Improved through process temperature control as a driver for decarbonisation

在塔尔博特港，我们在钢铁生产过程中花费了大量的时间、精力和成本，以生产和保持液态金属在特定的温度范围内，直到需要将其铸造成固体产品。作为炼钢过程中能源和排放最密集的领域，任何效率低下或计划外损失都会导致额外的成本和排放，这是可以避免的。在高炉铸造之间（铁水）将钢水浇铸成板坯的过程有几个工艺步骤，以及从不同的设备和工厂运输所述铁水。a additional额外heating加热requirement要求which哪一个is financial财政impactful影响（80英镑，000每度）在这些恶劣的环境中测量温度是一项挑战，因此有机会开发更先进和更强大的测温技术，以实现更多的工艺洞察，并避免使用额外的材料，从而增加CO2在该过程中存在温度测量主要是针对大量材料的点测量的领域，例如，用手持IR温度计测量250吨的铁水“鱼雷”（铁路运输船）。已经尝试确定温度在不同阶段的过程中，我们已经实验了一些商业上可用的磷光涂料，但有一个知识差距，它被认为是一个特别富有成效的研究途径，特别是与我们选择的合作者.

At Port Talbot we spend considerable time, effort and cost during our iron and steelmaking processes toproduce and maintain liquid metal within specific temperature windows until such time as it is required tobe cast into solid product. As the most energy and emissions intensive area within the steel makingprocess any inefficiencies or unplanned losses result in additional cost and emissions which could beavoided.As an example, between casting at the blast furnaces (molten iron) and casting the molten steel into slabwe have several process steps as well as transport of said hot metal from various facilities and plants.On an annualised basis every degree of temperature lost results in an additional heating requirementwhich is financially impactful (£80,000 per degree) and results in additional materials and fuels beingused to reheat the liquid metal.The measurement of temperature within these hostile environments is challenging and as such there areopportunities to develop more advanced and robust thermometry to enable more process insight as wellas enabling avoidance of additional material usage leading to increased CO2 emissions.There are areas within the process whereby the measurement of temperature is largely a pointmeasurement for a significant bulk of material e.g. a 250 tonne 'torpedo' (rail transport vessel) of molteniron is measured with a handheld IR thermometer. Attempts have been made to ascertain temperatureat various stages within the process and we have experimented with some commercially availablephosphorescent paints however there is a knowledge gap and it is felt this is a particularly fruitful avenueof research particularly with our chosen collaborators.
