In 2013 approximately 110 Mt "waste" slag was produced worldwide at temperatures of 1650 oC containing ~25% of FeO,making it a potential source of energy and raw material. This work aims to combine and implement two concepts developedin the laboratory to industrial steelmaking. The first is to convert the thermal heat of the slag into hydrogen (from water),which can be used to lower the in-house C footprint or exported externally as a fuel. Secondly the valuable metal oxidesare recovered for in-house re-use and lower raw materials usage or exported for other purposes. Both concepts are basedon controlling the gas atmosphere. The project aims toat developing fundamental knowledge on the slag structure and itsevolution as function of gas atmosphere and temperature (WP1 and WP2) and based thereupon, design and build anindustrial test-reactor for carrying out the process (WP3). If implemented worldwide, it is envisaged that the process, ifsuccessful, could save over $3,300 M based on the BOS steel produced in 2013. In addition, the recovery of heat andvaluable chemicals contributes to a more green and energy and raw-material resilient steel industry.The Warwick group will lead on the development of the integrated heat-materials recovery process, completing scale-uptrials to recover both the thermal energy (producing syngas fuel) and valuable metal elements in oxide forms (e.g. Fe3O4and Fe2MnO4). They will also be involved in WP2 - providing support for materials recovery and WP3 - advice for the pilotplant trials.

2013年，全球约有1.1亿吨温度为1650 ℃的“废”渣，其中含有约25%的FeO，使其成为潜在的能源和原材料来源。本工作旨在将实验室提出的两个概念联合收割机应用于工业炼钢。第一种是将炉渣的热能转化为氢气（从水），可用于降低内部碳足迹或作为燃料出口到外部。其次，回收有价值的金属氧化物用于内部再利用和降低原材料使用量或出口用于其他目的。这两个概念都基于控制气体气氛。该项目旨在发展炉渣结构及其随气体气氛和温度变化的基础知识（WP 1和WP 2），并在此基础上设计和建造一个工业试验反应器以实施该过程（WP 3）。如果在全球范围内实施，预计该过程如果成功，可以根据2013年生产的BOS钢节省超过33亿美元。此外，热能和有价值的化学品的回收有助于实现更加绿色的能源和原材料弹性的钢铁工业。沃里克集团将领导开发综合热能-材料回收工艺，完成规模扩大试验，以回收热能（生产合成气燃料）和氧化物形式的有价值的金属元素（例如Fe 3 O 4和Fe 2 MnO 4）。他们还将参与WP 2-为材料回收提供支持和WP 3-为中试工厂试验提供建议。
