Safety
PPE required when taking a fiber diameter sample
Leather gloves
Boots
Bump cap or hard hat
Long sleeves
Safety glasses
Double hearing protection
Applied to bolt prior to a spinner change
Anti-seize
What type of furnace will McGregor have?
Gas/Oxy
2 methods currently used to measure fiber di in KINA (2 different pieces of equipment)
Micronaire, fiber index machine
Tells you how many holes are being utilized on the spinner
Drop exit line
Double hearing protection is needed after how many decibels
100-105 dB
Reasons for a spinner change
Will accept any of the following:
Quality issues
EOL
Changing from batts to rolls
Area that lies directly after the Canal and is the final conditioning stage before the glass is formed into fibers. In this area, temperature control is extremely important to satisfy the fiber forming process.
Forehearth
Increasing main burner flow will do what to the fibers
Shorten them
In this setting the airlapper zone is 'off'
Dwell
Additional PPE needed for replacing a bushing
Safety harness
Why do we install a back up wrench or 'spud wrench' on top of the fiberizer?
To ensure spinner motor shaft does not turn on operator during change
______ is monitored and controlled to ensure that the excess combustion gasses are exhausted properly to prevent excess wear on the furnace.
Furnace pressure
Ratio set to allow for ignition during warm-up and sustained combustion during operation
Air/gas ratio or thermox
A device that controls the flow of glass from the forehearth
Should have on you while on the deck at all times in case of emergency
A RADIO
Name 3 types of spinners that we will have in McGregor
40 Row
46 Row
50 Row
Responsible for getting heat mixed into the lower depths of the melter by returning heat to the rear via convection and melting the batch logs from underneath.
Hot Spot
Creates potential problems to either the melter or the glass fiber properties
Ceramic or any type of contamination
Gives the operator an idea of parameters for each product code
Set point table
Why are rubber gloves required for some tasks on the deck?
Conductivity
Why is it important for the spinner to be hot when dropping glass?
To avoid loading spinner up
This process removes the carbon buildup from the burners. (This build-up forms on the end of the natural gas nozzle where the gas and oxygen meet).
Desooting
Do you want shorter or longer fibers when making rolls? WHY?
To avoid mat from tearing
How long it takes for the glass to leave your spinner? Checked before a spinner change
