在目前欧洲能源价格上涨以及CO2排放税成本高企的背景下,提高能源利用效率和降低CO2排放量已日趋重要。基于上述目标,奥镁公司可提供一系列多样化解决方案,包括使用优质耐材内衬、优化内衬维护以及改进工艺等。用多个实例论证了在炼钢过程中,智能耐材方案对于提高能源利用效率和减少CO2排放所起的作用。在电炉和转炉炉底使用含底吹气系统的一体化耐材产品,能加强熔池搅拌和加快冶金反应,从而改善多项生产参数,包括电耗、处理周期、电弧稳定性以及加快脱碳反应速率。毫无疑问,对于能量和质量转换效率、成本和CO2排放等多方面都有着重要意义。经过计算流体动力学(CFD)优化的电炉和转炉出钢系统,是改善能源效率管理的另一个耐材解决方案实例。利用这些先进的系统,不但缩短了出钢时间,同时节约了能源损耗以及提高了产能。另外,还有一种节约能源的有效方式是优化钢包衬和使用耐材内衬包盖,可减少热损失,降低转炉或电炉的出钢温度,同时降低LF炉中能量输入或化学反应热的需求。近期,奥镁公司新研发出一种中间包工作内衬(即自硬性喷涂料)。由于省去了像普通中间包工作内衬的烘烤过程,从而相应减少了CO2排放。综述了各种耐火材料产品的特点,并重点讲述了它们在节能和CO2减排等方面的应用效果。
In the current context of the rise in energy prices in Europe and the high CO2 emission tax costs, it is increasingly important to increase energy efficiency and reduce CO2 emissions. With these goals in mind, Alastair offers a wide range of solutions, including the use of premium refractory linings, optimized liner maintenance, and improved processes. A number of examples demonstrate the role of smart refractories in improving energy efficiency and reducing CO2 emissions during steelmaking. The use of integrated refractories with a bottom blown gas system in the electric furnace and converter hearth enhances bath mixing and accelerates metallurgical reactions to improve a wide range of production parameters including power consumption, process life, arc stability, and accelerated decarburization reaction speed. There is no doubt that this is important for many aspects of energy and quality conversion efficiency, costs and CO2 emissions. Computational fluid dynamics (CFD) optimized furnace and converter tapping systems are another example of refractory solutions that improve energy efficiency management. With these advanced systems, not only the tapping time is shortened, but also the energy consumption is saved and the production capacity is increased. Another effective way to conserve energy is to optimize ladle linings and use refractory linings to reduce heat loss, reduce the tapping temperature of the converter or furnace, and reduce the need for energy input or chemical reaction heat in the LF furnace . Recently, Austrian magnesium company newly developed a tundish lining (that is, self-hardening spray paint). As a result of eliminating the baking process like ordinary tundish work lining, thus reducing CO2 emissions. The characteristics of various refractories products are summarized, and their application effects on energy saving and CO2 emission reduction are mainly described.
