I think you will find that is money UK government will be paying them to STOP making steel and turn over to being re-melting furnaces, only capable of RECYCLING steel.

Steel was always recycled in the blast furnaces along with primary production.

The chemistry of the blast furnace (Reduction) is hot carbon monoxide gains an oxygen atom to become carbon dioxide. It takes that oxygen from ferric oxide (ore)which becomes iron. Although energy is input to bring the blast furnace up to working temperature, this reaction is exothermic, ie generates heat.

The same applies to the conversion of iron into steel.

The scrap added to the furnace is melted for no cost using this exothermic reaction.

Scrap melted in the electric arc furnace will always be more expensive to recycle than that done in the blast furnace.

All we will get is an uncompetitive industry that cannot be sustained. That will not cause concern to the Indian and Chinese, as they will have the markets and try to supply from their other production facilities.
