Re: Blast Furnaces
Blast furnaces are a major item in the steel manufacture business, in which metal is melted and most impurities removed before being cast into moulds for a myriad of purposes. They are named blast furnaces because of the high pressure air forced into the furnace to increase the temperature to the required melting point.Re: Blast Furnaces
