Calcium Aluminate Binder For Refractory Materials

image.png


Refractory materials use pure calcium aluminate binder, primarily for formulating refractory castables for temperatures ranging from 1500 to 1800°C, and even exceeding 1800°C, especially for low cement and ultra-low cement castables.

CA65P/CA68

  • High CA mineral content, good early strength, high strength
  • Used for formulating refractory castables with ultra-high strength and low cement content, especially for low cement and ultra-low cement castables.
  • Used in the production of ultra-high strength refractory precast blocks.

CA(NA)70

  • Predominantly composed of CA minerals with CA2 minerals as secondary components, exhibiting a favorable CA to CA2 ratio. It has a moderate surface area, good rheological properties, stable performance, and strong resistance to reducing atmospheres.
  • Used for formulating high-purity low-cement refractory castables and high-purity refractory castables.
  • Applied in the production of high-performance refractory precast blocks such as electric furnace covers, iron troughs, narrow bricks.
  • Utilized in the preparation of colored floor mortars, decorative surface mortars, grouting materials, and other construction mortars.

CA70

  • Primarily composed of CA minerals with CA2 minerals as secondary components, featuring a preferable CA to CA2 ratio. It has a relatively higher surface area, providing higher strength and good workability, stable performance, and strong resistance to reducing atmospheres.
  • Suitable for rich cement, medium cement, low cement, and ultra-low cement castables, and can be used as pumpable, shotcrete, ramming, and coating materials.
  • Used in the production of high-performance refractory precast blocks such as electric furnace roof covers, iron troughs, and more.

CA75

  • Product performance falls between CA70 and CA80, with wide applicability.
  • Suitable for rich cement, medium cement, low cement, and ultra-low cement castables.
  • Used in the production of high-performance refractory precast blocks like electric furnace covers and iron troughs.

CA80

  • CA80 has low impurity content, high purity, stable performance, and exhibits high refractoriness and high-temperature resistance.
  • Ideal for high-performance, high-purity low-cement, and ultra-low cement castables.
  • Used in the production of ladle linings, electric furnace covers, iron troughs, and other high-performance refractory precast components.
