The method you need to employ isn't a matter of getting the furnace hot enough at all. Take a minute and absorb that basic fact, for steel melts between twenty-six and twenty-eight hundred degrees. Now consider the fact that the even higher furnace temperatures needed to bring a charge up to that range will destroy all but the most expensive furnace refractories, while weakening crucibles to the point where they become rubbery..Iron, on the other hand, melts nicely between nineteen-fifty and twenty-two hundred degrees; a much more comfortable heat range for your equipment.

So, how did industry turn iron into steel about a hundred years back? An oxygen lance was used to burn out excess carbon while simultaneously raising the molten iron to steel liquefying temperatures from the center of the charge, instead of trying to transfer overwhelming temperatures through crucible walls.

Most steel making still uses one form or another of heating steel charges from the center out.

I believe oxygen lances are still the best method for home hobbyists today.

As to Babington burners; I mostly dislike commenting on the competition.

Hi, Marcin, it is very difficult to melt steel ic oil :gas fired furnace because its melting temp is high as 1500 DEG CENTIGRADE, so pl try with induction of arc furnace only , steel needs some alloying elements like carbon , silicon, etc depending on its usage , you can try to build home made inaction melter, as some ref may be available in intranet, that is the way as for i concerned, Best regards, V;Ganesan;
