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.

在塔尔博特港，我们在炼铁和炼钢过程中花费了相当多的时间、精力和成本来生产和保持特定温度窗口内的液态金属，直到需要将其浇铸成固体产品。作为炼钢过程中能源和排放最密集的领域，任何低效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。在高炉浇铸(铁水)和将钢水浇铸成板坯之间，我们有几个工艺步骤，以及从各种设施和工厂运输所述铁水。按年计算，温度每下降一个度，就会产生额外的加热要求，这会对财务产生影响(每度80,000 GB)，并导致使用额外的材料和燃料来重新加热液态金属。在这些恶劣的环境中测量温度是具有挑战性的，因此有机会开发更先进和更强大的测温法，以实现更多的过程洞察，同时避免额外的材料使用，从而避免增加二氧化碳排放。在过程中，温度的测量在很大程度上是对大量材料的点测量，例如，使用手持红外温度计测量250吨‘鱼雷’(铁路运输容器)的铁水。已经尝试确定过程中不同阶段的温度，我们已经试验了一些商业上可获得的磷光涂料，但存在知识差距，人们认为这是一种特别有成效的研究途径，特别是与我们选定的合作者。
