Water model experiments were carried out to understand the mixing behavior of reducing agents in molten slag through vortex stirrer, which makes use of a gravitational energy to mix reducing agent in the molten slag without imparting artificial energy. At a water flow rate of 6 L/min vortex was not generated, and a stable vortex was formed when the water flow rate was 7 L/min or higher with the present experimental apparatus. Water level increased linearly with increasing the water flow rate. In the upper vortex region, the vertical and horizontal velocities slightly decreased with increasing the water flow rate, whereas those in the lower vortex region increased remarkably. Accordingly, strong mixing behavior was obtained in the lower vortex region. Owing to the strong centrifugal force, particles move downwards with approaching the funnel wall. When 40 grams of polypropylene particles added to the lower vortex, they were instantaneously mixed well.

Up to date, the life extension of industrial plant structures has been strongly required in the field of iron-manufacturing company, atomic or power generation company and so on. Fault monitoring, maintenance of aging structural components, safety assessment and residual life prediction may be recognized as typical and/or practical methods in terms of life extension methods. Based on the construction of damage scenario, precise analysis method and development of the risk or reliability assessment, a number of studies have been carried out in this viewpoint. In conjunction with the finite element analysis technique, a practical procedure for the safety assessment of iron-manufacturing plant structures was developed in this paper with a particular interest in furnace. By virtue of the detailed finite element analyses for blust furnace under an operational condition, the validity of the proposed procedure for safety assessment was presented.

경기도 안산시 반월공단에 소재한 (주)승진기계는 국내 최초이자 유일의 대형 롤러(Roller)류 전문 제작업체로, 1985년 설립됐다. 이곳은 27년의 역사를 자랑하는 만큼 상당한 생산 및 기술력을 지니고 있다. 프레스용, 사출기용 Tie-bar, 제지용 Calener roll 등 산업현자에서 쓰이는 각종 대형 롤러 대부분을 제작 생산할 수 있는 시스템을 갖추고 있는 것이다. 이런 방대한 능력을 반영하듯 국내 굴지의 기업인 포스코, 현대제철, 두산중공업, 동부제철 등이 이곳과 협력관계를 맺고 있다. 이곳 임직원들은 이같은 우수한 기술력과 생산력의 비결로 '안전을 향한 도전의식'을 꼽는다. 작업현장의 안전이 기술 및 생산력 제고의 원전이라는 신념 아래, 끊임없는 노력을 기울인 결과 지금의 성과를 이룩했다는 것이 그 설명. 안전으로 국내 최고의 대형 롤러 제작업체로 우뚝 서는데 크게 기여한 (주)승진기계의 나란수 공장장을 만나봤다.
