The Krivorozhstal combine developed a technology for using anthracite in the cold charge on two-bath furnaces in order to conserve pig iron. A feature of this technology is the order of the cold-charging of scrap, anthracite, and lime or limestone. The new technology was compared with conventional techniques to determine its efficiency. The saving in pig iron was 10-11 kg/ton steel. This technology was found to be effective for making ordinary-grade steels. Anthracite characteristics and technology parameters are given. |
