Background:In terms of global energy demand, according to the international energy authority, of the heating component 66% is industrial heat. This represents a staggering 20% of total demand. All of these processes utilise refractory [1] materials to contain and manage that heat. Steelmaking is no different. In fact, an integrated steel plant produces enough waste heat in a year to heat 500,000 homes. As such, to achieve net zero and solve the current energy crisis we must enhance industrial thermal efficiency through revolutionary approaches to the design and use of these refractory insulation materials. This is the primary goal and impact of this project.As TATA Steel moves towards its ambition of carbon neutral steelmaking by 2050 and a reduction of CO2 emissions of 30% in the UK by 2030[2], there is a need to transform the way sustainable steel is produced. Liquid Iron & Steel are both transported and processed in refractory coated vessels, examples being torpedoes, ladles, BOS (Basic Oxygen Steelmaking) vessels, tundishes, etc. At each process step, temperature loss occurs. The temperature deficit is addressed either through chemical heating processes, or adjustments made to scrap and alloy inputs to manage the final temperature. All of these steps increase energy requirements, have a resultant impact on the CO2 emissions and overall conversion cost of the final steel product; single degree changes across the operation can save hundreds of thousands of pounds per year.Project aims:The aim of the project is to study the Refractory coating systems, to both assess and reduce the energy losses and CO2 emissions of the steelmaking process. This will involve benchmarking, design studies, data analytics, thermal / finite element modelling, laboratory & plant scale trials and development of measurement systems (both contact & non-contact). It will also involve advanced refractory testing and collaboration with industrial, plant and research institutions will be required as it may provide wider opportunities to share learnings for the benefit of the global steel industry.[1] Refractory materials are designed to be resistant to decomposition by heat, pressure and chemicals, and to retain their mechanical properties at temperatures encountered in the modern manufacturing environment. The purpose of a refractory material is to contain heat whilst simultaneously protecting processing equipment. Typically, these materials are used as coatings for boilers, furnaces, incinerators etc and have multiple applications in the steel making process.[2] Tata Steel in Europe Sustainability Report 2019/2020 (https://www.tatasteeleurope.com/sustainability and https://www.tatasteeleurope.com/sites/default/files/TSE%20Sustainability%20report%202019-20%20%28EN%29.pdf)

背景：根据国际能源管理局的说法，供暖部件的66％是工业热量。这是总需求的惊人20％。所有这些过程都利用难治性[1]材料来控制和管理该热量。炼钢也没有什么不同。实际上，一年中综合的钢铁厂产生足够的废热，以加热500,000户房屋。因此，为了达到零净并解决当前的能源危机，我们必须通过革命性的设计和使用这些难治性绝缘材料来提高工业热效率。这是该项目的主要目标和影响。由于塔塔钢（Tata Steel）到2050年朝着碳中性钢制造的野心发展，到2030年英国的二氧化碳排放量减少了30％[2]，需要改变可持续钢的生产方式。液铁和钢既可以在难治性的涂层容器中运输和加工，例如鱼雷，载糖，BOS（基本的氧气制造）容器，脱落等。在每个过程步骤中，都会发生温度损失。温度赤字是通过化学加热过程解决的，或者对废料和合金投入进行调整以管理最终温度。所有这些步骤增加了能源需求，对最终钢产品的二氧化碳排放和总体转换成本产生了影响；整个操作的单度变化可以节省每年数十万英镑。项目的目的：该项目的目的是研究难治性涂料系统，以评估和减少钢制过程的能源损失和二氧化碳排放。这将涉及基准测试，设计研究，数据分析，热 /有限元建模，实验室和植物规模试验以及测量系统的开发（均与非接触式）的开发。它还将涉及与工业，工厂和研究机构的高级难治性测试和合作，因为它可能会为全球钢铁行业的利益提供更广泛的机会。[1]耐火材料旨在通过热，压力和化学物质对分解，并在现代制造环境中遇到的温度下保留其机械性能。难治材料的目的是含有同时保护加工设备的热量。通常，这些材料用作锅炉，炉子，焚化炉等的涂料，并在钢制过程中有多个应用。[2]欧洲塔塔钢2019/2020（https://www.tatasteelelope.com/sustainability and https://www.tatasteelepope.com/sites/sites/sites/defeault/files/files/files/tse%20sustainability%20sustainability%20Report%20Report%20Report%202019-2019-2019-202019-2028ENEM%28enen;
