Embodiment 1
[0012] Example 1: A method for reducing smoke on the material surface by spraying on the blast furnace lowering line. The method includes the following steps: 1) The principle of scientifically preparing the wind-off material. After the blast furnace lowering line, spraying and repairing the lining of the furnace body must be scientific. The off-air material is carefully prepared and loaded into the blast furnace in strict accordance with the off-air material plan, which is not only conducive to construction, but also conducive to the resumption of production of the blast furnace. Dolomite is a compound salt of calcium carbonate and magnesium carbonate with the molecular formula CaMg(CO 3 ) 2 , the decomposition equations of pure calcium carbonate and magnesium carbonate are:
[0013] CaCO 3 = CaO + CO 2
[0014] MgCO 3 =MgO+ CO 2
[0015] The decomposition boiling temperature of pure calcium carbonate is 910°C, and the decomposition boiling temperature of pure magnesi...
