Description

Swirling tuyeres of pure plate are produced, using pure cooper plate with high thermal conductivity as raw material, and then they shall become finished products by being shaped specially and welded. This product has sound water channels structure. Its ues-life is greatly lengthened with assured velocity of the water, which makes stable and high-yield blast furnace possible.

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 98136°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°C300°C, half lower than casted intermediate cooler.

b)    The realiable technical solution can prevent deformation.

 

2.    Under normal condition, working life of monkey300days, intermediate cooler1000days.

Company Profile

Liaoning Xi Gang Metallurgical Equipment Co. LTD. is a specialized company which possesses more than twenty years’ experiences in manufacturing blast furnace spare parts. The patent products, i.e. copper plate welded cross-flow long life tuyere (patent No.:ZL200520091270.4) manufactured by my company have been used in different volumes of blast furnaces of 450m3   960m3   1070m3   2600m3  2850m3   3200m3   4747m3  5800 m3  in Chinese iron making enterprises and have gained excellent results. My company is willing to establish cooperation with iron and steel enterprises all over the world with fine-quality products and considerate service.

Major technology characteristics of copper plate welded cross-flow long life tuyere

Adopting the design of letting water flow directly into the internal layers of the front part, after rotating into external layer water passages, then, being excluded via rotation, effectively avoiding cooling dead corner and scale deposit, smoothly conducting heat so as to increase tuyere service life.

Adopting split welding technology for manufacturing, all the raw materials are pure copper plate or pure copper forging parts, via rolling and squeezing technology processing for welding forming, as a result, it ensures the quality, prolongs the service life, reduces the tuyere self-weight and being convenient for operation in front of blast furnace. 

Adopting the technology of hard surface high temperature wear resisting on easy-to-wear parts so as to greatly increase tuyere service life.
