A mathematical model is developed for calculating the height and outline of the working space in a blast furnace from the batch surface to the axis of the air tuyere, on the basis of data regarding the density, acceleration of the batch flux, and pressure difference of the gas. The optimal working height of blast furnaces in smelting titanomagnetite sinter and pellets is 10.1—21.8 m. For larger furnace height, relatively immobile refractory batch is formed in the bosh and periodically slips to the hearth, with impairment of the furnace's thermal state. The calculated values obtained provide guidelines in the design and reconstruction of shaft furnaces.

  • 这个专业虽然排明很好,但考冶金的人比较少,每年基本上都招不满,也就是说只要能上东大工科线的基本都能上的,不用担心复试被刷!!
