The decrease of steel level will also cause slag inclusion. If there is sufficient time for the plug bar to close the immersion nozzle, the steel level can be reduced to below the allowable limit. If the pouring starts again, the molten steel will inhibit the mold protection slag, resulting in slag inclusion.

Steel is primarily produced using one of two methods: Blast Furnace or Electric Arc Furnace. The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved, the processes ...

To evaluate the energy potential of steel mill slag, the volume of BF iron and steel production has been examined. Figure 2 (elaborated with data from IISI 2009; WSA 2011) shows the evolution of worldwide production of BF primary iron and can be seen that there is an increasing tendency for both products during the last 10 years.

Carbon capture and storage (CCS) technology can reduce CO2 emissions by 85 to 95% for power plants and kilns with high CO2 emissions. Among CCS technologies, carbon dioxide capture using steel slag is a method of carbonating minerals by combining oxidized metals in the slag, such as CaO, MgO, and SiO2, with CO2. This study assessed the amount of CO2 captured and the sequestration efficiency in ...

Steel slag's usage is related to its physicochemical characteristics. The density of steel slag is g/cm 3. Steel slag is hard because of its high Fe amount and is highly resistant to corrosion. The grindability index of steel slag is [38]. Steel slag primarily consists of SiO 2, CaO, Fe 2 O 3, FeO, Al 2 O 3, MgO, MnO, and P 2 O 5 ...

The rolling process begins by continuous casting 7, or if an older, not modernized steel plant is considered, by ingot the most modern mills continuous casting is followed directly by hot rolling. In all of these cases the prerolling structure consists of dendrites which are subsequently removed in the reheat furnaces in which most of the alloying elements enter into solid solution.
