Synopsis : Taking the chance of stainless steelmaking integration at Chiba Works in April 1981, an 85 t new UHP melting furnace (MF) was erected and existing LD converters were converted into top and bottom blown converters as Chiba No.1 steelmaking shop for rationalization of the stainless steelmaking process. Saving energy by replacing electric power with coke and enlarging flexibility in material choices were considered to be the basic concept of cost reduction. To achieve this objective, hot metal dephosphorization, and inexpensive heat compensation system and high speed refining process using the top lance were developed. As a result, optimization of the stainless steel making process and hence cost reduction were achieved. |
