This characteristic allows the refractories to endure extreme temperatures without experiencing significant deformation or melting. Moreover, monolithic refractories possess exceptional thermal stability. They exhibit low thermal conductivity, enabling them to effectively insulate against heat transfer. As a result, these refractories can maintain their structural integrity even when exposed to rapid temperature changes or thermal shocks. Furthermore, the monolithic nature of these refractories grants them enhanced resistance to thermal stress. Unlike traditional refractory bricks, they lack joints or seams that are susceptible to thermal expansion and contraction. Consequently, they exhibit greater resistance to cracking or spalling when subjected to high temperatures. Additionally, monolithic refractories have the ability to develop a protective layer or slag on their surface when exposed to elevated temperatures. This slag acts as a barrier, preventing direct contact between the refractory material and the hot gases or molten metals. Consequently, the risk of chemical reactions or corrosion is reduced. In conclusion, the combination of high melting point, thermal stability, resistance to thermal stress, and the capacity to form a protective slag makes monolithic refractories highly effective in withstanding high temperatures. They find wide applications in various industries, including steel, cement, glass, and petrochemical, where they encounter extreme heat conditions.
