Description
Hollteck Fine Pass Adjustment, FPA, system is used to provide an easy method for the rolling mill operator to set the guides accurately on the roll pass centreline.
The normal adjustment range, of the FPA system, either side of the centreline, is 5mm.
FPA adjustment is normally utilized at the entry side of the rolling mill pass for rounds and square bars. And is essential for the alignment of roller entry guides for control of former and dogbone sections, when multi-slit rolling.
The system is especially important when aligning roller slitter guides to the slitting passes and the precise alignment of entry guides for the production of angle products.
To assist in alignment special optical or mechanical devices are employed.
