A recent report by World Metals highlighted how Beijing Shougang International Engineering Technology Co., Ltd. (BSIET) assists steel enterprises in saving energy and reducing carbon emissions. The report highlighted that adopting these advanced insulation materials enables precise temperature control during steel production processes, significantly reducing energy consumption, lowering pollutant emissions, and promoting green development. This initiative holds great significance for energy conservation and carbon reduction in the steel industry.

High-temperature steam is a critical energy medium in steel plants, and heat loss during its transportation directly affects overall energy utilization efficiency. Conventional steam insulation materials frequently degrade due to aging and moisture absorption over time. This leads to increased thermal conductivity and, consequently, greater heat loss. Such inefficiencies run counter to steel enterprises' "ultimate energy efficiency" development plans and impede their progress toward achieving energy conservation and carbon reduction targets.

To effectively overcome the limitations of traditional insulation materials, a new type of composite insulation material has emerged, leveraging innovative design principles and advanced material combinations. This novel composite consists of a protective layer, an insulation layer, and a reflective layer. During its manufacturing process, it integrates a variety of specialized components, including thermal insulation materials, heat-resistant materials, reflective materials, micron-scale materials, nano-scale materials, and gas-barrier materials. This sophisticated composition ensures that, even in high-temperature environments, the material effectively suppresses convective heat transfer, thereby minimizing thermal loss. Compared to conventional composite materials, this new product features lower thermal conductivity and an extended operational lifespan.

During the renovation design of the main steam pipeline at a domestic steel enterprise, BSIET fully implemented the new composite insulation material, effectively reducing heat dissipation losses from the steam pipeline and achieving remarkable energy-saving outcomes. The steam transmission capacity of the thermal power generation system was significantly enhanced, resulting in a substantial improvement in power generation efficiency. Additionally, the temperature drop across high-temperature steam pipelines was effectively minimized, contributing to energy conservation and emission reduction. This advancement plays a vital role in helping steel enterprises reduce energy consumption, enhance energy utilization efficiency, and continuously optimize energy performance.

Reports suggest that if major high-temperature steam pipelines in steel plants of varying sizes across China were to adopt this new composite insulation material, the energy-saving effect under equivalent conditions would be remarkable. Such an upgrade would not only further curtail heat dissipation losses and carbon emissions but also significantly boost energy efficiency in steel enterprises, achieving a win-win scenario for both economic and societal benefits. Such an initiative would play a pivotal role in advancing the steel industry's commitment to sustainable green development and aligning with China's overarching "Dual Carbon" strategy.
