Green, low-carbon and intelligent lead the transformation and upgrading of the steel industry

In 2020, MCC South and Hubei University of Technology jointly completed the "Key technology and application of green intelligent energy saving and Consumption reduction in Steel Industry under Complex Manufacturing Environment" won the first prize of Hubei Province Science and Technology Progress Award. Under the support of the national 863 Program and the major science and technology projects of MCC Group, the technical system of energy-saving optimization combustion of BF hot blast furnace has been established, and the software of energy-saving combustion optimization system of BF hot blast furnace has been developed, which can effectively raise the air temperature by 9 ℃-20℃ and reduce the gas consumption by 3%-6%. The key technology of intelligent and low-cost production control of reheating furnace is invented, the furnace temperature setting model based on the billet optimal temperature curve is established, and the energy-saving combustion optimization control technology of various reheating furnaces is developed and the intelligent vision system of automatic loading of steel on the bench is pioneered at home and abroad, which effectively reduces the gas consumption by 4%-6%.

Build a comprehensive governance plan to protect the clear water, blue sky and pure land

MCC South has built a pollution control technology system that integrates source emission reduction, process control and end treatment, uses advanced, mature and efficient waste gas, waste liquid and solid waste treatment technologies, expands new ways of energy conservation and emission reduction, uses scientific and technological innovation to promote the balanced improvement of energy conservation and environmental protection level of iron and steel enterprises, promotes the green development of the steel industry, and helps win the battle of blue sky, clear water and clean land.

High-quality implementation of ultra-low emission transformation, promoting the coordinated emission reduction of conventional air pollutants and carbon, is the most feasible way to reach the peak of carbon at this stage, and can also lay a solid foundation for the next step of carbon neutralization. At present, MCC South has mastered various flue gas desulfurization and denitrification, dust removal and emission reduction technologies in the steel industry. In view of the uneven quality of active coke, the core raw material for desulfurization and denitrification of flue gas sintering machine, MCC South designed a modern active coke preparation process that integrates safety, intelligence, green and high efficiency, and built the first set of environmentally friendly active coke production line in Shenglong in China. The core index of active coke granules produced is also better than similar products in the market. The wear strength can reach more than 98%, the compressive strength can reach more than 50 kg, and the desulfurization value can reach more than 22 mg.

The TISCO industrial wastewater treatment system designed with "integrated technology of integrated advanced wastewater treatment process for Iron and steel enterprises" has stabilized the actual effluent water quality to the special discharge limit of water pollutants in iron and steel enterprises and the surface quasi-Class IV water quality standard, setting a new benchmark for ultra-low discharge of integrated wastewater treatment in iron and steel enterprises.

Construction of "One Belt, One Road" green steel service exploration

Since the "Belt and Road" initiative was put forward, China has undertaken more than 60 steel projects in countries related to the "Belt and Road", with the contract value reaching 3 billion US dollars. These technologies and products have not only won the contract orders of developed economies with the strongest product competitiveness, such as providing the first set of BF dry bag dust removal system and coal injection technology and equipment for PoSCO in South Korea, but also exporting technology and the most advanced standards for economic developing countries, such as providing the full process of steel turnkey projects for Indonesia and Vietnam. In the past 10 years, MCC has been taking the most advanced steel technology and products into the "Belt and Road" as its own responsibility, so as to lead the development of the steel industry in these countries directly into the first echelon of the world's steel development and achieve the purpose of green and sustainable development. All new steel projects in the "Belt and Road" countries adopt the highest domestic pollutant emission standards as the engineering guarantee value. In terms of energy consumption, it is first planned in accordance with the most advanced process, and it is recommended to choose the domestic and foreign advanced equipment with the lowest energy consumption and arrange it into the most compact production line, so that the energy consumption of the whole system can reach the first-class level of domestic steel enterprises. Due to long-term adherence to the implementation of green and low-carbon steel projects in the "Belt and Road", both domestic and foreign advanced standards as the basis, and domestic performance enterprises as a reference, so that MCC Group continues to provide continuous high-quality services for the "Belt and Road" steel projects.
