load cells!
are essential parts for a troublefree casting operation. if they fail, we may either dump a lot slag into tundish (if slag entry is not detected automatically/manually).
there are times when auto tundish regulation failed and led to ladle closures because of improper seating of tundish on loadcells.
generally there are four load cells placed on the all four corners of a tundish. they must be perfectly levelled so that whenever a tundish is placed on the tundish car, the entire load of the tundish must be equally distributed on to those 4 load cells, each taking 1/4th of the entire tundish load.
if the levelling is not proper, tundish may not sit properly leading to fluctuations and hence troubled casting experience.
here are some pics of load cells in a tundish car. similar load cells are fixed in ladle turret arms too but with a little higher ratings.
sometimes improper loadcell placement may give huge errors that the shown tundish weight may be much lower than it actually is. sometimes we may end up discarding a lot of metal as tundish skull.
this above pic shows a tundish skull. has a lot of hot steel that shines in bright yellow. the brown covering on the tundish is the spray/working lining of which is made of roughly 70% MgO and 20% Silica.
