Rolling Mill

Drop the cryptic style and sharpen your point

Hi wire,

Well put and good advice! IIS (It is simply) the WPQ (worst phrased question) I have seen FALT (for a long time)! Is it a person or a computer asking? Me wonders?

A little less 'pomp' and more circumstance perhaps?

Take care..................

Salim,

You would get better answers if you made your question clearer, and gave more information, such as:

1. I assume you're interested in a steel manufacturing mill. What is the process for this rolling mill are you talking about? Hot-, or cold-reduction?

2. What material is being rolled? What is its density?

3. What line speeds are involved, for every gauge of material being processed?

Etc., etc.

So many experts and engineers are here ready to answer you, but won't be able to, unless you ask the right question.

Hi langyaw:

very good advice there. It is a terrible way for the OP to start a thread and expect to get any help!

Take care..................

Dear Langyam

I want to know how the AGC internal configured for calculation of Tension & Speed varation as the feedback from the gauge to AGC.

This AGC is controlling with in bulit progam have integration , Differetial ,proprotation done. This AGC work work both type rolling mills . ACG ( automatic gauge correction ) on the feedback only

This AGC will give the correction to PLC and PLC give to the Drives and finally motor

Hi Salim,

Sounds like you're trying to implement Level 1 automation.

There is really no need for you to "reinvent the wheel", so to speak, or crack your head doing something somebody can do better and faster. Neither is it good trying to obtain a solution in a forum from people you haven't met, much less known personally. Like someone said in another thread, "I wouldn't design a safety sling from the info in these forums".

Besides, your question really needs more detail than what you've described.

So if I were in your place, I'd issue a request for proposal to my known AGC vendors. Before doing that, do some research from other steel mills, especially those who've implemented process control automation in all levels, and who are producing more or less the same products you're producing. (I know, this may smell like espionage, but a consultant can do the dirty job for you.) Take special note of the brands and specifications of their process control equipment, because these are the manufacturers you will be contacting for their proposals.

Once you have them, get a team to narrow down your choice to the top 2, and present them to higher management for final approval and procurement.

Make sure their scope includes commissioning, an acceptable test run volume, with a good warranty period, and reliable after-sales service.

Nevertheless, here are some sources for what you're looking for:

This mean you may not clear about my Q. Automation company will only reply those companies are in the filed of manufacturing, other automation can reply. Those company also will not tell directly

It is better for you to bring your question here: http://www.ia-community.com/forums/index.php?showforum=10

But be warned, they'll need more information about your problem, more than what you've given in this forum, otherwise, you'll still get no help.

Thank you had give web for IA
