Once a mill is aligned, rolls need to be installed. Two basic methods for putting rolls on a mill predominate. One is to put all the rolls on at once, and the other is to put one pass on at a time while adjusting and checking profiles along the way. Most rolls are designed with rims and hubs using a … See more
Tube life expectancy is dependent on material construction and how the tube is employed i.e. circuit type, operating parameters, thermal cycles, etc. You nailed it brf! I have seen the same brand and model tubes rated to last as little as 5k hours in one type and brand of gear and as long as 100k hours in another (6DJ8 btw).
