IMIS (Integrated
Manufacturing Information
System)
Computer system used to record production information.
Impact Tests
Tests to determine the energy absorbed in fracturing a test specimen
at high velocity. There are various kinds of impact tests, such as
charpy, izod, drop weight, etc.
Inclusions
Refers to a defect when particles of nonmetallic impurities, usually
oxides, sulfides, silicates, and such, which are mechanically held in
steel during solidification.
Integrated Steel Producer
A
steel company which manufactures solid steel products; starts with raw
materials such as iron ore, flux, etc, to make molten iron; converts
the molten iron to liquid steel in the steelmaking furnaces and
processes liquid to solid steel products. See Minimill Steel Producer.
Inter-Chemical Gauge
Wet film thickness can also be measured using an Inter-chemical Gauge.
A graduated circular cam is rolled against the plate between two
parallel rollers. The wet film thickness is then read directly on cam
at demarcation of coating wetting the cam. |

Intermediate Temper
A cold rolled hardness range specified with a 15-point Rockwell B
spread. See Quarter Hard Temper and Half-Hard Temper.
Internal Cleanliness
Measure of number and types of non-metallic inclusions such as oxides,
sulfides or silicates.
IPM Number (In-Process
Material)
A seven-character number, consisting of the unit ID and sequential
production number, used to track production history of a coil. The
letter and first digit are used to identify the production unit and
the last five digits are the sequential production identifying number.
IPM
An identifiable piece of steel; can be a slab, coil, or a bundle of
sheets, or several slit mults banded together.
Iron-Zinc
Alloy Coating
See Galvanized.
ISO Codes
The codes that designate the amount of contamination in the oil.
Isolate (Isolation)
To remove a boiler, or any particular part or system of a boiler, form
service by closing the manual valves. |
