  • Control of Airtight Circulating Cooling System for Soft Water on 4150 m~3 Blast Furnace of Baotou Steel
    Science and Technology of Baotou Steel, 2020
    Co-Authors: Liu Ya
    Abstract:

    In the paper,the applications of airtight circulating cooling system for soft water on 4 150 m3 blast furnace of Baotou Steel are introduced. The system could make the cooling system of blast furnace realize cooling with soft water. In productions,the furnace practices could be judged through temperature of cooling system,rate of flow of inlet and outlet,differences in water temperature,reasonable control of liquid level for expansion Degassing Tank as well as changes of thermal load for cooling stave,which could meet the requirements of strengthening smelting for blast furnaces so that the service life of blast furnace could be prolonged.

  • numerical simulation of the two phase flow in novel combined top and corner spray Degassing Tank for aluminum melt
    Advanced Materials Research, 2012
    Co-Authors: Zhi Yong Zhou
    Abstract:

    The Eulerian two-fluid model incorporated with the multiple reference frame approach is adopted to predict the gas-liquid two-phase flow in the novel combined top and corner spray Degassing Tank for aluminum melt. The influence of different parameters, such as gas velocity or hole areas at the Tank corners on the gas-liquid flow behavior is also investigated. Results show that little gas emerges near the wall of Tank equipped with traditional rotating spray degasser. Using the combined top and corner spray degasser, the distribution of bubbles in the Tank, especially near the Tank wall, is improved significantly, which advantages the hydrogen removal. With the increasing gas velocity or hole areas at the Tank corners, the width of ring zone with low gas volume fraction decreases, and thus enhances the effect of hydrogen removal.

  • Numerical investigations of rotating spray Degassing processing for aluminum melt
    Materials Science and Technology, 2020
    Co-Authors: Zheng Rui-xiang
    Abstract:

    In order to reveal the distribution characteristic of purged gas in Degassing Tank for molten aluminum cleansing,the Eulerian two-fluid model incorporated with the multiple reference frame method was adopted to predict the gas-liquid flow field that occurs during the rotating spray Degassing of aluminum melt.The influences of different factors,such as spinning rotor clearance from the Tank bottom,bubble diameter and Tank geometry on the flow fields were analyzed.Results show that argon is apt to escape from the central zones of liquid surface.The melt/bubble interfaces in the area near the Tank wall are seriously inadequate,which decreases the efficiency of hydrogen removal from the melt,and worsens in the longitudinal section with 45°phase angle.The smaller spinning rotor clearance from the Tank bottom,the smaller size bubbles and square Degassing Tank can improve the gas distribution,and thus have the advantage the hydrogen removal.

  • vacuum Degassing Tank and method for Degassing using same
    2011
    Co-Authors: 山本 雅章, 宏典 竹内, 多喜 徳雄, 佳洋 田村, 竹内 友英
    Abstract:

    This vacuum Degassing Tank includes a refractory, in which at least the part that comes into contact with molten slag comprises a carbon-containing magnesia refractory. The carbon-containing magnesia refractory contains 7-28 mass%, excluding 28 mass%, graphite and 3.5-14 mass% Al-Mg alloy, with the remainder comprising magnesia and incidental impurities, wherein the mass ratio calculated by dividing the mass of the Al-Mg alloy by the mass of the graphite is 0.5-2.0.
