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.
