7TH EUROPEAN COKE AND IRONMAKING CONGRESS - ECIC 2016

The requirements concerning the coke quality for the blast furnaces of voestalpine increased steadily in the past few years. To achieve this improved coke quality, on the one hand side the raw material base had to be changed and on the other hand side the coal pre-treatment and the blend preparation had to be enhanced. Originally the coal preparation plant at the coke oven plant voestalpine was designed in 1940. Although during the years a modern hammer crusher and a separation unit for impurities had been installed, the coal preparation plant was not state of the art anymore. In the course of this project the coal preparation plant was improved to ensure a constant blend quality and thus meet the requirements concerning coke quality of the blast furnace.
