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

ArcelorMittal Dofasco自1912年以来一直在生产钢铁，是汉密尔顿最大的私营部门雇主，每年运送450万吨钢卷。在炼钢方面，钢包冶金设施（LMF）完善了钢水的冶金，以满足其预期的最终用途，同时还去除了过程中的副产品炉渣。液态钢被装在直径约5米、装有300多吨1,600摄氏度（°C）钢（包括4吨炉渣）的漏斗中送入LMF。由于炉渣对质量产生负面影响，包括过度氧化，因此必须将其去除，炉渣的密度低于钢水，因此它停留在钢包的表面上。为了清除炉渣，传统上，操作员目视识别炉渣，并用2吨的液压耙将其清除。为了有效地实现这一点，该工艺需要一名经验丰富的操作员、熟练的手工操作和丰富的经验。展望未来，ArcelorMittal Dofasco将尽可能使用最精确的炉渣识别和清渣工艺，以确保在每炉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里，钢也不会从钢包中取出。为此，由Esteve哈桑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相结合，以自动清除炉渣。传感器、电子设备、软件和工业物联网都将被用来实现这一过程的自动化，使操作员能够在这一过程中发挥监督作用。除渣将精准、健康、安全
