With the continuous upgrading of energy saving and emission reduction needs of high-temperature industries such as metallurgy, building materials, chemical industry and so on, Zhengzhou Chaoyu Refractories Co., Ltd. has successfully launched a new generation of lightweight heat-insulating refractory bricks series products with the technological deposits of decades in the field of refractory materials. With the core advantages of ultra-low thermal conductivity, high strength and long service life, the products provide more efficient thermal insulation solutions for industrial furnaces and thermal equipment, and help customers realize the dual goals of cost reduction and efficiency and green transformation.
Technological breakthrough: redefine the performance boundary of heat-insulating refractory materials
The R&D team of Zhengzhou Chaoyu Refractories Co., Ltd. has overcome the technological bottleneck of traditional lightweight bricks with low strength and poor thermal shock resistance by optimizing the design of the material's microporous structure and adopting nano-sized composite aggregate and high-temperature stabilizing bonding agent. The new lightweight heat-insulating refractory bricks have the following core performance:
thermal conductivity as low as 0.15 W/(m-K), thermal insulation efficiency of 40% compared with traditional products;
bulk density of only 0.8-1.2g/cm³, significantly reducing the structural load of the kiln;
long-term use of the temperature of 1,350-1,600 ° C, to adapt to a variety of extreme working conditions;
compressive strength of ≥ 5MPa, service life extension of more than 30%.
At present, the technical indexes of this series of products have reached the international advanced level.
Application scenarios: covering energy-saving transformation of high-temperature equipment in many fields
Zhengzhou Chaoyu Refractories Co., Ltd. lightweight heat-insulating refractory bricks have been successfully applied in many industry benchmark projects:
1. Iron and steel industry: a large iron and steel group used the product to reform the lining of the rolling furnace, the temperature of the outer wall of the furnace dropped by 60 ℃, and the annual savings in gas costs of more than 2 million yuan;
2. Petrochemical field: in the 10-million-ton-size refining and chemical integration project, as the cracking furnace heat insulation layer, it is used as the heat insulation layer of the cracking furnace. Petrochemical field: in a 10 million-ton refining integration project, as a cracking furnace insulation material, reducing heat loss by 15% and helping to cut carbon emissions;
3. New energy track: providing customized insulation solutions for lithium battery cathode material sintering kilns, improving temperature uniformity and increasing product qualification rate by 3 percentage points.
