低水泥浇注料：高温工业的坚实护盾，解锁耐火新材料密码 —— 宜兴市伟民陶艺厂产品推荐

一、低水泥浇注料制作工艺

低水泥浇注料的制作工艺是确保其高性能的基础。首先，精选优质原材料，包括高纯度的水泥、骨料和

粉料，以及各类添加剂。在配料环节，严格控制各成分的比例，确保精准无误。搅拌过程中，采用先进

的搅拌设备，使各种材料充分混合均匀，形成具有良好流动性和稳定性的浇注料混合物。浇注成型时，

根据不同的应用需求，选择合适的模具和浇注方法，确保浇注料能够紧密填充模具，形成所需的形状。

最后，经过精心的养护和烧结，使浇注料达到理想的强度和性能。

二、材料组成成份

低水泥浇注料主要由水泥、骨料、粉料和添加剂组成。水泥作为胶结材料，为浇注料提供早期强度和粘结

力；骨料是浇注料的骨架结构，决定了材料的耐磨性和抗压强度；粉料能够填充骨料之间的孔隙，提高材

料的密实度和强度；添加剂则根据不同的需求，调节浇注料的性能，如减水剂、

促凝剂、防爆剂等。

三、匹配应用行业

低水泥浇注料广泛应用于冶金、水泥、电力、玻璃、陶瓷等行业。在冶金行业，可用于炼铁高炉、炼钢转

炉、钢包、中间包等设备的内衬；在水泥行业，适用于回转窑、预分解窑、窑头罩、冷却机等部位；在电

力行业，可用于电站锅炉的炉膛、燃烧器、烟道等；在玻璃行业，适用于玻璃熔窑、池壁、底、流液洞等

关键部位；在陶瓷行业，

可用于陶瓷隧道窑、辊道窑、梭式窑等窑炉的内衬和碹顶。

四、窑炉、锅炉及其他防腐类设备应用部位

在窑炉方面，低水泥浇注料常用于窑炉内衬、拱顶、窑底、窑墙等部位，能够有效抵抗高温火焰的冲刷和物

料的磨损，同时具备良好的隔热保温性能。在锅炉领域，应用于炉膛、炉顶、水冷壁、过热器、省煤器等部

位，保障锅炉的安全稳定运行。对于防腐类设备，如化工、石油、造纸行业的防腐储罐、反应釜、烟道、烟

囱等，低水泥浇注料能够抵御酸碱盐等化学腐蚀，延长设备使用寿命。

五、使用方法以及注意事项

（一）使用方法

1. 施工前准备：检查施工环境，确保温度、湿度适宜；准备好搅拌设备、模具、振捣工具等；对原材料进行

检验，确保无受潮、结块等现象。

2. 搅拌：按照规定的比例将水泥、骨料、粉料和添加剂加入搅拌机，干拌均匀后，再加入适量的结合水，

搅拌至混合料均匀无团块。

3. 浇注：将搅拌好的混合料倒入模具中，采用分层浇注的方式，每层厚度控制在 200 - 300mm，使用振

捣器振捣密实。

4. 养护：浇注完成后，根据环境条件进行自然养护或蒸汽养护，保持一定的湿度和温度，确保浇注料的

强度发展。

5. 烘烤与升温：按照制定的烘烤与升温曲线，逐步提高温度，使浇注料充分烧结，达到使用要求。

（二）注意事项

1. 施工过程中应严格控制加水量，避免因加水量过多或过少影响浇注料的性能。

2. 搅拌时间要充分，确保混合料均匀，但也不能过度搅拌，以免影响材料的和易性。

3. 浇注时要分层振捣，确保浇注料密实，避免出现蜂窝状结构。

4. 养护期间要防止风吹、日晒和雨淋，保持养护环境的稳定。

5. 烘烤与升温过程中要严格按照曲线操作，避免因升温过快导致浇注料产生裂纹或剥落。

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.
