To withstand the extreme temperatures and thermal shock conditions experienced during continuous casting, monolithic refractories have specific requirements.
First and foremost, these refractories must possess high thermal conductivity, enabling them to efficiently transfer heat away from the molten metal and maintain a stable casting temperature. This is crucial in preventing the formation of defects such as cracks, hot spots, and uneven solidification in the cast product.
Secondly, monolithic refractories for continuous casting applications need to exhibit high refractoriness. This means they can endure the high temperatures of the molten metal without melting or deforming, ensuring the refractories can provide a protective lining and maintain their structural integrity throughout the casting process.
In addition, these refractories must demonstrate excellent resistance to thermal shock. The continuous casting process involves rapid cooling and heating cycles, resulting in significant temperature differentials and inducing thermal stresses. Monolithic refractories with low thermal expansion and high thermal shock resistance can endure these conditions without cracking or spalling.
Moreover, good erosion and corrosion resistance are vital requirements for monolithic refractories in continuous casting applications. The molten metal and slag can be highly corrosive and abrasive, causing wear and chemical attack on the refractory lining. Therefore, refractories with high resistance to erosion and corrosion are essential to ensure the longevity and stability of the lining.
Lastly, monolithic refractories for continuous casting applications should possess good workability and ease of installation. This allows for efficient and precise lining installation, minimizing downtime during maintenance or repairs.
Overall, the specific requirements for monolithic refractories in continuous casting encompass high thermal conductivity, refractoriness, thermal shock resistance, erosion and corrosion resistance, as well as good workability. Fulfilling these requirements guarantees that the refractories effectively safeguard the casting equipment and maintain the quality of the cast products.
