1. Compared with plastic cups, ceramic cups have less harmful gases and substances brought by plastic cups. According to experts, long-term use of plastic cups may cause cancer.
2. The ceramic cup is completely harmless, it will not be like the metal cup, and there is the possibility of ingesting harmful metals in long-term use.
3. Due to the existence of the ceramic cup, the molten iron is not in direct contact with the carbon bricks, which relieves the infiltration, erosion, erosion and other damages of the molten iron and alkaline substances to the carbon bricks from the structural design, and mullite, brown corundum, etc. All are high-grade ceramic materials with low thermal conductivity, with high resistance to erosion and erosion. Eliminate the embrittlement layer of large carbon bricks.
4. Increase the temperature of molten iron and reduce heat loss: The ceramic cup is made of a material with lower thermal conductivity than carbon bricks, which acts as an interlayer, thereby reducing heat loss through the furnace bottom and hearth. Correspondingly, the molten iron can be maintained at a relatively high temperature, creating good energy-saving conditions for the next step converter production.
5. Easy to rewind operation: Due to the thermal insulation effect of the ceramic cup, the heat loss is reduced during the blast furnace shutdown period, which is conducive to restoring normal operation during rewinding.
6. Prevent molten iron leakage: because the ℃ isotherm, that is, the solidification line of molten iron, is close to the inner surface of the furnace lining, and is moved close to the inner surface of the furnace. Moreover, due to the slightly positive residual expansion of the refractory material, the brick joints are narrowed, so the molten iron Penetration is limited so that the risk of hearth burn-through is minimized.
