ArcelorMittal Dofasco - Automation of Slag Raking

ArcelorMittal Dofasco自1912年开始生产钢铁，是汉密尔顿最大的私营企业雇主，每年运送450万吨钢卷。在炼钢中，钢包冶金设备（LMF）完善了钢液的冶金，使其达到预期的最终用途，同时还去除了炼钢过程中的副产品——炉渣。液态钢是用直径约5米的大容器运到LMF的，容器中含有300多吨温度为1600摄氏度（°C）的钢，其中包括4吨炉渣。渣必须清除，因为它会对质量产生负面影响，包括过度氧化，它比钢液密度小，所以它停留在钢包的表面。为了清除矿渣，传统上操作人员可以直观地识别矿渣，并用2吨重的液压耙将其清除。为了有效地执行这一过程，需要一个经验丰富的操作员，手工灵巧和丰富的经验。展望未来，ArcelorMittal Dofasco将使用最精确的炉渣识别和耙取过程，以确保在每次炼钢过程中，在正确的时间清除正确数量的炉渣。这将确保渣不会留在钢包中，也不会从钢包中取出钢。为此，由Esteve Hassan博士领导的莫霍克学院应用研究小组将与Dofasco合作，测试图像技术，以识别炉渣，并将图像系统与耙控制集成，以实现自动除渣。传感器、电子设备、软件和工业物联网都将被用于自动化过程，允许操作员在过程中发挥监督作用。除渣精准、卫生、安全

ArcelorMittal Dofasco has been producing steel since 1912 and is Hamilton's largest private sector employer,shipping 4.5 million tons of steel coils annually.In steelmaking, the Ladle Metallurgy Facility (LMF) perfects the metallurgy of liquid steel for its intended enduse, while also removing slag, a by-product of the process. Liquid steel is brought to the LMF in a massiveladle that is approximately 5-metres in diameter and contains more than 300-tons of 1,600 degrees Celsius(°C) steel, including 4-tons of slag. The slag, which must be removed as it negatively affects quality,including over-oxidation, is less dense than the liquid steel so it rests on the surface in the ladle. To remove theslag, traditionally an operator visually identifies the slag and removes it with a 2-ton hydraulic rake. Toperform this effectively, the process requires an experienced operator, manual dexterity and significantexperience.Looking ahead, ArcelorMittal Dofasco will use the most precise slag identification and raking process possibleto ensure the correct amount of slag is removed at the right time during each heat of steel. This will ensure thatslag is not left in the ladle, nor is steel taken from the ladle. To do this, a Mohawk College applied researchteam led by Dr. Esteve Hassan will collaborate with Dofasco to test imagery technologies to identify the slagand to integrate the imagery system with the rake controls to automate the slag removal. Sensors, electronics,software and the Industrial Internet of Things will all be utilized to automate the process, allowing the operatorto take a supervisory role in the process. Slag removal will be precise, health and safety
