DESCRIPTION
Self-flowing low cement castable is a type of refractory castable that is made of a high-quality raw material blend, including fine-grain alumina, high-grade silicon carbide, and a carefully balanced amount of binders and additives. The composition of self-flowing low cement castable is designed to provide excellent properties such as:
– High thermal shock resistance
– Low permeability
– Excellent abrasion resistance
– Good slag resistance
– High strength at high temperatures
This castable is called self-flowing because it has the ability to flow and spread evenly without the need for any external vibration or compaction. Self-flowing low cement castable has become popular in industries that require high-quality refractory materials because of its ease of installation and excellent physical properties.
The low cement content in the castable makes it ideal for applications where high temperatures are involved, and the refractory material is exposed to extreme environments. Additionally, the low cement content in the castable reduces the amount of water required during installation, making the curing process faster than traditional refractory materials.
Self-flowing low cement castable is commonly used in the iron and steel industry, cement kilns, incinerators, and petrochemical plants. Its unique properties make it ideal for use in areas that require high abrasion resistance, high thermal shock resistance, and resistance to chemicals and corrosion.
