The first phase will build an annual production capacity of 180,000 tons of BA precision stainless steel strips, and the second phase will build an annual production capacity of 40,000 tons of ultra-thin precision stainless steel plates and strips.
Huale stainless steel hot acid line annealing furnace project was successfully ignited
On the morning of February 18, the Huale stainless steel hot acid wire annealing furnace project, which was contracted and constructed by MCC Southern Thermal Engineering Co., Ltd., was successfully ignited and officially entered the oven stage. It is reported that this project is the first narrow-band stainless steel continuous solution annealing furnace project undertaken by MCC Southern Thermal Engineering Company, with a total furnace length of 210 meters and an annual designed production capacity of 500,000 tons. The main product is 200 series stainless steel.
Valin Xianggang Sintering Machine Environmental Protection and Technical Quality Improvement Project Put into Operation
On February 18, Valin Xianggang's sintering machine environmental protection and technological upgrading project was successfully put into operation. This project is another large-scale sintering project jointly constructed by Valin Xianggang and MCC Changtian after the No. 1 sintering machine and the new No. 2 sintering machine were completed and put into operation. The project adopts advanced technologies such as comprehensive sealing of sintering machine, intelligent frequency conversion control of main exhaust fan, and high-efficiency dust removal. After it is put into production, it will comprehensively drive and promote the improvement of Valin Xianggang's sintering process and competitiveness in energy saving and environmental protection, and contribute an important force to maintaining the industry leading edge of Valin Xianggang's sintering technology.
Fujian Longgang hot-rolled strip project started
On February 16, Fujian Longgang 1580 hot-rolled strip project started smoothly. After the completion of the project, the annual sales revenue will be about 5.3 billion yuan, which will drive the economic growth of related industries by more than 4 billion yuan, and arrange direct employment and drive more than 7,500 social employment personnel in related industries. It plays an important role in optimizing the spatial layout of the iron and steel industry in Fujian Province, improving the product structure, leading low-carbon green development, exploring the coordinated development of the industry, and implementing the national iron and steel enterprise structural adjustment and revitalization plan.
The hydrogen-based shaft furnace project of Baosteel Zhanjiang Iron and Steel Zero-Carbon Demonstration Plant started construction
On February 15, Baosteel Zhanjiang Iron and Steel Zero-Carbon Demonstration Plant's million-ton hydrogen-based shaft furnace project officially started. This project is the first one million-ton hydrogen-based shaft furnace in China, and also the first direct reduction production line integrating hydrogen and coke oven gas for industrial production. The total investment of the project is 1.89 billion yuan. It is expected to be completed by the end of 2023. After the project is put into operation, compared with the same scale of molten iron production of the traditional full-process blast furnace ironmaking process, it can reduce carbon dioxide emissions by more than 500,000 tons per year. It is of great significance to green the new ecology and promote regional clean energy optimization and economic development.
The No. 2 blast furnace of Meishan Iron and Steel started to tap iron
On February 15th, the No. 2 blast furnace of Meishan Iron and Steel was successfully ignited and started, and the utilization coefficient of the No. 2 blast furnace reached 2.62 on the 16th and 17th. Prior to this, all the staff of the iron smelting plant, in a full state of refueling and "quick drying", devoted themselves to various preparations before the No. 2 blast furnace was opened, laying the foundation for the smooth commissioning of the No. 2 blast furnace.
80,000 cubic meters blast furnace gas tank of Hegang Plug Steel was put into operation
At 10:00 a.m. local time on February 10, Serbia, the 80,000-cubic-meter blast furnace gas tank of Hegang Saigang was successfully bleed for one time, and it was officially put into operation. The commissioning of the project is the prelude to the full-scale production of Hegang Saigang's energy technical transformation project. Hegang Saigang realizes the instantaneous gas recovery caused by the unbalanced production, effectively buffering the frequent fluctuations that are difficult for gas users to adapt to. , realize the surplus to make up the debt, and reduce the energy waste caused by the emission. At the same time, using the gas tank to adjust the pressure of the gas pipe network will significantly improve the gas quality and stabilize the thermal power of the gas users. HBIS will write a wonderful Chinese story on the "Belt and Road".
