Scanning of very hot surfaces. Advice needed.
Hi, i am looking for a 3d laser scanner that could scan the inside surface of a steel ladle. That's needed to create a 3d map and estimate the condition of the ladle lining.
I struggle to figure out what scanner can perform the job (consider we have all required heat/dust protection) done taking into account the the inner surface temperature can be as high as 1500-1600c... I know that not all lasers/scanners can do that job.
Thanks in advance!

Re: Scanning of very hot surfaces. Advice needed.
Dear Sergey,
There was a company that used early Riegl scanners for this purpose. They have used an active cooling system as you can imagine.
From what I remember they always plenty of them on stock since the ladle regularly spits out liquid steel...
A former employee of the company is still in the laser scanning business. I'll ask him if I can forward his email address to you.
All the best
Daniel

Re: Scanning of very hot surfaces. Advice needed.
Depends on the accuracy you need, I think this might be something you could scan threw a protective window/shield. There would be refraction but you should be able to keep 1cm accuracy (debatable here). There is also a thermal protection faro makes but I don't know if it is better than other scanners protection.

Obviously you would need the steel ladle to be sideways and scan at a distance. This is the type of projects I would most likely say no to, I had scanners break from heat in the past.

Re: Scanning of very hot surfaces. Advice needed.
Dear Leandre,
the reason why they used long range scanners for rather short range purposes was that the radiometric contrast atop a glowing surface is pretty poor. Hence, they've used somehing with a bit more juice.
The surface of interest is actually the brick cladding inside the laddle.

Re: Scanning of very hot surfaces. Advice needed.
Hi Daniel, Hi Leandre thanks a lot for your prompt responses.
I am actually more interested in specific laser scanner models that fit that purpose ( hot lining scanning ) rather than in the cooling of these lasers.
I read the description of FARO lasers (specifically S70 and S150 models) , it is somehow implicitly stated that these lasers can be used to scan the refractory lining but i have some doubts.
What Riegl models would you suggest?
Also waiting forward for the response of the former employee of the company.
Thanks!

Re: Scanning of very hot surfaces. Advice needed.
Hi all,
a few years ago i tested a Focus X330 on hot material.
The part was heated to around 1300°C and we tried to scan every time the part cooled down 50°C.
The first time we got signal back and the data showed the object was between 850°C and 900°C.
So, no job for a Focus!
I would also prefer a long range system which uses a pulsed signal!
Hope this helps!

Dear Sergey,
my colleague replied. What I didn't know: the company still exists.
He will put you in touch with them. Please check your private messages - I've forwarded his email address to you.

Hi
Maybe the LaCam product line meets your requirements: https://www.mineralstech.com/business-s ... cam-family
Here is a video of a torpedo laddle scan: https://youtu.be/Rl0q7vN8cB8
Or steel laddles: https://youtu.be/JEIVjiCafwQ.
I hope this helps,
Christian

Dear Daniel Wujanz, good day and hope you doing well.
Could you please give us some additional advice for such type on scanners for hot surfaces? If it possible, of course, maybe your colleague could help us with such system.
Thank you in advance for your prompt reply
