Billet

W = ρlwh. (ρ = rho = density)

Thanks,

i would like to know more about hot rolling mills.

1.What is the Mill speed?

2.How to select Reduction cum Pinion Gear according to mill stand speed?

Expecting ur expert reply

1. I don't know, never having worked in one, but I imagine the speeds could vary quite a lot depending on the metals, alloys, and sizes being milled.

2. Gear, pulley, and sprocket ratios are all simple arithmetic, mostly multiplication and division.

Mill speeds vary with the section of the material being rolled.

Look up Cogging, roughing and finishing mills or "stands" as they are known.

yes.

if for angle bar production 40*40*5 rolls over roughing & inter,mediate and coming to four finishing stands c1,c2,c3,c4.

What will be the mill speed of individual stands.

If Billet of size 110*110*1320(Length) mm rolls

The speed will depend on the waisting (necking) of the material. As the material passes through the stand it's internal temperature will rise, this determines the speed. The more the material is waisted the higher the temperature therefore multiple passes are used to keep the temperature under control. High-pressure water sprays on the output side help to break off scale and stop it being rolled back in to the material and not as many peoples think cool the roll stands.

Thanks.

if possible pls forward to me the rbasic rolling mill terminology notes also main components of 16" Rolling mill

I no longer have my text books on steel technology so I'm afraid your going to have to do some reading on tour own.

Google making shaping and treating of steel.

A quick way to get the final speed is to calculate the ratio of final length times original length of billet, then multiply times initial speed of billet in the first stands. If that is really what you want.

If what you want is just tons per hour its weight of billets per hour times number of billets rolled.

I now think he wants someone to do his homework!

The language thing always makes me give the benefit of the doubt. But as this has developed, i think you may be correct.

What type of billets are you working with?
