Improving flying cutoff operations, mill productivity

摘要

Making tube or pipe is anything but easy. During a typical shift, the mill operator has to keep an eye on a dozen variables and make scores of decisions to keep the mill running at maximum productivity. Most of the focus is on big-picture items like line speed and weld heat to make sure the line is running as fast as possible and inline inspection results to verify that the mill is making salable product. However, many details come into play too. How are the bearings holding up? Are the rolls still in good condition? Is the scarf bin filling up again? How long has it been since I changed the scarfing tool? Why is the cutoff saw making that noise?
