Can someone translate this text to such English I can understand?
thanks.
"The chief application of composite rolls in the rolling of steel
has been for work rolls in four-high hot and cold strip
mills and in plate mills; in the rolling of nonferrous metals,
the chief application has been for rolls for hot breakdown and
cold reduction of sheet and strip."

I'd gladly translate it if I understood the paragraph it myself.. perhaps
some knowledge of the steel industry would help..?

I'll give it a go:
>
> "The chief application
The main use
>of composite rolls
Don't know about composite - composed of several types of steel?
I think "rolls" refers to long strips of metal coiled up.
>in the rolling of steel
Rolling steel is to put a plate or strip of steel between pairs of rollers to
make it
thinner
> has been for work rolls
Work rolls are the raw material provided by a smelter to a manufacturer
>in four-high hot and cold strip mills
Four-high is maybe a mill that works four strips off rolls through rollers at
once
and in plate mills;
A mill that chops the strip from a roll into plates?
>in the rolling of nonferrous metals,
Nonferrous metals are like aluminum, brass, copper, etc. - anything without iron
> the chief application has been for rolls for hot breakdown and
No suggestions about hot breakdown
> cold reduction of sheet and strip."
I think cold reduction is making the metal thinner by pressure without heat.
No guarantees for accuracy(

The tiny little bit I know about steel I learn more than forty years
ago and even then it was presented to me in Czech, but I am pretty
sure Martin made several unfortunate guesses. He wrote:
>> "The chief application
>The main use
Not bad so far ;)!
>>of composite rolls
>Don't know about composite - composed of several types of steel?
>I think "rolls" refers to long strips of metal coiled up.
No. "Rolls" refers to shape forming rollers. As far as I remember,
composite rolls are basically rollers made from several layers,
usually hard cast iron on the surface, with a tough steel core.
>>in the rolling of steel
>Rolling steel is to put a plate or strip of steel between pairs of

This is quite correct. Except the final product does not have to be
flat: strips, sheets and plates. It could be other, more complex
profiles, rods, 'angles', 'I' beams, 'channels', etc, even tubes and
other hollow cross-sections.
>> has been for work rolls
>Work rolls are the raw material provided by a smelter to a

I do not think so. Work rolls are the shaping rollers, as against the
rolls that just guide the material or provide axillary pressure.
>>in four-high hot and cold strip mills
>Four-high is maybe a mill that works four strips off rolls through
>rollers at once
Mills with vertically stacked pairs of rollers for multiple passes of
material, back and forth.
>>and in plate mills;
>A mill that chops the strip from a roll into plates?
No. Over a certain thickness, sheets are simply called plates.
>>in the rolling of nonferrous metals,
>Nonferrous metals are like aluminum, brass, copper, etc. - anything
>without iron
Without _substantial_ amount of iron...
>>the chief application has been for rolls for hot breakdown and
>No suggestions about hot breakdown
Hot breakdown means the initial working, preliminary passes of ingots
- glowing hot chunks of metal.
>> cold reduction of sheet and strip."
>I think cold reduction is making the metal thinner by pressure
>without heat.
In general, heat is not applied during rolling operations themselves,
but the workpiece can sometimes be repeatedly re-heated. Cold
reduction is used to achieve superior surface finish, closer
tolerances and desired mechanical properties through cold working of
the metal.

thanks to all who replied. it's actually good to hear you don't quite
understand it either - i thought my english wasn't to good after i read
that. i have 8 pages of that to translate to slovene, can you believe that?
