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

Magnesia-Alumina Spinel Brick — 高アルミナレンガ

Glass melting furnace

Glass melting furnace is a high-temperature industrial equipment used to melt raw materials (such as quartz sand, soda ash, 石灰岩, 等) 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)

電気炉 (EAF)

用途: Using scrap steel as the main raw material, a high-temperature arc is generated by electrodes to melt molten steel.

特徴:

Suitable for flexible, small batch, or alloy steel production

Can quickly heat up to above 1600℃

Commonly used in “short process” 製鋼

Mainly uses refractory materials such as magnesia carbon bricks, 高アルミナレンガ, dry ramming materials, 等.

Ladle Furnace (LF)

目的: It is not used for melting, but as an auxiliary equipment for refining, heating, degassing and alloy adjustment of molten steel.

特徴:

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, およびその他の材料

anhydrous ramming materials — aluminum-magnesium castable

Basic Oxygen Furnace (BOF)

用途: 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.

特徴:

High efficiency, large output, the main equipment of “long process” steel mills

Violent reaction, strong corrosion to the furnace lining

Refractory material requirements: 高い耐食性, 強い耐熱衝撃性, commonly used magnesia carbon bricks, マグネシアクロムレンガ, 等.

Lime Kiln

Lime Kiln is a thermal equipment used to calcine limestone (カコー) to produce quicklime (CaO), which is widely used in steel, 冶金, 化学工業, 建材, 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
耐火モルタル & 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, 化学, 冶金学的な, 電力およびその他の産業. Incinerators oxidize and decompose organic matter in waste through high-temperature combustion, and eventually convert it into harmless gas, ash or slag, 削減を達成します, harmlessness and resource processing.

Corundum Castables – High wear & 耐アルカリ性
Insulating Bricks – Heat retention
Ceramic Fiber Modules – Secondary chamber lining
