济钢320t鱼雷罐温降分析及改进保温措施研究

ANALYSIS ON TEMPERATURE DROP- DOWN OF THE 320T TORPEDO TANK AND IMPROVEMENT OF INSULATION MEASURES

针对济钢铁水运输装备320t鱼雷罐从高炉至转炉运输距离长,铁水温降速度快,研究分析了济钢320t鱼雷罐在重罐和空罐时的温降机理及温降原因,从提高鱼雷罐保温效果出发,改进鱼雷罐运行模式及采用高效保温材料以达到大幅度降低铁水过程温降速度,为济钢转炉降低能源消耗提供有效保障。

Aiming at the problem of long distance transportation of Jigang liquid iron equipment of 320 t torpedo from BF to converter and fast temperature drop speed,the paper studied the temperature drop-down mechanism and cause of the 320 t torpedo in both fully- loaded and empty- loaded conditions.From the point of improving torpedo insulation effect,the operation mode is improved and the efficient thermal insulation materials are used to reduce significantly the temperature drop rate. As a result,effective measures are provided to reduce energy consumption in converter.
