从设计高炉出发,基于液泛现象和流态化现象的临界条件确定最大炉腹煤气量,用高炉炉腹煤气量指数验证计算的合理性,而最大炉腹煤气量对应于最大鼓风量。在本设计高炉冶炼条件下,为避免流态化现象和液泛现象的发生,冶炼1t生铁所允许的最大炉腹煤气量为1 444.59m3,最大鼓风量为1 107.64m3。
Based on the design of a blast furnace, the maximum bosh gas volume is calculated according to the critical conditions of flooding and fluidization phenomena,and the rationality of the calculation is checked through the bosh gas index. The maximum bosh gas volume corresponds to the maximum blast volume. Under the given conditions to design the blast furnace, the maximum bosh gas volume and the maxmum blast volume are 1 444.59 m3/t and 1 107.64 m3/t respectively that can avoid the happening of flooding and fluidization.
