1.    Technical Characteristics:

a)    Correct structure dimensions; nice thermal property; dimensions of inside cooling water channels strictly controlled within the designing allowed tolerance; accurate and steady water flow parameter; thermal property within the forecasted scope.

b)    With special structure of cooling channels: ≯5mm structure dimension is adopted for spacer in Nose to Intensify the cooling effectiveness of the end and to reduce the contact distance between hot air and low temperature water.

c)    Surface is treated intensively by over laying welding and its wearability is 7 times higher than pure cooper plate.

1.    Double Inlet& Outlet Tuyere with Following Advantages:

a)    Double inlet& outlet tuyeres of pure cooper plate have 6 high velocity water channels, with water velocity as follows 17.3, 12.8, 10.4, 10.7, 9.8, 8.3,7.4M/s. Temperature of the contact surface between tuyere and water is 98～136°C. High value of lacking heat can avoid burning out.

b)    When the first channel burns out and the inlet& outlet pipe closes, the system of high velocity water still works in the area of 360°C around tuyere.

 

1.    Compared with casted intermediate cooler, the intermediate cooler of cooper plate manufactured by adopting cooper plate welding techniques has two advantages:

a)    With reasonable and scientific multi-loop high velocity water channels, the cooling strength is larger than liquid slag heat strength. As a result, the pouring slag can’t be burned out and the temperature of overall surface reaches about 250°C～300°C, half lower than casted intermediate cooler.

b)    The realiable technical solution can prevent deformation.

 

2.    Under normal condition, working life of monkey≥300days, intermediate cooler≥1000days.
