Furnace slag has the following three types handling ways: high-temperature slag natural cooling to become hard dry residue; water quenching the high temperature liquid slag to become loose water residue; blow scattered high temperature liquid slag with steam or compressed air to become fluffy wool slag.
The raymond mill, high pressure grinding mill, coal grinding mill, powder grinding mill, ring medium, vertical milling machines and other steel mill can process blast furnace slag to the slag powder with appropriate fine degree to meet the production needs of multiple industries. The R & D of furnace slag comprehensive utilization is important to many steel enterprises in China to reasonable use their own resources, balance integrated environmental governance issues, and take the road of sustainable development, at the same time can create enormous social and economic value.
In the beginning of the development of the metallurgical industry, blast furnace slag once dumped and buried as waste affected the ecological environment. In the 1960s, with the development of the stirring concrete industry, blast furnace slag powder is used widely as an independent component of concrete and active admixture, and Europe and the United States also developed a national standard for it. The research and development of micro-technology of blast furnace slag in China started in the 1990s, some large domestic iron and steel enterprises imported water slag vertical mill production line from developed countries one after another to comprehensive use the large number of slag and turn waste into treasure. Currently, the domestic slag powder production has increased year by year and successfully applied to key state projects, such as the Ring Elevated overseas, Lupu Bridge, the maglev train project, as well as exporting to other countries.
