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.
