Fire doesn’t melt steel either.
Fire melted steel on 4/21
That’s right, Rosie said so.
Open hearth furnaces
Blast furnaces
Cupola furnace
Crucible furnace
Basic oxygen converter
Bessemer converter
Electric arc furnace
Induction furnace
All are capable of generating the 2500 or so degrees Fahrenheit needed to melt iron or steel. The first four do it by burning fuel (fire!). The two 'converters' actually convert iron into steel (lower the carbon content) by blowing either air or pure oxygen through molten iron. The air(O2) blast burns the excess carbon in the iron, raising the temperature and produces steel (& CO/CO2). The last two are electric furnaces although you could make a case for the arc furnace as using fire if you ever get the chance to see one in operation.
In a similar manner oxygen lances and oxy/acetylene torches are used to cut steel and other ferrous alloys by burning it away with an oxygen blast. Once the cut is started you can shut off the acetylene and continue cutting with just the O2 as you are actually burning the steel.
Also, steel begins to loose strength long before it actually melts. That's why a blacksmith heats the metal before s/he forges it into shape. Steel becomes plastic at a dull red heat and will flow into complicated shapes with the application of force between hammer and anvil.
In a nut shell, fire melts steel every day. Steel burns under the proper conditions. Steel looses strength long before it melts. These thing are true and that's a good thing because otherwise we'd still be living in the 'stone age'!

PS FTI Hobbyists make iron castings using their backyard crucible furnaces. Some use propane, others crankcase drain oil to fuel their micro furnaces.
“Fire doesn’t melt steel either.”
Then explain:
Oxy-acetylene torch. I own and use one.
Bessemer converters that are heated with LPG.
You don’t know what you’re talking about.
