    • The present invention relates to a method of manufacturing a stem of a slag dart used to separate molten metal from a slag in a converter to improve productivity, and to save labor force as well as minimize defect rates of the stem by simplifying a manufacturing process of the stem. That is, the present invention relates to method of manufacturing a stem, and the method includes: preparing a molding device having a mold vertically provided on an upper surface of a frame to which a vibrator is attached; a conduit, a refractory, and a core member having a washer which has an outer diameter identical to an inner diameter of the conduit fixated to a border between a screw rod formed on a front end of the core and a core rod formed at a rear end of the core; inserting the conduit inside the mold to adhere an outer surface of the conduit to an inner surface of the mold; inserting a steel core member on a center of the conduit in the mold in a manner such that the screw rod formed on the front end of the steel core is primarily introduced while allowing the screw rod of the core to pass through a through hole formed in a frame of the mold, and a washer formed on an end of the screw rod mounted on the frame; coupling a nut to the screw rod of the core passing through the through hole of the frame to fixate the core to the center of the conduit; applying vibration to the mold while filling the refractory inside the conduit; curing the refractory in the mold when the refractory has been filled; releasing the conduit from the mold when the curing of the refractory is completed; and inserting the conduit into a high temperature drying furnace to burn the conduit while drying the conduit such that a stem having a refractory sleeve remains.
    • 本发明涉及一种制造用于将熔融金属从转炉中的炉渣中分离出来以提高生产率的渣渣棒的方法,并且通过简化制造过程的简化制造过程来节省劳动力以及最小化茎的缺陷率 茎。 也就是说,本发明涉及制造杆的方法,该方法包括:制备模制装置,其具有垂直设置在其上安装有振动器的框架的上表面上的模具; 导管,耐火材料和芯部件,其具有垫圈,该垫圈具有与形成在芯的前端上的螺杆之间的边界上固定的导管的内径相同的外径,以及形成在后部的芯棒 核心结束; 将导管插入模具内以将导管的外表面粘附到模具的内表面; 将钢芯构件以模具中的导管的中心插入,使得形成在钢芯的前端上的螺杆主要被引入,同时允许芯的螺杆穿过形成在通孔中的通孔 模具的框架和形成在安装在框架上的螺杆的端部上的垫圈; 将螺母连接到穿过框架的通孔的芯的螺杆上,以将芯固定到导管的中心; 在将导管内的耐火材料填充的同时向模具施加振动; 当耐火材料填充时,固化模具中的耐火材料; 当耐火材料的固化完成时,从模具中释放导管; 并且将导管插入高温干燥炉中以在干燥导管时燃烧导管,使得具有耐火套筒的杆保持不动。

    • Introduced are a block using ferronickel slag, a method for producing the same, and a device for producing the same. Energy efficiency is improved, and environment contamination can be prevented. Also, a brick having an ensured level of strength which is the same as or higher than a standard value can be produced. The method of the present invention comprises the steps of: preparing high temperature ferronickel slag having a particle size of 0.6-12 mm and produced in an electric furnace steelmaking process; pulverizing the ferronickel slag to have a size of 5 mm or less; sorting the ferronickel slag by particle size; absorbing heat radiated from the ferronickel slag using a fluid; sorting the pulverized ferronickel slag through magnetism in order to be classified into magnetically attachable powder and magnetically non-attachable powder; drying the ferronickel slag; mixing the pulverized slag and a new aggregate by heating the same using the heat absorbed from the ferronickel slag; and molding the same.
