induction vs eaf to produce billets for rebars
(OP)
Hi gents
just discoved this excellent forum, I know this " induction vs eaf" subject has been discussed, my concern is that as far as I know the most of billet producers are using EAF.
In our rolling mill we want to set up a small meltshop with a 10 to 12 tonnes furnace and I want to know two things
can we reach teh below apecified quality for billets
C P S N(1) CEV
0.22% 0.050% 0.050% 0.012% 0.50%
(1)The specified content is the content of free Nitrogen. An excess of the specified values is permitted providing that for each increase of 0.001% N, the maximum P is reduced by 0.005%, the N content should not exceed 0.015% on casted billet.
second point where is the best place to buy a good turn-key project
thank you for your appreciated inputs

RE: induction vs eaf to produce billets for rebars
The real problem with using induction melting is that you have limited ability to refine chemistry. You will need to be very careful about the scrap that you charge. Very careful. It might be difficult to get a good enough supply of scrap to assure that you consistently meet chemistry.

Induction furnace are quick to instal,maintain and operator skills are not demanding. In arc furnace,refractory costs,graphite electrode costs and highly skilled operators are necessary.
However,arc furnace can accomadate all kinds of charge for melting as refining reaction is possible. In induction furnace the charge input has to be carefully selected and maintained.
If you could add a refining process along with induction urnace,nitrogen level controls can be maintained.
Hope this helps,if you need any specific input, I am sure there are many other knowledgeable members ,who can do the needful.

I can't speak to a direct comparison between induction and arc furnace but as others have noted you can get away with cheaper raw materials in an arc furnace than induction.

The value addition,in case of casting manufacturers is better compared to rebar billet producers. Hence,the increased manufacturing costs gets justified for the former.
