低水泥澆注料：高溫工業的堅實護盾，解鎖耐火新材料密碼 —— 宜興市偉民陶藝廠產品推薦

一、低水泥澆注料制作工藝

低水泥澆注料的制作工藝是確保其高性能的基礎。首先，精選優質原材料，包括高純度的水泥、骨料和

粉料，以及各類添加劑。在配料環節，嚴格控制各成分的比例，確保精準無誤。攪拌過程中，采用先進

的攪拌設備，使各種材料充分混合均勻，形成具有良好流動性和穩定性的澆注料混合物。澆注成型時，

根據不同的應用需求，選擇合適的模具和澆注方法，確保澆注料能夠緊密填充模具，形成所需的形狀。

最后，經過精心的養護和燒結，使澆注料達到理想的強度和性能。

二、材料組成成份

低水泥澆注料主要由水泥、骨料、粉料和添加劑組成。水泥作為膠結材料，為澆注料提供早期強度和粘結

力；骨料是澆注料的骨架結構，決定了材料的耐磨性和抗壓強度；粉料能夠填充骨料之間的孔隙，提高材

料的密實度和強度；添加劑則根據不同的需求，調節澆注料的性能，如減水劑、

促凝劑、防爆劑等。

三、匹配應用行業

低水泥澆注料廣泛應用于冶金、水泥、電力、玻璃、陶瓷等行業。在冶金行業，可用于煉鐵高爐、煉鋼轉

爐、鋼包、中間包等設備的內襯；在水泥行業，適用于回轉窯、預分解窯、窯頭罩、冷卻機等部位；在電

力行業，可用于電站鍋爐的爐膛、燃燒器、煙道等；在玻璃行業，適用于玻璃熔窯、池壁、底、流液洞等

關鍵部位；在陶瓷行業，

可用于陶瓷隧道窯、輥道窯、梭式窯等窯爐的內襯和碹頂。

四、窯爐、鍋爐及其他防腐類設備應用部位

在窯爐方面，低水泥澆注料常用于窯爐內襯、拱頂、窯底、窯墻等部位，能夠有效抵抗高溫火焰的沖刷和物

料的磨損，同時具備良好的隔熱保溫性能。在鍋爐領域，應用于爐膛、爐頂、水冷壁、過熱器、省煤器等部

位，保障鍋爐的安全穩定運行。對于防腐類設備，如化工、石油、造紙行業的防腐儲罐、反應釜、煙道、煙

囪等，低水泥澆注料能夠抵御酸堿鹽等化學腐蝕，延長設備使用壽命。

五、使用方法以及注意事項

（一）使用方法

1. 施工前準備：檢查施工環境，確保溫度、濕度適宜；準備好攪拌設備、模具、振搗工具等；對原材料進行

檢驗，確保無受潮、結塊等現象。

2. 攪拌：按照規定的比例將水泥、骨料、粉料和添加劑加入攪拌機，干拌均勻后，再加入適量的結合水，

攪拌至混合料均勻無團塊。

3. 澆注：將攪拌好的混合料倒入模具中，采用分層澆注的方式，每層厚度控制在 200 - 300mm，使用振

搗器振搗密實。

4. 養護：澆注完成后，根據環境條件進行自然養護或蒸汽養護，保持一定的濕度和溫度，確保澆注料的

強度發展。

5. 烘烤與升溫：按照制定的烘烤與升溫曲線，逐步提高溫度，使澆注料充分燒結，達到使用要求。

（二）注意事項

1. 施工過程中應嚴格控制加水量，避免因加水量過多或過少影響澆注料的性能。

2. 攪拌時間要充分，確保混合料均勻，但也不能過度攪拌，以免影響材料的和易性。

3. 澆注時要分層振搗，確保澆注料密實，避免出現蜂窩狀結構。

4. 養護期間要防止風吹、日曬和雨淋，保持養護環境的穩定。

5. 烘烤與升溫過程中要嚴格按照曲線操作，避免因升溫過快導致澆注料產生裂紋或剝落。

Low Cement Castable: A Durable Shield for High-Temperature Industries – Product Recommendation

 from Yixing Weimin Ceramics Factory

1. Low Cement Castable Manufacturing Process

The manufacturing process of low cement castable is the foundation for its high performance. First, high-quality raw materials are carefully selected, 

including high-purity cement, aggregates, and powders, as well as various additives. During the batching process, the proportions of each component 

are strictly controlled to ensure accuracy. In the mixing process, advanced mixing equipment is used to thoroughly mix the various materials, f

orming a mixture with good fluidity and stability. During casting, suitable molds and casting methods are chosen according to different application 

requirements to ensure that the castable tightly fills the mold and forms the desired shape. Finally, after careful curing and firing, the castable achieves

 the ideal strength and performance.

2. Material Composition

Low cement castable mainly consists of cement, aggregates, powders, and additives. Cement acts as a binder, providing early strength and adhesion

 to the castable; aggregates form the framework of the castable, determining its wear resistance and compressive strength; powders fill the gaps 

between aggregates, increasing the density and strength of the material; additives are used to adjust the properties of the castable according to different 

requirements, such as water reducers, accelerators, and anti-explosion agents.

3. Matching Application Industries

Low cement castable is widely used in metallurgy, cement, power generation, glass, and ceramics industries. In the metallurgical industry, it can be 

used for the lining of blast furnaces, steelmaking converters, steel ladles, and intermediate ladles; in the cement industry, it is suitable for rotary 

kilns, pre-decomposition kilns, kiln hood, and coolers; in the power generation industry, it can be used for the furnace chamber, burners, and flues

 of power station boilers; in the glass industry, it is suitable for glass melting furnaces, pool walls, pool bottoms, and flow channels; in the ceramics 

industry, it can be used for the lining and arch top of ceramic tunnel kilns, roller kilns, and shuttle kilns.

4. Application Parts for Kilns, Boilers, and Other Corrosion-Resistant Equipment

In kilns, low cement castable is commonly used for kiln lining, arch top, kiln bottom, and kiln walls, effectively resisting the scouring of high-temperature 

flames and wear from materials, while also having good thermal insulation properties. In the field of boilers, it is used for the furnace chamber, furnace 

top, water-cooled walls, superheaters, and economizers, ensuring the safe and stable operation of boilers. For corrosion-resistant equipment, such as 

corrosion-resistant storage tanks, reactors, flues, and chimneys in chemical, petroleum, and papermaking industries, low cement castable can resist the 

corrosion of acids, alkalis, and salts, extending the service life of equipment.

5. Usage Methods and Precautions

(1) Usage Methods

1.  Preparation before Construction: Check the construction environment to ensure suitable temperature and humidity; prepare mixing equipment,

2. molds, and vibration tools; inspect raw materials to ensure they are not damp or clumped.

3. 
   

2. Mixing: Add cement, aggregates, powders, and additives to the mixer according to the specified ratio, dry mix evenly, then add an appropriate amount 

of bonding water, and mix until the mixture is uniform and lump-free.

3. Casting: Pour the mixed material into the mold, using a layered casting method with each layer thickness controlled at 200-300mm, and vibrate with 

a vibrator to ensure density.

4. Curing: After casting, cure naturally or with steam according to environmental conditions, maintaining a certain humidity and temperature to ensure the

 strength development of the castable.

5. Baking and Temperature Increase: Gradually increase the temperature according to the baking and temperature increase curve to fully fire the 

castable and meet the usage requirements.

(2) Precautions

1. Strictly control the amount of water added during construction to avoid affecting the performance of the castable due to excessive or insufficient water.

2. The mixing time should be sufficient to ensure the mixture is uniform, but over-mixing should be avoided to prevent affecting the workability of the material.

3. During casting, layer-by-layer vibration should be used to ensure the density of the castable and avoid a honeycomb structure.

4. During the curing period, protect from wind, sun, and rain to maintain a stable curing environment.

5. During the baking and temperature increase process, strictly follow the curve to avoid cracks or spalling of the castable due to rapid temperature increase.
