1， compared to ceramic cup with plastic cups less harmful gases and substances brought plastic cups， according to experts confirmed that long-term use of plastic cups may have caused cancer.2， ceramic cup is completely harmless， it is not as long-term use may have ingested toxic metals like metal cup.3， due to the presence of a ceramic mug of hot metal leaving no direct contact with carbon bricks， easing the hot metal and alkaline material penetration of carbon brick， corrosion， erosion and other damage from the structural design， and the use of mullite， corundum， etc. low thermal conductivity are advanced ceramic materials with high corrosion resistance and erosion resistance. Eliminate embrittlement layer chunk charcoal brick.4， to improve the hot metal temperature， reducing heat loss: ceramic cup is made of low thermal conductivity than carbon brick material， the role played compartment， thus reducing the exclusion of loss through heat hearth and hearth. Accordingly， the molten iron can maintain a high temperature kiln production process to the next step to create a good energy condition.5， easy re-wind operation: Because heat insulation ceramic cup during the wind blast off， heat loss is reduced， for the resumption of normal operations resume when the wind.6， to prevent leakage of hot metal: Due �� isotherm line that is close to the solidification of molten iron lining the inner surface of the migrated close protection within Further expansion due refractory slightly positive residual swelling is reduced so that the bricks， so hot metal penetration is limited so make hearth minimize the risk of burn-through.
