Q1: What is the difference between refractory raw materials and refractory materials?
A1: Refractory raw materials: refers to various materials used to make refractory materials, usually unprocessed or less processed substances. These raw materials can be ores, slag, powders or chemicals. They have high temperature resistance, corrosion resistance, wear resistance and other properties, and are suitable for the preparation of refractory materials.
Refractory materials: refer to materials that have been processed or treated to have high temperature resistance, corrosion resistance, wear resistance, etc., and are used in high temperature environments or situations where corrosive media exists. Refractory materials are usually products made of refractory raw materials through sintering, thermal processing, molding and other processes, such as refractory bricks, refractory coatings, refractory ceramics, etc.
Q2: What are the common refractory materials?
A2: Silicate materials: such as ceramics, bricks, tiles, asbestos cement boards, etc.
Refractory bricks: Made of clay or high-aluminum materials, used for high-temperature furnace linings, furnace walls, etc.
Refractory Cement: Used for joining, patching and pouring refractory materials.
Refractory ceramics: With high temperature stability and corrosion resistance, they are often used in stoves, chemical equipment, etc.
Fire-resistant glass: It has high temperature resistance and is used to make laboratory vessels, oven doors, etc.
Refractory fiber: such as ceramic fiber, asbestos fiber, etc., used for heat insulation, heat preservation and fire protection.
Fire-resistant coating: used to coat the surface of metal, wood and other base materials to improve its fire-resistant performance.
Refractory concrete: Mixed with special cementitious materials and aggregates, it is used in building structures and foundations in high-temperature environments.
