Raghu, Thank you very much for your reply
The mill under concern is a tandom type mill so there is continuous material rolling taking place each angle or channel produced is of a fixed length 18 - 50 feets. and there is discontinuous flow of material. I mean once a angle is rolled the next angle does not come out immediately following the earlier, there is a gap of a few second 4-5 seconds in between the product coming out.

Regards.
