Construction method of blast furnace hearth carbon ramming material
The invention discloses a construction method of a blast furnace hearth carbon ramming mass, which is characterized in that a gap area of a blast furnace is heated, so that the temperature of the gap area, needing to be filled with the ramming mass, of the blast furnace can be close to a temperature range, namely a working temperature range, corresponding to the gap area when the blast furnace works. Under the condition of the working temperature range, in the filling and ramming process of the ramming material, the temperature condition is almost the normal working temperature condition of the blast furnace. The working temperature range is wide, and the plastic condition of the carbon ramming material is improved. During ramming, the ramming material is partially volatilized, shrunk in volume and plastically deformed at a relatively high temperature, so that the ramming material is more compact and uniform. And air gaps and cavities of the ramming material in the working production process of the blast furnace in the later period are reduced, so that the obtained ramming material is filled more tightly and compactly. The problem that when a blast furnace is used, ramming mass in the blast furnace volatilizes or shrinks to generate air holes, and the heat conductivity of the blast furnace is affected is solved to a certain extent.
本申请公开了一种高炉炉缸碳素捣打料的施工方法，对高炉的缝隙区域进行加热，以使高炉需要捣打料填充的缝隙区域的温度，可以接近高炉工作时缝隙区域所对应的温度范围，即工作温度范围。在工作温度范围的条件下，捣打料在填充捣打的过程中，所处的温度条件几乎就是高炉正常工作的温度条件。工作温度范围较高，改善碳素捣打料的塑性条件。捣打料捣打时在较高温度下的部分挥发、体积收缩以及塑性变形，更加利于捣打料的密实和均匀。减少后期捣打料在高炉工作生产过程中出现气隙和空腔，使得到的捣打料的填充更为紧密与密实。一定程度上解决高炉在使用时，高炉内的捣打料挥发或缩小出现气洞，影响高炉导热性的问题。
