Product Description
Refractory cement is also known as high-temperature cement. It is made of high-quality bauxite and high-quality lime, both of which are combined with appropriate amount of ingredients in a certain proportion. The refractory degree of refractory cement is not less than 1580℃ (2876℉). It can be divided into aluminate refractory cement, low-calcium aluminate refractory cement, calcium-magnesium aluminate cement, and dolomite refractory cement according to different compositions.
Refractroy Cement CA50
Aluminate cement CA50 series products are based on natural high-quality bauxite and limestone as raw materials, calcined at high temperature to form a clinker with one calcium aluminate (CA) and one calcium dialuminate (CA2) as the main mineral phase, and then ground to the best particle size distribution of water-hard cementitious material.

Power Industry
Refractory cement can also be used in the power industry, such as the fixing and lining of boilers, coal-fired, gas-fired thermal power plant furnaces, tails, and other equipment. KERUI refractory cement can withstand high temperature and flue gas corrosion and erosion, further to ensure the safety and reliable operation of equipment.
Cement Industry
In the cement production process, some high-temperature equipment is required to burn raw materials. This equipment, such as a rotary kiln, cooler, preheater, kiln tail, etc., needs to be fixed and lined with refractory cement, which can withstand the heat generated during high-temperature calcination, protect the kiln structure and prolong the life of the equipment.
Indústria petroquímica
Many pieces of types of equipment in the refining and chemical industry also need to be fixed and lined with refractory cement, such as hydrogenation reactors, rectification towers, steam pipes, flue gas purifiers, etc. Refractory cement can resist high temperatures and corrosion, and protect equipment from acid and alkali, Corrosive gas.
