Black furnace charcoal ramming material is based on high -temperature electrical cricket non -tobacco coal, artificial graphite, and silicon carbide as the main raw material. Phenolic resin, coal pettea, and coal tar are combined. Between the gap between the carbon brick and the cooling wall of the furnace and the cooling wall above the center of water at the bottom of the furnace.
The function of blast furnace charcoal ramming material is:
1. Fill between the carbon brick and the cooling wall. The gap between the carbon brick and the sealing plate of the bottom of the furnace bottom has a certain intensity and density after being pounded. Requirements for iron leakage and gas;
2. Passing furnace charcoal has an important role in transmitting heat energy. The cooling furnace cooling needs to be passed through the blast furnace charcoal. If the heat conduction coefficient of the blast furnace charcoal pounding the feeding coefficient will affect the smooth transmission of heat, cause the carbon brick temperature to increase, and speed up the erosion of carbon bricks;
3. Black furnace charcoal ramming material is the effect of refractory brick lining. The carbon pounding of the blast furnace is the same as the material of the carbon brick. In the late stage of the blast furnace, if the carbon bricks are burned or leaked and the scum is leaked. It plays a role in refractory brick lining;
4. The carbon pounding of the furnace cylinder has the gap between filling carbon bricks and the cooling wall to prevent leakage of iron water, stab and gas, and absorb the expansion effect of carbon bricks and other fire -resistant bricks to prevent the furnace from preventing furnaces from furnace The shell is too large and cracks.
5. The thermal conductivity of the carbon ramming material is basically consistent with the performance of the carbon brick and the cooling wall of the blast furnace heat. It can ensure that the thermal conductivity is common and does not damage the overall construction structure. Life requirements.
Our company undertakes the supply and construction of a blast furnace carbon in a steel plant. The main points of construction are as follows:
1. Before the construction, the base of silicon carbide must be cleaned and keep the base in a dry state, so that the effect of silicon carbide pounding will be better.
2. When the silicon carbide pounds are pounding, the paving must be uniform, and the paving of each layer cannot exceed 100mm. Each layer of paving is uniformly pounded and then paved layer by layer.
3. Before using the thermal trick, the carbon must be broken and heated evenly. The heating temperature should be dependent on the mixed training temperature of the product. The hot hammer should be used when pounding, and the temperature should not be lower than 70 ° C.
4. The flat -looking operation of the carbon ramming material is flattened. First scrape the flat steel around the flat steel, then shovel the height of the height at the height of the flat steel, and find the flat one by one. When the shovel is flattened, the material must be replenished in the event of a local low position. Dig a low part of the low part with a low part before the material, then fill the material, and then find it. When the surface flatness of the entire carbon mounds basically meets the requirements, then use the flat machine to smooth it until it is completely qualified.
