Abstract

The operating conditions of cast steel staves at Masteel blast furnace have been simulated to generate the temperature distribution under different operating conditions. The influence of the temperature and velocity of cooling water as well as the gas temperature of blast furnace on the temperature distribution of the cast steel stave was obtained. The main cause of stave damage is discussed. The result shows that cast steel staves possess better heat transfer ability and a lower temperature distribution field than nodular cast iron staves, but their performance is much less satisfactory than that of copper staves.
