They resist basic waste materials and handle heavy physical stress. For example, I’ve seen dense magnesite bricks used to line blast furnaces. They hold up well against lime-rich slags.
Neutral Refractories:
These contain alumina (≥50% Al₂O₃), chromia (Cr₂O₃), and graphite (carbon). They are stable in both acidic and basic conditions. I think they are a great choice for low-oxygen areas, like certain furnace sections.
Acid Refractories:
These products have a high amount of silica. I suggest using them for settings with high corrosion and acid. As a case in point, silica bricks line glass tanks to protect them from acidic slag.
Special Refractories:
This category includes zircon (ZrSiO₄), zirconia-mullite blends, and man-made refractory fibers like blankets and papers. I like that adding zirconia makes these bricks tougher and resistant to sudden temperature changes. This makes them perfect for specific, high-stress jobs.
Structure and Performance
Dense vs. Insulating:
I think of dense refractories as the choice for maximum strength and a long life. They are ideal for blast furnaces and cement kilns. Insulating refractories, on the other hand, are designed to keep heat in. They help cut energy loss and make operations more efficient.
Alumina Content:
I find that low-alumina (<48%) refractories offer more flexibility. I’ve seen them used when working with metals other than iron. For greater strength, I recommend high-alumina (>48%) types. They are popular for linings in the steel and cement industries.
