Over the long term, high alumina can also cause a build-up of solids that precipitate from gas in the upper cooler zone on the blast furnace walls. It is possible that the build-up of solid matter can grow and eventually drop into the burden mix. This can cause a temporary cooling of the burden, reducing productivity and increasing coke demand to bring it back up to the required temperature.

Variables Affecting Iron Pellet Properties

Viscosities of high alumina blast furnace slags were experimentally determined by the rotating cylinder method using Brookfield digital viscometer model LVDV-II+ pro. Experiments were conducted in the temperature range of 1573- 1873 K. The effects of temperature, basicity, TiO 2, CaF 2 and silica activity of slags on viscosity were studied. Viscosity decreases with basicity for high alumina ...
