SUMMSEED启动开发用于采矿的中锰钢，采用铸造与激光线材DED技术

In a significant step forward for sustainable heavy industry, the new European project SUMMSEED has officially launched. Funded by the Research Fund for Coal and Steel, this initiative aims to develop advanced medium manganese steels specifically designed for mining and heavy machinery applications. By combining traditional industrial casting with cutting-edge laser-wire directed energy deposition (DED), the project promises to deliver materials that are both tougher and more environmentally friendly.

在可持续重工业领域迈出的重要一步中，新的欧洲项目SUMMSEED已正式启动。该项目由煤炭与钢铁研究基金资助，旨在开发专门用于采矿和重型机械应用的先进中锰钢。通过将传统工业铸造与尖端激光线定向能量沉积（DED）技术相结合，该项目有望生产出既更坚韧又更环保的材料。

The mining and heavy machinery sectors have long sought steels that reduce environmental impact without sacrificing performance. SUMMSEED addresses this by focusing on medium-Mn (manganese) steels that are tailored for both industrial casting and remanufacturing through additive manufacturing. The goal is to create alloys that offer comparable or superior strength, toughness, and wear resistance to traditional materials like Hadfield steels, while using fewer critical alloying elements.

采矿和重型机械行业长期以来一直寻求既能减少环境影响又不牺牲性能的钢材。SUMMSEED通过专注于中锰（Mn）钢来解决这一问题，这些钢材专为工业铸造和通过增材制造进行再制造而设计。目标是制造出与传统材料（如哈德菲尔德钢）相比具有相当或更优强度、韧性和耐磨性的合金，同时使用更少的临界合金元素。

Coordinated by the Technical University of Catalonia (UPC) in Spain, the consortium includes key industry players such as Sandvik (mining products), Sidenor (steel production), and Meltio (metal 3D printing systems). Academic partners like Delft University of Technology and TU Bergakademie Freiberg contribute research expertise, while CIM UPC supports industrial validation.

该项目由西班牙加泰罗尼亚理工大学（UPC）协调，联盟包括山特维克（采矿产品）、Sidenor（钢材生产）和Meltio（金属3D打印系统）等关键行业参与者。代尔夫特理工大学和弗莱贝格工业大学等学术合作伙伴提供研究专业知识，而CIM UPC则支持工业验证。

The project workflow begins with alloy design and laboratory testing, moves to pilot plant casting trials, and culminates in the repair of real cone crusher components—parts critical to mining operations. This circular approach supports the reuse of end-of-life parts, keeping high-value components in service longer and reducing material waste.

项目工作流程从合金设计和实验室测试开始，然后进入中试工厂铸造试验，最终实现对真实圆锥破碎机部件——采矿作业中的关键部件——的修复。这种循环方法支持报废部件的再利用，使高价值部件保持更长的使用寿命，并减少材料浪费。

SUMMSEED’s focus on near-net-shape techniques, including laser-wire DED, allows for precise material deposition and repair. This reduces the need for full part replacement, cutting both costs and carbon emissions. As project coordinator Pere Barriobero Vila from UPC explains, “By tailoring alloys for both casting and directed energy deposition remanufacturing, the project aims to replace traditional Hadfield steels with leaner, more cost-efficient grades that offer high strength, toughness and wear resistance while reducing CO₂ emissions and the use of critical raw materials.”

SUMMSEED专注于近净成形技术，包括激光线DED，可实现精确的材料沉积和修复。这减少了对完全更换部件的需求，从而降低了成本和碳排放。正如项目协调员、UPC的Pere Barriobero Vila所解释的那样：“通过为铸造和定向能量沉积再制造定制合金，该项目旨在用更精简、更具成本效益的牌号替代传统的哈德菲尔德钢，这些牌号具有高强度、高韧性和耐磨性，同时减少CO₂排放和关键原材料的使用。”

To ensure industrial readiness, the validation phase includes microstructural and mechanical testing, advanced laboratory analysis, and in situ synchrotron characterization. Partners like Sandvik will lead demonstrator development and test upscaling, while Meltio provides the DED equipment and remanufacturing expertise. The project will also produce processing guidelines and workshops to support widespread industrial adoption, and inform policymakers on lower-emission, circular steel production.

为确保工业就绪性，验证阶段包括微观结构和力学测试、高级实验室分析以及原位同步辐射表征。山特维克等合作伙伴将领导演示器开发和测试放大，而Meltio则提供DED设备和再制造专业知识。该项目还将制定加工指南并举办研讨会，以支持广泛的工业应用，并为政策制定者提供关于低碳、循环钢材生产的信息。

For those interested in exploring advanced materials for their own projects, the principles behind SUMMSEED—combining traditional manufacturing with additive techniques—are also reflected in the growing availability of high-quality 3D printing models and premium STL files for industrial and hobbyist use alike.

对于那些有兴趣为自己的项目探索先进材料的人而言，SUMMSEED背后的原则——将传统制造与增材技术相结合——也体现在日益普及的高质量3D打印模型和高级STL文件中，这些模型和文件同时适用于工业爱好者和业余爱好者。

Beyond SUMMSEED, the broader additive manufacturing landscape faces material and qualification challenges. In Australia, a QDSA-funded effort led by Charles Darwin University, in partnership with James Cook University, the Australian Institute of Marine Science, and SPEE3D, is exploring new ways to qualify materials for demanding environments. These parallel efforts highlight the global push toward more sustainable, high-performance manufacturing.

除了SUMMSEED之外，更广泛的增材制造领域面临材料和认证挑战。在澳大利亚，由查尔斯·达尔文大学领导、詹姆斯·库克大学、澳大利亚海洋科学研究所和SPEE3D参与的一项QDSA资助项目，正在探索在苛刻环境中认证材料的新方法。这些平行努力凸显了全球范围内推动更可持续、更环保制造的趋势。

SUMMSEED represents a first step toward transferring medium-Mn steel metallurgy to industrially relevant conditions. By integrating casting and laser-wire DED, the project offers a complete circular process that extends component lifespan, minimizes material waste, and reduces environmental impact—key priorities for the future of heavy industry.
