With the deepening of the green manufacturing concept, GB QU70 crane rail is gradually realizing environmental protection upgrades in production and application. In the manufacturing process, the electric arc furnace short-process steelmaking process is adopted, which can reduce carbon emissions by 30% compared with traditional blast furnace steelmaking, and the slag recycling rate reaches more than 98%. Through hot charging and hot delivery technology, the billet temperature into the furnace is kept above 600℃, which significantly reduces energy consumption and reduces the comprehensive energy consumption of each ton of rail production to 380kg standard coal.
From the perspective of the entire life cycle, the sustainable development advantages of QU70 rails are obvious: it can be 100% recycled, and the performance of recycled rails can reach 95% of new rails; by optimizing logistics solutions, carbon emissions in the transportation link are reduced by 25%; with the digital management system, precise maintenance is achieved, and the material utilization rate is increased by 40%. These practices not only meet increasingly stringent environmental protection requirements, but also create significant green economic benefits for users.
