Still, among them all carbon is king. STEEL MANUFACTURE. Reference to the chart (Fig. n) shows fourgeneral and characteristic methods of makingsteel — Cementation, Bessemer, Open-hearth,and Crucible. In the following descriptionsof the various processes of steel-making, itwill be interesting to observe how thoroughly. FIG. 12, A BESSEMER CONVERTER BLOWING OFF.
