The main reason why monolithic refractories can resist high temperatures is their high melting point. These refractories are made from materials such as alumina, silica, and magnesia, which have high melting points ranging from 1650°C to 2000°C. This means that they can withstand extreme temperatures without undergoing significant deformation or melting. Furthermore, monolithic refractories possess excellent thermal stability. They have low thermal conductivity, which means they can effectively insulate against heat transfer. This property allows the refractories to maintain their structural integrity even when exposed to rapid temperature changes or thermal shocks. In addition, the monolithic nature of these refractories provides them with enhanced resistance to thermal stress. Unlike traditional refractory bricks, monolithic refractories do not have joints or seams that can be vulnerable to thermal expansion and contraction. This makes them more resistant to cracking or spalling when subjected to high temperatures. Moreover, monolithic refractories can form a protective layer or slag on their surface when exposed to high temperatures. This slag acts as a barrier and prevents direct contact between the refractory material and the hot gases or molten metals, reducing the risk of chemical reactions or corrosion. Overall, the combination of high melting point, thermal stability, resistance to thermal stress, and the ability to form protective slag makes monolithic refractories highly effective in resisting high temperatures. They are widely used in various industries, including steel, cement, glass, and petrochemical, where they are exposed to extreme heat conditions.
