ArcelorMittal Dofasco - Automation of Slag Raking

安赛乐米塔尔多法斯科自1912年以来一直生产钢铁，是汉密尔顿最大的私营部门雇主， 每年运输450万吨钢卷。 在炼钢过程中，钢包冶金设备（LMF）完善了钢水的冶金，以达到预期目的 使用该方法的副产品，同时也除去炉渣。液态钢以巨大的 一个直径约5米，装有300多吨1,600摄氏度的铁水包 （°C）钢，包括4吨矿渣。必须去除炉渣，因为它会对质量产生负面影响， 包括过氧化，比液态钢密度小，因此它停留在钢包的表面上。以除去 渣，传统上操作员目视识别渣并用2吨液压耙将其清除。到 有效地执行这一过程，需要一个有经验的操作员，手工灵巧和显著 体验. 展望未来，ArcelorMittal Dofasco将尽可能使用最精确的炉渣识别和耙除工艺 以确保在每炉钢的过程中在正确的时间去除正确量的炉渣。这将确保 渣不会留在钢包中，钢也不会从钢包中取出。为此，莫霍克学院的一项应用研究 由Esteve哈桑博士领导的一个小组将与Dofasco合作，测试图像技术，以识别炉渣 并将成像系统与耙控制器集成以使炉渣去除自动化。传感器，电子设备， 软件和工业物联网都将用于自动化过程，允许操作员 在这个过程中发挥监督作用。除渣将精准、健康、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 end use, while also removing slag, a by-product of the process. Liquid steel is brought to the LMF in a massive ladle 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 the slag, traditionally an operator visually identifies the slag and removes it with a 2-ton hydraulic rake. To perform this effectively, the process requires an experienced operator, manual dexterity and significant experience. Looking ahead, ArcelorMittal Dofasco will use the most precise slag identification and raking process possible to ensure the correct amount of slag is removed at the right time during each heat of steel. This will ensure that slag is not left in the ladle, nor is steel taken from the ladle. To do this, a Mohawk College applied research team led by Dr. Esteve Hassan will collaborate with Dofasco to test imagery technologies to identify the slag and 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 operator to take a supervisory role in the process. Slag removal will be precise, health and safety
