Recommended refractory materials for different kilns
Cement rotary kiln
Cement rotary kiln is the main equipment for cement clinker calcination and the core part of a modern cement production line. It is a rotating cylinder structure with a certain inclination, which runs continuously at high temperature, pushing the raw materials from the feed end to the discharge end to complete the physical and chemical reaction process.
- High Alumina Bricks – Burning zone & transition zone
- Magnesia-Alumina Spinel Bricks – High corrosion areas
- Low Cement Castables – Preheater & cooler
- Ceramic Fiber Modules – Kiln hood insulation
Glass melting furnace
Glass melting furnace is a high-temperature industrial equipment used to melt raw materials (such as quartz sand, soda ash, limestone, г.д.) into glass liquid. It is one of the most critical core equipment in the glass manufacturing process. The internal temperature of the furnace is usually as high as 1350℃~1600℃, and it can run continuously for several years without interruption. The equipment structure and refractory materials are required to have extremely high resistance to high temperature and corrosion
- Silica Bricks – Crown and superstructure
- Fused Cast AZS Bricks – Glass contact areas
- Zircon Mullite Bricks – Sidewall areas
- Ceramic Fiber Blanket – Backup insulation
Steel Furnaces (EAF, LF, BOF)
Electric Arc Furnace (EAF)
Uses: Using scrap steel as the main raw material, a high-temperature arc is generated by electrodes to melt molten steel.
Features:
Suitable for flexible, small batch, or alloy steel production
Can quickly heat up to above 1600℃
Commonly used in “short process” steelmaking
Mainly uses refractory materials such as magnesia carbon bricks, цэгла з высокім утрыманнем гліназёму, dry ramming materials, г.д.
Ladle Furnace (LF)
Purpose: It is not used for melting, but as an auxiliary equipment for refining, heating, degassing and alloy adjustment of molten steel.
Features:
It can control the composition and temperature of steel
It is often used for low-impurity and high-quality steel
The working environment is a high temperature, but the erosion is light
It usually uses aluminum-magnesium castables, anhydrous ramming materials, magnesium-calcium bricks, and other materials
Basic Oxygen Furnace (BOF)
Uses: Using molten iron as the main raw material, top-blown oxygen is used to oxidize impurities such as carbon to quickly complete the rough refining.
Features:
High efficiency, large output, the main equipment of “long process” steel mills
Violent reaction, strong corrosion to the furnace lining
Refractory material requirements: High corrosion resistance, strong thermal shock resistance, commonly used magnesia carbon bricks, magnesia chrome bricks, г.д.
Lime Kiln
Lime Kiln is a thermal equipment used to calcine limestone (CaCO₃) to produce quicklime (CaO), which is widely used in steel, metallurgy, хімічнай прамысловасці, building materials, papermaking, environmental protection and other industries. Its core working principle is to heat limestone to 900℃~1200℃, decompose it into quicklime and release carbon dioxide gas.
- Magnesia Bricks – High refractoriness under load
- High Alumina Bricks – Preheating zone
- Вогнетрывалы раствор & Castables – Repair and sealing
Incinerator
Incinerator is an industrial equipment used for high-temperature incineration of solid waste or hazardous waste, and is widely used in medical, urban garbage, хімічны, metallurgical, электраэнергетыка і іншыя галіны прамысловасці. Incinerators oxidize and decompose organic matter in waste through high-temperature combustion, and eventually convert it into harmless gas, ash or slag, achieving reduction, harmlessness and resource processing.
- Corundum Castables – High wear & alkali resistance
- Insulating Bricks – Heat retention
- Ceramic Fiber Modules – Secondary chamber lining
