Now we can reduce 40 points thk inspection period from every rolls to 3 times a day as samping as run without process change or with continuous run.
Let's say collect the 40 points thickness data at 8am, 4pm, and 12am (mid night), and the 1st roll after restart machine from die cleaning, chill roll cleaning, or resolve the process issues.
But, keep monitor the blending variation by load the weighing data and analyze. I can see variation between FB and Exxon that will appear on the top and botom sides and concern to carbon black property.
Tomorrow please resend blending data of 21 May again and review what actions have been taken today.
