Well, let me tell you, I heard a thing or two about them structural steel beams. They say those things are rolled when they’re hot, hotter than a furnace in July! You see, they gotta be hot, real hot, to get all bendy and shaped up right.
Now, why would they go and heat up steel like that? Well, that’s ’cause hot steel, it’s like butter, kinda. It gets all soft and easy to move around. That’s how they make them beams, I reckon. They heat ’em up and roll ’em out. They call it hot rolling, I heard.
They say it makes the steel strong, stronger than an ox! When that metal is all warmed up, it just does something, I don’t know what, but it makes it tough. It’s like baking a pie. You gotta heat it up just right to make it good and sturdy.
This hot rolled steel, they use it for big things, you know? Like them I-beams, and them columns, the things that hold up buildings and such. They don’t need to be perfect, just strong. And it’s cheap, too! Cheaper than cold, I suppose.
- Hot steel is easier to shape.
- Hot rolling makes steel strong.
- Structural steel beams are made with hot rolled steel.
I heard they paint them beams red, a special kind of red. It’s called Red Oxide, like the color of rust, but it ain’t rust. No sir! It’s to keep the rust away, keep them beams strong for a long, long time. Smart, ain’t it?
So, this hot rolling, it’s like this. They heat up the steel, way over 1,700 degrees! That’s hotter than a firecracker on the Fourth of July! And that’s hotter than the temperature steel can change its form. Makes it easy to squish and shape, you see.
They got these big rollers, I imagine, and they just roll that hot steel out like dough. They keep rolling and rolling until it’s the shape they want, an I-beam, or whatever they need. I reckon, they make different beams for different buildings.
I heard them say that this hot rolled steel has a good grain structure. It sounds important. I guess it means it is all packed in tight, making it strong. They are known for structural integrity. That means they are strong enough to hold things up.
They say the steel comes from a mill, all hot and ready to be rolled. Then, they heat it up again, make it even hotter, and run it through them rollers. That’s how they make girders, and beams, and all sorts of things. Big, thick things, mostly.
They use automated machine to roll it. Must be noisy! That’s what I guess. They heat it up until it is like hot dough, then push it through those automatic rolls. After that, they got a basic beam shape.
Now, cold rolled steel, that’s a whole other thing. That’s for when you need things to be just so, I guess. They take that hot rolled steel, and they cool it down. Then they do something else to it, anneal it, or temper it, or something. I don’t rightly know what that means, but it sounds fancy.
But for them big beams, hot rolled steel is the way to go. It’s strong, it’s cheap, and it gets the job done. Just like a good mule, it’s reliable and doesn’t need to be pretty. It just needs to be strong.
So, there you have it. That’s what I know about them structural steel beams. They’re rolled while they’re hot, and that’s what makes ’em so strong. It is a good way to make those steel beams.
- Hot rolled steel is used for I-beams and columns.
- Red Oxide paint protects the steel from rust.
- Hot rolling makes steel strong and affordable.
Hope that clears things up for you. It ain’t rocket science, just good old-fashioned steel making. It is like baking a cake. You need heat. That’s how they make strong beams for building.
