Blast Furnace Technology

http://en.wikipedia.org/wiki/Blast_furnace

Dear PWSlack

Thanks for your reply to my request, by the way I already access en.wikpedia.org and I get basic information from this website.

Do you have any kind of information releted to the design of the blast furnace and hotblast stove and what kind the best selected energy that can we use to produce pig iron?

Once again thank you very much my gurus

Best regards

The "Hismelt process" is the latest I could find....

"The Hismelt process turns iron ore into pig iron, the mix of 96% iron and 4% carbon that is the raw ingredient in steelmaking. For a century following a clever 1856 invention by Henry Bessemer, pig iron came out of blast furnaces that smelted the ore with a mix of coke (charcoal made from coal), hot air and additives like limestone that absorb impurities. Then Bessemer furnaces went out of fashion and were replaced by basic oxygen furnaces, which use oxygen in place of the air and thereby accelerate the steelmaking process because oxygen burns more efficiently than air, which is only 21% oxygen.

Now, at least for certain grades of iron ore, Hismelt may make blast furnaces obsolete. It cuts costs by accepting cheaper ingredients. In lieu of coke, it uses coal, even cheap high-sulfur coal. And it can accept low-grade iron ores contaminated by phosphorus. The Hismelt process cuts down on the emissions coming out of the smokestack. It is more energy-efficient, too, consuming less coal per ton of pig iron than a modern basic oxygen furnace."

Get a hold of a copy of the making, shaping, and treating of steel. It used to be published by USSteel. You should be able to buy a used copy someplace online. Now the iron and steel society put it out.

It is the absolute best reference for your query.

Everyone is so tuned in to online sources that they forget about books.

I can think of no way to better absolutely destroy one's local environment than to try to make steel on a small non-modern non-engineering basis.

I have worked in a coke making, Blast furnace, continuous casting, bar rolling, and cold finishing mills. Slag crushers, iron ore boats, and sintering plants.

The impact of a blast furnace and needed ore, limestone and coke making facilities takes an incredible environmental toll. You will be trading your quality of life for a very low price.

Where I live used to have blast furnaces in the 1800's. Local mines for coal etc.

The mines continue to cave in (subsidence) and when ever someone starts new construction they often find old slag pockets leaching all kinds of sulfurous contaminants.

This will not be a easy or minor scale project. And you will have only iron, not steel to show for your efforts. steel making is yet another step.

Buy steel. from companies with responsible environmental controls and energy efficient processes. You will create merely localised environmental stress trying to do it on a Do it yourself basis..

Even the chinese gov't is trying to close small beehive cokeries and local steel works. They aren't really free market, but they see the waste of resources and environmental destruction that result.

Steelmaking is not a cottage industry in today's world.

As an alumni of the steel industry after 30+ years, I second everything you have offered to the subject.

The Making, Shaping and Treating of Steel is the Bible of the Industry; however, I am unsure of whether it is now out of date from the standpoint of newer technologies.

Dear Who is person reply with aqua doc

I will try to contact to get information from Making, Shapping and Treating as bible of industry

Dear

Go to steel companies websites or association related to steel .

You will get latest & updated news related to blast furnace technologies.....

Bcoz its my experience

Hello Blastfurnace is a specially shapped steel vessel inside vessel lined with refractery.This vessel is called counter current reacter because Solid and gas moves opposite directions coninuously.Temperature is maintainted at 2200 degree centigrade. It helps to produce Iron knows as hot metal. Thermodynamically furnace closed system.

Input material :Iron ore,Coke,Limestone,Oxygen

Out put: iron metal liquid,Co Gas
