耐火物とボイラーで使用される耐火レンガの違い

Boilers are common thermal equipment used in many industries such as metallurgy, 電気, and building materials to provide heat sources. Different industries choose different types of boilers. Regardless of the type of boiler, it needs to burn materials to provide heat sources for recycling. The boiler lining needs to have wear-resistant refractory materials. Whether it is refractory bricks or refractory castable masonry, it must meet the use requirements of the boiler lining.

Boiler refractory castables

Refractory castable is a kind of amorphous refractory material. It is a granular material formed by mixing refractory raw materials such as refractory aggregate and refractory powder with binder admixtures. 使用時, add the appropriate amount of water, stir as required, and then pour into the installed mold. 硬化後に使用します, ベーキング, 成形, およびその他のプロセス.

Refractory castables can produce suitable casting materials according to the boiler’s application location. By selecting high-quality raw materials, various refractory castables can be processed, such as high-alumina castables, mullite castables, corundum refractory castables, 等.

Types of boiler wear-resistant castables?

Wear-resistant refractory castables for boilers are generally high-aluminum wear-resistant castables and corundum wear-resistant castables. The appropriate refractory castable can be selected for casting the lining according to the requirements of the used part.

ボイラー用耐火レンガ

Refractory bricks are the main refractory materials used in industrial furnaces. 耐火レンガは、使用現場の要求に応じて、主耐火原料として高品質の耐火骨材を数種類選択して製造できます。, 粉を加える, バインダー, 等, 撹拌, プレスして成形する, 乾燥, 高温の窯に入れて焼成します. 耐火レンガは石積み現場に応じてさまざまなレンガ形状に設計できます。, 耐火泥は耐火レンガを接着するために使用されます. 耐火レンガは需要に応じて必要な厚さに構築できます.

ボイラー用の耐火レンガも耐摩耗性の原則に従う必要があります, 侵食抵抗, 耐熱衝撃性, 等. They need to have high-temperature performance and resist long-term scouring and erosion by materials and airflow placed in the boiler.

Advantages of refractory bricks and refractory castables in boilers

The advantages of refractory castables for boilers are a short production cycle and easy construction. They can be poured according to the construction site and construction requirements. しかし, 建設プロセスの方が重要です. The quality of construction is closely related to the long service life of the lining cast by refractory castables for boilers.

The advantages of boiler 耐火レンガ are convenient masonry, 石積みの内張りの良好な完全性, 耐火物原料は焼成プロセス中に完全に統合されます。. 焼成した耐火レンガはスラグの浸食に対する耐性が向上します。. しかし, the requirements for boiler refractory bricks are high and the price of refractory bricks is relatively expensive.

From the difference between refractory castables and refractory bricks, in the long run, it is better to choose refractory castables for boiler refractory materials.
