Ideally, the refractories should be stored on pallets or racks to prevent contact with the ground and minimize the risk of damage. 2. Handling: It is essential to handle monolithic refractories with care to avoid any physical damage. Refractories should be lifted and moved using appropriate lifting equipment, such as forklifts or cranes, to prevent excessive stress or strain on the material. Avoid dropping or dragging the refractories, as this can lead to cracks or fractures. 3. Packaging: If the monolithic refractories are supplied in packaging, it is important to inspect the packaging for any signs of damage or moisture before accepting the delivery. Damaged packaging can indicate potential damage to the refractory material. If any anomalies are noticed, it is advisable to inform the supplier immediately. 4. Moisture control: Monolithic refractories are susceptible to moisture absorption, which can lead to reduced performance and structural integrity. It is crucial to protect the refractories from direct contact with water or excessive humidity during storage and handling. If refractories become wet, they should be dried thoroughly before use to eliminate any absorbed moisture. 5. Stack height: When storing monolithic refractories, it is important to consider the stack height. Excessive stacking can result in pressure on the lower layers, leading to deformation or cracking. Follow the manufacturer's recommendations for maximum stack height to ensure the refractories' structural integrity. 6. Regular inspection: Regularly inspect the refractory material for any signs of damage or degradation during storage and handling. Look for cracks, spalling, or any other visible abnormalities. If any issues are identified, consult the manufacturer or a refractory expert for guidance on whether the material is still suitable for use. By following these recommended storage and handling practices, you can minimize the risk of damage to monolithic refractories and optimize their performance, ultimately extending their service life and ensuring their effectiveness in high-temperature applications.
