Refractory cement Description
Refractory cement is made of high-quality bauxite and lime as raw materials, and is mixed into raw materials with appropriate ingredients in a certain proportion. After sintering, the clinker with aluminate as the main component is ground into fine powder to make a refractory hydraulic cementitious material. Usually mixed with refractory cement

Production process of refractory cement
A[Raw material procurement] –> B[การเตรียมวัตถุดิบ] –> C[Ingredients] –> D[mix] –> E[Grinding] –> F[Firing] –> ช[cool down] –> H[Crushing] –> ฉัน[filter] –> J[Package] –> K[Finished Product] –> L[store] –> M[การขนส่ง]
- Raw material procurement: procurement of raw materials such as high alumina cement, refractory aggregate, fine aggregate, additives, ฯลฯ.
- การเตรียมวัตถุดิบ: pre-process the raw materials, such as screening, cleaning, drying, ฯลฯ.
- Batching: Accurately weigh various raw materials according to the recipe ratio.
- Mixing: Mix the weighed materials evenly.
- Grinding: Grind the mixed materials into fine powder to increase the reaction area.
- Firing: sintering at high temperature to make the material undergo chemical reaction and form the crystal structure of refractory cement.
- ระบายความร้อน: The sintered material needs to be cooled to room temperature.
- Crushing: The cooled material is crushed into fine powder.
- Screening: Screening is used to ensure that the particle size meets the requirements.
- Packaging: Pack qualified products and prepare them for sale or storage.
- Finished product: The final refractory cement product.
- Storage: The product should be stored in a dry and ventilated warehouse.
- Transportation: Transport products to customers according to order requirements.

Refractory cement VS refractory mortar
ปูนซีเมนต์ทนไฟ：
- Composition: Mainly composed of aluminate cement, high alumina cement or other cement with good refractory properties, and some refractory aggregates may be added.
- แอปพลิเคชัน: Usually used in places where high temperature resistance is required, such as boilers, furnaces, ปล่องไฟ, ฯลฯ. Can be used for pouring or spraying.
- ลักษณะเฉพาะ:
- High temperature resistance (usually over 1000°C).
- Fast solidification.
- High strength and high compressive strength.
- Good chemical resistance.
- Usage restrictions: Due to its high cost, it is usually used in critical areas or where quick repairs are required.
ปูนซีเมนต์ทนไฟ
ปูนทนไฟ：
- Composition: It is mainly composed of refractory materials (such as refractory clay, aluminum silicate, ฯลฯ) mixed with cement or other binders. Different proportions can meet different refractory requirements.
- แอปพลิเคชัน: Mainly used for the joints between refractory bricks, refractory boards and other materials, and can also be used for refractory coatings.
- ลักษณะเฉพาะ:
- The fire resistance can reach different temperatures according to the formula, but it is usually not as high as refractory cement.
- Strong bonding strength, suitable for masonry work.
- Easy construction, good fluidity, easy to fill gaps.
- Relatively poor chemical resistance.
- Usage restrictions: Due to its adhesiveness and fluidity, it is suitable for relatively low temperature environments or as an auxiliary material.
- Refractory cement is more suitable for structural parts that require high strength and high temperature resistance, such as the casting inside the furnace body.
- Refractory mortar is mainly used for masonry and filling gaps to provide bonding between materials.
