Tests electrical circuitry and measures temperature and depth
level of materials in aluminum reduction pots: Places contact
rods of voltmeter against anode of reduction pot and agaisnt
lining (cathode) of next pot on line to obtain voltage reading
of pot circuit. Records meter reading, repeats test on next pot,
and deducts reading from previous raeding to determine any power
loss. Repeats test on each succeeding pot to obtain and record
power loss at each point along potline.
Removes concrete
sections of floor, using overhead hoist, to expose electrical
circuits. Places prongs of millivoltmeter on ground and
electrical connections to measure amount of positive and
negative charges entering pot.
Inspects electrical connections,
firebrick lining, and wriing to detect damaged, worn, or broken
parts, and notifies Pot-Room Supervisor (smelt. & refin.) of
discrepancies.
Breaks hole in pot crust with crowbar, and
inserts thermocouple to measure tmeperature of contents.
Measures depth of contents, using measuring rod, and records
temperature and depth on control form. Dips ladle into pot to
remove sample of aluminum for laboratory analysis, and pours
sample into mold. Records test readings, voltage loss,
temperatures, and detph levels on master control form, and
