Energy Input Steel Pipe Production

Does that include

• getting workers to the mines and back again
• mining the ore
• transporting the ore
• mining the limestone
• transporting the limestone
• mining the coal
• transporting the coal
• making coke from the coal
• assembling the furnace
• starting the furnace
• smelting the ore
• casting the melt.....

Do you now see the vagueness of a question with no boundaries?

Thanks for the reply

Ok…I will explain it a little more detailed:

Lets say I produce a (1 ton ) of Steel used for the later production of (1 ton) a Carbon Steel Pipe 12 Inch Schedule 40…

In is in my interest to find out:

- when a steel manufacturing company got the raw materials and start the production for steel as its final product, energy is needed for a lot of processes beginning at the raw material that is crusched, washed…then, 'Iron Making Process', 'Steel making process' (oth processes BOF and EAF are from interest), 'Casting', Rolling, Coating / Painting, Shaping and ending with steel.

- All kinds of energy (electricity, gas, mechanical…) are from interest

- If you can give me detailed info for each process it would be perfect (i.e. heating up, rolling etc..)

The same for the Carbon Steel Pipe manufacturing process: i.e. raw steel is converted into more workable form (Ignot, blooms and slabs, billet (rolling process), stretching, the pipe making process and so on up to the final processing i.e. straightening)

So:

- Divided by process how much energy is needed (GJ/t)

- And if also applicable, how much carbon is fixed into one ton of carbon steel pipe

For my understanding I also will need to know where those data you collected come from. I need kind of scientific / reliable data.

Thanks again

Hi there,

I do not know who you are but I like you and your comment you - Horrible old bat- you are.

Like the way you addressed this guy's question, as it was really vague. Also like your below comment.

Hav a good day!

Many regards,

Stephen.

This is what I hate about talking to an engineer as a non-engineer (Horrible Old Bat). Instead of trying to understand the question of the unindoctrinated we get a rhetorical response that seeks to make us look unintelligent. You're obviously not helping anybody. Maybe you should ask questions that will help you understand where we are coming from? Of course we don't know how to ask a proper question about your field, otherwise we would be in your field. So if you can't help out, go be a horrible old bat somewhere else - some of us are trying to learn something here. So, what I would like to know: What is the energy consumed per month per ton of steel pipe out the door for a plant that makes casing, tubing, and drill pipe for the petroleum industry? By energy, I mean electricity, natural gas, oil, diesel, gasoline, coal, etc. There is plenty of information on energy consumed for: "getting workers to the mines and back again mining the ore transporting the ore mining the limestone transporting the limestone mining the coal transporting the coal making coke from the coal assembling the furnace starting the furnace smelting the ore casting the melt" There isn't much on what a pipe manufacturing plant consumes per ton of steel. It is a question that can be answered as there is plenty of information on the manufacturing energy requirements for all kinds of other products. Is steel pipe really that difficult to nail down? bryan_k_sell@hotmail.com

Magua,

The rule of thumb for the melting of steel scrap is 500 - 600kWh per tonne. But to give you the energy Input to produce steel pipe I will need more inputs from you. Just as a general point, I have no idea what the energy requirements will be to produce the pipe (the supplier of the equipment should be able to tell you that), but can help you with the steelmaking side of it.

Are you looking for all sources of energy or just electrical energy?

So:

What processes will be employed (Electric Arc Furnace melting scrap, casting in ladles, take it through a pipe caster, etc.)?

What is the raw material (clean scrap, ore, etc.)?

Regards,

TC

Sorry -not a level playing field.

Ok--say from Hot Rolled Coil Coming in:

Simplest will be ERW from already Cold-rolled(by others)- will want(depending on size Specs)-- say 500Kw-Hr /Ton.-This is Forming/Welding mainly.

Tough will be to make Seamless Pipes from Billets : - -depending on size/sizing---~~

2000 Kw-Hr/Ton(Heating/Piercing/3 rolling/sizing/finishing)
