Advantages of castings with low cement content

Low cement castings have lower cement content, than conventional refractory castings. The casting is made from refractory aggregate and powder as raw materials, and then the binder and additives are added. Aluminate cement is mainly used as a binder.. Amount of cement, added to the cast material, affects overall performance, strength at high temperatures and resistance to corrosion, etc., therefore, low cement and ultra-low cement castings have better performance.

Castings with low cement content have excellent fire resistance

Low cement casting performs well in high temperature environments. Due to the low cement content, other refractory aggregates and additives in the casting become the main support and structure for solidification, providing superior fire resistance. This makes castings with low cement content suitable for applications, requiring high fire-resistant properties, such as lining of high temperature furnaces, kilns, heat treatment equipment, etc..

Good resistance to thermal shock

Castings with low cement content have higher thermal shock resistance. Due to the lower cement content, there is less stress and shrinkage during the curing process, which reduces thermal stress, caused by temperature changes, thereby improving the resistance of castings to thermal shock and reducing the risk of cracking.

Excellent construction characteristics

Castings with low cement content have good fluidity and ductility, which is convenient for construction work. Compared to castings with high cement content, lower cement content makes pumping easier, pouring and forming castings, increasing construction efficiency.

High wear resistance

Wear-resistant aggregates and wear-resistant additives are commonly added to low-cement refractory castings., to give them excellent wear resistance. This makes it possible to cast refractories with low cement content, which have proven themselves in certain areas of application, requiring high wear resistance, such as equipment for iron and steel smelting, cement kilns, fire-resistant coatings, etc..

Energy saving and environmental protection

Due to the low cement content in the formulation of low-cement refractory casting material, the use of cement is relatively reduced. This helps reduce carbon emissions and environmental impact and meets energy saving and environmental protection requirements.
