Comprehensive refractory service supplier for high-temperature industries
Cement
Key words:
The chrome-free, eco-friendly alkaline refractory products developed by Henan Ruitai are suitable for the burning zone of large and medium-sized new dry-process cement kilns, serving as the preferred protective material for key parts of the kiln.The magnesia-alumina-iron composite brick features excellent thermal stability and erosion resistance, low thermal expansion and thermal conductivity, as well as a flexible structure.
Key words:
Low Thermal Conductivity Mullite Brick
The low thermal conductivity mullite brick is highly adaptable and suitable for key parts such as the calcining zone, tertiary air duct and precalciner of large and medium-sized cement rotary kilns. The product features six core properties: high strength, high wear resistance, high corrosion resistance, high refractoriness under load, low bulk density and excellent thermal shock resistance. Meanwhile, adopting the one-step forming process with a homogeneous structure, it solves the problems of low strength of traditional lightweight materials and mismatched thermophysical properties at bonding parts, achieving a more stable structure. It brings remarkable economic benefits: the kiln surface temperature is reduced by 50–80°C, the fuel consumption per ton of clinker is cut by 1kg; for a φ4.8m rotary kiln with a 40m lining, 1,650 tons of standard coal can be saved annually. It is 10% lighter than silica-mullite bricks and 20% lighter than magnesia-alumina spinel bricks, with a 31-ton reduction in procurement volume for the same lining length, greatly lowering procurement and operation costs.

Six-Resistance Energy-Saving Brick
The Six-Resistance Energy-Saving Brick delivers outstanding energy-saving and carbon reduction effects, helping the cement industry cut costs and boost efficiency, and advancing the achievement of the dual carbon goals.It features six core properties: corrosion resistance, wear resistance, thermal shock resistance, oxidation resistance, thermal load resistance and high-temperature deformation resistance.
Key words:
Alkali-Resistant Brick is a specialized refractory product independently developed by Henan Ruitai, tailored for the preheating system of cement kilns and other alkali-rich working conditions. It integrates five core performance advantages: erosion resistance, excellent alkali resistance, thermal shock resistance, strong corrosion resistance, and anti-coating ability.
