高炉打水空料线法停炉正在得到广泛应用。此法的优点是节省人力、物力、简便易行,且给下一工序创造了良好的工作条件,具有其它法所不可比拟的优越性。打水空料线法降料线,就是在降料线开始时即停止上料,而以专门设置的炉顶喷水管喷出水量的多少来控制炉顶煤气温度,直至料面降到需要高度为止。在降料线过程中,由于高炉上部空间逐渐增大,且煤气中CO、H_2含量高,以及喷水汽化体积膨胀等原因,不安全因素有所增加。近年来,由于 Blast furnace water empty line method to stop the furnace is being widely used. This method has the advantage of saving manpower, material resources, simple and easy, and to the next process to create a good working conditions, with other unparalleled superiority. Filling water empty line method down line, is in the beginning of the down line to stop feeding, and to set the top of the spout to control how much the amount of water to the roof gas temperature until the required level down to Height up. During the down-line, the safety factor is increased due to the gradual increase of the upper part of the blast furnace, the high content of CO and H 2 in the gas, and the volume expansion of water vaporization. In recent years, due
