Characristeristic:
CA50F :as refractory binder for boilers
★ Fast setting and hardening, concentrated heat release;
★ Formulated with traditional medium and high cement castable, with good construction performance and high construction efficiency;
★ Mainly suitable for general industrial and civil boilers with operating temperature less than 1300ºC.
Aluminate cement A600
★ Fast setting and hardening, concentrated heat release;
★ Formulated with traditional medium and high cement castable, the working performance is better than CA50F;
★ It is widely used in the production of alkali-resistant castable, ordinary high-aluminum castable, and the production of slag retaining balls, etc.
Aluminate cement A700
★ High quality raw material, low content of harmful impurities;
★ Stable setting and hardening performance, with rapid strength development and excellent mechanical strength;
★ Widely used in the production of castable with medium and low cement content, better construction performance and high temperature performance.
Aluminate cement A900
★ It is made of special grade bauxite and high-purity limestone, with high alumina content, extremely low content of harmful impurities, and excellent high temperature resistance.;
★ The setting and hardening performance is stable, with good fluidity, excellent workability, rapid strength development and super high mechanical strength;
★ It is widely used in the preparation of low cement and ultra-low cement castable; it can also be used in conjunction with pure calcium aluminate cement to obtain better medium and high temperature performance, higher resistance to mechanical impact, abrasion and chemical corrosion. It is suitable for the lining of circulating fluidized bed boilers, new type dry cement kiln decomposition furnace, kiln door cover, kiln mouth, heating furnace, soaking furnace lining, etc.
Aluminate cement CA50R
★ Select high-quality raw materials, special formula production, high temperature resistance between A700 and A900;
★ Normal setting, superior construction performance and rapid early strength development, 6h compressive strength can reach more than 30MPa, which can greatly increase the construction speed of castable;
★ It is more adaptable to environmental temperature changes, and can still maintain rapid strength development and earlier demolding time in low temperature environments in winter;
★ Especially suitable for winter construction, emergency repair and other occasions requiring quick release and maintenance.
Our total annual production capacity is about 100,000 tons of dense-shaped refractory product, and 100,000 tons of monolithic refractory product.
We have three tunnel kilns for silicon-aluminum dense bricks and one new plant for the monolithic refractory.
We're sure our custom-made products and professional services will bring you a stable quality supply and more profit.
