Steelmaking: Rolling

[@vector8310]

videos like these really make KZbin a valuable resource

[@masonkraft216]

Before being rolled here, the steel has been annealed to very higher temperatures. This makes it much easier to be compressed and molded by the massive machines. It is above its recrystallization temperature so it is much more malleable and the micro-structure of the steel is not affected by the process as much. During cold working, the the steel would be rolled at room temperature, and would require even more pressure and even larger machines for steel of the same size. However, the resulting steel parts would be stronger and have a better surface finish only at the expense of being less ductile.

[@agentorange153]

But it still causes the grains to get smaller, right?

[@keliu882]

A very nice video to understand steel rolling, thanks!

[@Annaynay]

Brilliant. This has helped loads with my Physics Coursework.

[@StuartZiane]

I used to work for a company that manufactured equipment for the TBM at Lackenby. Interesting place to visit.

[@M_ur_tz]

It is a wonderful video. This helped me a lot to understand the process.

[@maciekagh]

Greetings from a student of University of Science and Technology. Good job.

[@spliffy666]

@CorusBCSATraining Trust me, I work in a rolling mill as a maintenance engineer. After a while the heat and noise gets to you. It's still pretty cool :)

[@brogaguy]

you're right. the steel would be brittle through rapid cooling. but they're hard

[@justforever96]

Amazing. Now think of what it was like back in the day, when they still did half this stuff manually. I remember reading a book once describing piece by piece how a steam locomotive was made, and a lot of it was pretty hands on. And this was talking about the 1920's, when things had already advanced a lot.

[@musafawundu6718]

Can you remember the name of that book?

[@bubushhh]

@@musafawundu6718 yh, its called: ligma

[@Lukeriddoch]

loving the universal beams and columns :P

[@2jzgtejza80]

@Calabrez In this process, yes, but there's many other process where you need cool down very fast to get very hard and strong surface (carbides)

[@tr1ckky7181]

you need to get a video of the coil box in action in strip products....

[@Calabrez]

I guess the cooling process must go on slowly, otherwhise you might damage the steel with tiny cracks that later can lead to a building crashing or something similar. Just like it happens when you have, at home, a hot glass pan: if you submerge it, it might crack all the grass.

[@MrChefMedz]

Very Interesting, Thank you for the information.

[@Hub3rtCumb3rdal3]

lol I have no idea what I'm watching but what ever this is it's awesome.

[@dnicholsoncole]

We hope to be adding more to this area soon. I am expecting some more videos, or updates of the existing.

[@chrishelenrose]

good vid, i had lots of years in a rod mill, ended as a rollerman.

[@maciekagh]

All of your videos are very helpful. Thanks (I know all of these processes cause I`m a student of metallurgy science - metal forming exactly :) )

[@davemwangi05]

i love mild steal. theese is really owsum

[@dnicholsoncole]

thanks! hope its educational. however, i am having great difficulty getting more videos to extend the site.

[@Governmentwallah]

Very nice animation

[@RODALCO2007]

Good educational video, thanks for shareing.

[@SamFBM]

always thought they were 3 pieces of flat bar welded together lol

[@robertgreen6027]

So tank armour was made this way in ww2? Or was it different?

[@bhanotboyz]

quite high level of accuracy

[@VinnyMartello]

Very informative!!!

[@maryambagheri3449]

Hi, I am looking for a hot rolling calibration design software. Can you guide me?

[@alvinstephens3557]

Are they still going

[@EngineerPEretired]

Can I please use some of your content for educational use? I will tell people you are my source... i want to show people that not all steel is welded ...

[@chrishelenrose]

@anujjsolanki sure what would you like to know?

[@alexandrpylyushenko7116]

Nice video!

[@bestamerica]

' is this company steelmaking can make any arms weapons, big guns, tanks, warships, builds, spacecrafts

[@Beefmouth]

Good video!! I work in a Slabcaster in the slabyard, we make steel slabs and the best armor plate around!! heh

[@VinnyMartello]

Slabcaster. That’s a rock band waiting to happen.

[@CanadianPunker62]

@@VinnyMartello Kind of surprised it's not a Sludge metal band already lol

[@ChinesehammersAnYang]

Wow, So nice!

[@mc_brown_bear]

was that Scunthorpe Plate Mill?

[@Retroearthling]

I never wondered how big steel pieces were made until tonight. Amazing. Who thought of this stuff?

[@MrPeerum]

put the video on 1080P full HD.

[@19tebanksy12]

Seeing as this video was clearly made quite a long time ago, it likely predates television even using 720p (standard definition). That means that this was not even filmed in HD, so if the author of this video uploaded it in that resolution it wouldn't look any different.

[@bryawn2428]

why isn't there steam at the end when liquide falls on the red steel ??

[@TheDoof1]

BRYAWN Leidenfrost effect.

[@dec5551]

great video thanks!

[@dnicholsoncole]

@WaterfrontBoss Hi there, this is David NC who maintains this site. I am hoping to get Corus/Tata to send me more videos to put up here in the autumn. If you send me the links to the ones you have made, I can Favourite them on this site and add them to Playlists. Or use Sendspace or a similar method to send the actual movie for me to upload. (PS, I am not paid to maintain this site, it is funded by users clicking on adverts, so please click as much as you like).

[@Sanjay2177]

Its a good technic

[@dnicholsoncole]

@Nopartyforme82 They would not be a person for very long after trying that!

[@Iceis_Phoenix]

Satisfying

souldn,t take long.

Where's Carl Segan so he can say "Billions and Billions"?

[@erdeinorbert]

They see me rollin.. they hatin

[@PigsCanFly99]

tricky business .. if mill stops .. hot steel will damage rolls ... the show must go on. Also notice complicated looking cooling stage .. why not just submerge cool? Tricky business.
