Chapter 2Implementation of New Technology

Toulouevski, Yuri N.; Zinurov, Ilyaz Y.

Pages: 25 –43

[Advantages and disadvantages of conveyor and shaft furnaces using the new technology and operating with flat bath are examined. Basic performances of these furnaces are compared with those of modern EAFs. Furnaces with flat bath having a number of important advantages, however, lag behind modern...
