating complex shapes. 5. Troweling: Troweling involves applying the refractory material onto the surface using a trowel or a similar tool. The material is typically a wet mix and is spread and smoothed manually. This technique is often used for patching or repairing small areas or for finishing touches. 6. Vibrating: Vibrating involves using a vibrating tool or a vibrator to compact the refractory material and remove air pockets. This technique is commonly used for improving the density and strength of the monolithic refractory after it has been installed using other techniques. It is important to note that the selection of the technique depends on various factors such as the type of refractory material, the size and shape of the area to be lined, and the specific requirements of the application. Additionally, proper preparation of the surface and adherence to installation guidelines are crucial for ensuring the effectiveness and longevity of the monolithic refractory.
