In this paper, the representative process combined-blowing oxygen converter process with a scale of 3.7×106 continuous casting billet annual is designed.. In the workshop, main equipments including 2×150t converters and its auxiliary equipments with 2 LF refining furnaces, 2 sets of slab continuous casting machines and a set of billet continuous casting machine are designed. The Smelting period is set for 38 minutesin which the actual oxygen blowing time is only 16 minutes. Depending on the development trend of steel-making process and the quality requirement of carbon steel and pressure vessel steel, LF refining is selected to fufill continuous casting. Finally,the following process flow is choosed: Pretreatment→Converter→LF→CC. On the base of the material and heat equilibrim caculation,the size of steel-making plant workshop span and device assign, personnel placement is made .A project instruction is redacted ,funace size graphic, a ground plane and a sectional view of the workshop are also submitted. And finally, the monograph which
