IMPULSE - Advanced Industrial Manufacture of Next-Generation MARBN Steel for Cleaner Fossil Plant

ImPulse将使用一种新型的“MARBN”高温钢，该钢最近在TSB资助的项目“Impact”中开发，被证明能够将蒸汽发电厂的温度提高25摄氏度。ImPulse将把MARBN从实验室带到钢锭铸件、管件和焊接件的全面工业生产中。ImPulse将包括大多数Impact成员以及新的管道、焊接和创新研究合作伙伴。这将提高当前和未来钢基蒸汽发电厂的效率和可靠性，从而提高供应的安全性，减少成本和碳排放。将开发MARBN 8吨钢锭铸造技术，并在高温(至1250摄氏度)试验和制造模拟之后，进行两次全尺寸管材挤压试验，并通过测试和电子金相验证产品。还将开发、鉴定和测试匹配的焊接耗材。长期蠕变和蠕变-疲劳数据生成将用于性能验证、材料标准化和压力容器设计规范。与欧洲KMM-VIN合作的互动将使与平行欧洲项目的建设性交流成为可能。拉夫堡大学(LU)将利用其在表征以及热力学和动力学建模方面的强大背景，对MARBN在加工和焊接后的微观结构进行彻底调查，以便为制造路线和所需的热处理提供信息。此外，LU将彻底调查与现有电厂钢的蠕变性能有关的数据，以提供与MARBN的直接比较，以鼓励其在商业部门中使用。

IMPULSE will work with a novel "MARBN" high temperature steel, recently developed in the TSB funded project "IMPACT"and shown to offer capability for an increase in steam power plant temperature of 25 degrees C. IMPULSE, whoseconsortium includes most IMPACT members together with new pipe, welding and innovative research partners, will takeMARBN from the laboratory on to full-scale industrial manufacture of ingot castings, pipework, and weldments. This willimprove efficiency and reliability of current and future steel-based steam power plant, and thus increase security of supplyand reduce cost and carbon emissions.MARBN 8-tonne ingot casting technology will be developed, and following high temperature (to 1250 degrees C) testingand manufacturing simulation, two full-scale pipe extrusion trials will be undertaken, with product validation by testing andelectron metallography. Matching welding consumables will also be developed, qualified and tested.Long term creep and creep-fatigue data generation will feed into performance validation, materials standardisation, andpressure vessel design codes. Interaction with the European KMM-VIN collaboration will enable constructive interchangewith parallel European projects.Loughborough University (LU) will make use of its strong background in characterisation and thermodynamic and kineticmodelling to provide a thorough investigation of the microstructures of MARBN after processing and welding in order toinform manufacturing routes and required heat treatments. In addition, LU will thoroughly investigate data relating to the creep performance of existing power plant steels to provide a direct comparison to MARBN to encourage its use within thecommercial sector.
