Calcium aluminate cement manufacturing

Calcium aluminate cement manufacturing has the characteristics of high early strength, moderate setting time, high fire resistance, strong slag resistance, etc. It is widely used in metallurgy, building materials, petroleum, chemical and other industrial kilns.

Calcium aluminate cement is mainly with natural bauxite or industrial alumina and calcium carbonate (limestone) according to a certain proportion, by calcining or electric melting and made, also useful bauxite and limestone with melting and made. According to its chemical composition can be divided into ordinary calcium aluminate cement (Al2O3 53-72%, CaO 21 ~ 35%) and pure calcium aluminate cement (Al2O3 72 ~ 82%, CaO 19 ~ 23%) two kinds. The chemical composition and mineral composition of different types of calcium aluminate cement manufacturing may vary to some extent.

What we should know is, calcium aluminate cement manufacturing, medium and low grade refractory castables, such as clay, high aluminum castables using ordinary calcium aluminate cement as binder. High-grade refractory castables, such as steel jade, mullite, containing chromium steel jade, corundum – spinel castables using pure calcium aluminate cement as binder. The dosage of ordinary refractory castable calcium aluminate cement is 10%~20%, the dosage of low-refractory castable cement is 5%~7%, and the dosage of ultra-low cement castable is less than 3%.

I plant with an can production of more than ten thousand tons of refractory production line, production automation, production and sales of refractory materials are through the national test, refractory components uniform, high purity, quality stability, welcome to consult and purchase.

Calcium aluminate cement can also be called high aluminum cement. It and portland cement belongs to hydraulic cement. Due to the different mineral composition, calcium aluminate cement manufacturing characteristics are different.

The construction performance of refractory castable is closely related to the process of calcium aluminate cement manufacturing. At the same time, the balance of construction performance and strength is also related to the control of calcium aluminate cement hydration process.

Calcium aluminate cement manufacturing is natural bauxite or industrial alumina and calcium carbonate (limestone) according to a certain proportion of the cooperation, calcined or electrofused and made, also useful iron bauxite and limestone through melting and made. Product quality is stable and reliable, welcome to consult and buy.

Generally speaking, the setting and hardening rate of calcium aluminate cement are also related to the curing temperature. With the increase of curing temperature, the setting and hardening rate of CA2 minerals is accelerated, while CA minerals are somewhat abnormal, which are relatively fast at about 20℃, slow at 30℃, and fast at higher than 30℃. According to the phase transition of calcium aluminate hydrate during heating, it is very important to choose suitable curing conditions. Because the hydration of calcium aluminate cement results in different hydrates with different curing conditions.

This series of refractory cement is widely used in metallurgy, chemical industry, petroleum, electric power, machinery, building materials and other industrial kilns and high temperature equipment. It has a good resistance to sulfate corrosion, good waterproof performance, high early strength, setting and hardening fast and other advantages, all products our company before the delivery of strict quality control, welcome to consult and purchase.
