Aluminyo Silicate Ramming Material

Aluminum silicate ramming material is a kind of refractory material with high aluminum and low iron, and its main components are Al₂O₃ and SiO₂. It is made by high-temperature sintering and high-energy grinding or ramming. It has high service temperature, strength, and density, and is mainly used in high-demand refractory structures. Rongsheng Refractory Materials also produces mga castables and customized ramming materials with different compositions.

Production of aluminum silicate ramming mass

In manufacturing, aluminum silicate ramming materials usually need to go through multiple processes, such as screening, drying, mixing, pounding, etc., to ensure uniformity and stability. Its production process and formula can be adjusted according to different needs to achieve the required fire resistance and service life.

Features of aluminum silicate ramming mass

1. High aluminum and low iron: Al₂O₃ content is usually 55-80%, and Fe₂O₃ content is shallow, generally not more than 3%. This can greatly increase the softening point and use temperature.
2. Dense structure: Aluminum silicate ramming material has been rammed to obtain magnificent grain structure and higher density, generally greater than 3.4g/cm³, which greatly improves its strength and slag erosion resistance.
3. High corrosion resistance: The composition of high aluminum and low iron and dense microstructure make aluminum silicate ramming material have strong resistance to acid and alkali and corrosion of various slags.
4. Mataas na lakas: the compressive strength of aluminum silicate ramming material exceeds 600MPa, which enables it to withstand greater mechanical stress and service load.
5. High working temperature: Generally, it can work at a temperature above 1600-1800°C, and the maximum temperature of special varieties can reach above 2000°C.
