Emissivity and IR Pyrometer selection

Hello vettecoupe,

No offense taken.

I would like to be more helpful and I will check the forums more often to see the topics and to share /or give some ideas.
At the bottom of that page you posted it's written that Land cyclops 153 and other Land pyrometers were replaced by the new model 100.

Best regards

Hello,

I recommend that you talk with the company that supplied the your continuous cast line and rolling mill.

I really loved the moderator's answer. At every question...call this... contact this.....

The exit temperature of the bar (I assume is a Hazlett caster) it should be around 990 and 1015 degree C. Don't forget to measure it at the top of the bar on the side you will have different reading.
I recommend entering the mill (SMS) with 860-880 degree C.I use a Land (Cyclops 153) hand held pyrometer with the emissivity 0.84.
For both measurements Caster exit and mill entry.

Hope this helped.

Hello tuburubu,

We quickly try to give people a place to do their own, up to the minute research as we do not have the time. Moreover we are not going to spend unknown hours of free calculations and research for technical people who often already have the answers and are just looking for a second source of supply or perhaps a second opinion. In addition, we often get misleading or incomplete information in the initial query.

This thread is a typical example.

The company in question recently purchased, installed and started a copper continuous cast line. My former company also has a Krupp-Hazelett continuous copper cast line for more than three decades and I know exactly what he wants. Why would we contact Hazlett to find out their present recommendation when the company who supplied their line is no doubt in almost daily contact with them and has the latest information they need right at their fingertips. We are also not going to get into a conflict with their supplier's latest recommendation.

Finally it is our experience that if we to do all the work gratis, we usually don't even get a thank you for it.

On the other hand, if we were to do nothing and just leave the question out there, hoping for an answer, it could takes months or even years to get that answer and that would be really terrible. Obviously the Forums would then cease to exist if that were to happen.

In this particular case it took some 9 weeks to get an answer from you. While we all appreciate your answer, do you think the initiator of the thread waited on pins and needles for 9 weeks for your posting? I very much doubt it. We also don't know who you are but we do know what company you are with and where you are located. You could be a Nobel Prize winning metallurgist and the world's foremost authority on continuously casting metals but here nobody knows that. We don't even know if the information you provided is actually up to date but it is still good information to know and we thank you for it.

WE are certainly not criticizing you but rather trying to get you to see this from the other side of the Forums. We also look forward to you actively posting technical information in future. I am sure you have a lot of valuable information that can benefit all of us.

Sincerely,

Hello,
I enjoy the forums and the opportunities to exchange ideas and opinions related to manufacturing wire. I spent a lot of years selling equipment. One of the things that you do is respond to request for proposals. Eventually you learn what may be a potential sale or what is just someone looking for free engineering services. We used to get request for complete turn key magnet wire plants and initially we provided all of the necessary details. Eventually we learned that there were engineers and managers out there that were more than willing to let someone else do their thinking and their work with no real intention of purchasing anything.

This forum has participants that are sometimes like that. It is so much easier to research information today than it has ever been. It is disingenuous for some one to think or try to get all of their questions and problems solved in this discussion are. You can get a lot of good information and suggestions. Like Peter said the formus seldom if ever gets a thanks but more importantly seldom does someone come back and say "I tried the following and it did not work or it did work."

when there are good discussions and suggestions, it is equally important for feedback.

suggesting or recommending a place to find an answer is an answer. It just means the a little bit of the work has been left for you to do.

And what is wrong with that?

Hello vettecoupe

Thank you for your answer.

The company you are talking purchased, installed but didn't start yet. My last informations were that they will start in November this year.

I agree that nobody will thank you if you work gratis but for sure they will hate you if you charge them with a lot of money for every information. As you know too, technical persons are looking for different solutions and different approaches. The pour guy is looking for a hand held IR pyrometer and probably the caster supplier can give him one but for a huge price because he is buying it too from the same company.I've done Contirod line start up and I know how it is working. Keep the costs low and don't upset the supplier(even if the supplier is SMS and Hazelett is just a subcontractor).

My opinion is that this informations is harmful and they can be shared. This would be the real purpose of the forum no?

On the other hand I'm not a Nobel Prize winner metallurgist I just have some experience with the Contirod lines.

My location is less important since I'm moving all around Europe and "you don't know what company I'm with and where I'm located" (It really sounded like a threat.)

Best regards
