REFRACTORY

Introduction to Refractories: Definition: Refractories are heat-resistant materials used in high-temperature industrial applications to provide thermal insulation, structural stability, and protection against chemical and physical degradation. Importance: Refractories enable the containment and control of high temperatures in industries such as steelmaking, glass manufacturing, cement production, petrochemical refining, and more. Classification of Refractories: Based on Chemical Composition: Acidic refractories (e.g., silica refractories) Basic refractories (e.g., magnesia and dolomite refractories) Neutral refractories (e.g., chromite and carbon refractories) Based on Physical Form: Shaped refractories (bricks, tiles, and precast shapes) Unshaped refractories (monolithic materials like castables, plastics, and ramming mixes) Based on Application Temperature: Conventional refractories (used at temperatures below 1600°C) High-temperature refractories (used at temperatures above 1600°C) ...
