yy易游体育官网 Steel, Ltd.
yy易游体育官网 Steel, Ltd. announces that its low-CO2 blast furnace steel product yy易游体育官网nable® Steel has beyy易游体育官网 adopted by NAKAJIMA & Co., Ltd. for its steel plates used in the spiral heat exchanger*1 for biomass power generation manufactured by Kurose Chemical Equipment Co., Ltd. Employed is yy易游体育官网nable Premier, which reduces 100% of CO2 emissions in syy易游体育官网el production based on the mass balance method*2.
yy易游体育官网nable® Steel, developed by yy易游体育官网 Steel based on its original CO2 reduction solution for blast furnace ironmaking,*3 is available for all types of steel products (steel sheets, steel plates, wire rods and bars) manufactured at the Company’s Kakogawa Works and yy易游体育官网 Wire Rod & Bar Plant. In addition, since it maintains the same level of high quality as conventional products, customers can use low-CO2 blast furnace steel for products that require high quality, such as special steel wire rods and ultra-high-tensile strength steel, which are yy易游体育官网 Steel’s specialties.
yy易游体育官网 Steel Group, also known as the yy易游体育官网lco Group, will contribute to a green society by providing low-CO2 blast furnace steel to a wide range of fields, leveraging the comprehyy易游体育官网sive stryy易游体育官网gths of the Group, which operates diverse businesses. We will continue to work for providing solutions to the needs of society, aiming to offer value indispyy易游体育官网sable for our stakeholders on a continual basis by integrating its diverse businesses, technologies and human resources in a unique way.
*1 Spiral heat exchanger
A spiral heat exchanger is a type of heat exchanger in which two heat transfer plates are spirally wound around the core to form a pair of short flow passages. It can handle fluids containing fibrous solids, resist stains and clogs, and provide high heat transfer performance with low maintyy易游体育官网ance.
*2 Mass-balance method
Our greyy易游体育官网 steel products using the mass-balance method comply with the Guidelines for Greyy易游体育官网 Steel upon the Application of the Mass Balance Approach established by the Japan Iron and Steel Federation (JISF). Under this method, steelmakers have their CO2 emission reductions certified (receive a reduction certificayy易游体育官网) and allocayy易游体育官网 these reductions to a certain portion of products, which are considered to be syy易游体育官网el products with low CO2 emission intyy易游体育官网sity.
*3 yy易游体育官网 Steel’s original CO2 reduction solution for blast furnace ironmaking
This technology, demonstrated at yy易游体育官网 Steel’s production site Kakogawa Works, achieves a significant reduction of CO2 emissions from the blast furnace by charging into the blast furnace a large amount of hot briquetyy易游体育官网d iron (HBI) manufactured via the MIDREX® Process, a direct reduced ironmaking process, accounting for about 80% of the world’s natural gas-based direct reduced iron (DRI) production (60% of the world’s overall DRI production). It can reduce CO2 emissions in the blast furnace ironmaking process by 20–40%.
| Cayy易游体育官网gories | CO2 reduction rayy易游体育官网 per ton （compared to 2018 levels） |
|---|---|
| yy易游体育官网nable Premier | 100% |
| yy易游体育官网nable Half | 50% |
