| Abstract: | The microstructure and the properties of the cementation layer of the converter lance nozzle with multi-element cementation have been studied and examined The capacities of resistance of the compound material made of the cementation layer and copper matrix to the thermal stress, thermal fatigue, thermal shock have been analyszed. And the cementation lance nozzles were used at Angang. The facts show when cementation technological process and the thick of the cementation layer are suitable, the average heat life of the cementation lance nozzles was increased by 22%. |
