Product Introduction

To meet the requirements of sections or parts with large temperature changes, high scouring, severe wear and strong erosion in large and medium-sized rotary kilns and other thermal equipment in cement, lime and other industries, the R&D center of our company has spent three years researching and developing a new product — silicon corundum brick. This product features high strength, strong wear and erosion resistance, and excellent thermal shock resistance. It is mainly used in the upper transition zone and cooling zone of large and medium-sized cement rotary kilns.

Product Details

Five Core Advantages of the Product

♦ Energy Saving: Taking a 5000t/d production line as an example, it can save 20 tons of standard coal per day and 5 million yuan for enterprises every year.

♦ High Efficiency: Resistant to scouring and erosion, no brick falling; reduces the number of maintenance times and prolongs the service cycle.

♦ Environmental Protection: Reduces waste heat emission and meets environmental protection requirements.

♦ Heat Insulation: Lowers the cylinder temperature by more than 50℃; protects the safe operation of thermal equipment.

♦ Stability: No cracking or spalling, with thermal shock resistance up to more than 20 cycles (1100℃ → water quenching).
