How do you melt steel without a blast furnace?

Question

Is there any way to melt steel without the intense heat of a blast furnace?

Answer 1

Steel melts at a relatively low temperature of between less than 1200 and approx. 1600 degrees Celsius. The problem one encounters with steel is that temperature and carbon content are absolutely critical to get what you want rather than to get what you get.

So unless you have a large anount of steel in a large oven and meticulous process control including chemical sampling, your "product" will end up looking like a piece of iron age metal.

But if all you want is to see steel melt, any old blowtorch will do the job. The metal at the end of the process will be useless for pretty much any technical purposes, though.

How To Melt Steel

Answer 4

Iron melts at a very high temperature, so if the goal is to melt it, then there will be a certain amount of "intense heat" of course.

Steel is recycled in a carbon arc furnace. The bottom is lined in graphite. Large graphite rods are lowered into iron scrap and enormous amounts of electricity melt the iron due to the heating of the carbon due to its resistance. The carbon also removes any oxides by forming CO2. Aluminum and lead can also be recycled in this fashion.

Ordinary rust can be turned into liquid iron through the use of the "thermite" reaction. Rust and aluminum power can be ignited with a propane toarch or a magnesium ribbon fuse. The aluminum is oxidized and the rust reduced to molten iron. This reaction is used to spot weld cracks in steel structures, like railroad tracks. It is also a popular arson device used by spies.

Answer 5

I can use an oxygen-acetylene torch to melt steel. It's called welding. I can also use an electric arc welder if I don't have an oxygen/acetylene gas welder.

Both of those methods melt steel quite well in open air.

Answer 6

Well I think You cant melt steel without furnace. But i will give u sme stupid idea Plz if sme thing happen to you dont blame me:)
1. Put the steel in the fire or gas stove it might melt but it will tkae long time.
2. If your asking this a game site called runescape: You can melted with a 1 nature runes and 5 fire runes
3. Try to heated with something hot...
4. I think if u explain the question bit detaily the users might can answer properly

Answer 7

Make a fire pit outside, start a fire, wait for coal to get to an extreme temperature, place metal in intensely heated coal, this will not melt, but will softening the metal enough to flatten, twist, bend, and shape your metal, all you need to shape your metal is an anvil (an iron table will do fine) and a good mini sledge hammer (any hardware store will have the mini sledge) I hope this helps you. 😄😄😄

Answer 8

in adition to blast furnace we have arc furnace and induction furnace.we can inject oxigen to molten cast iron this causes increasing in temperature because of chemical reaction .

Answer 9

There is a technique to melt various metals in a standard microwave oven. Read about it here
