Manufacturing Process of Cast Iron Castings

Making Cast Iron The term cast iron is generally used to describe grey cast iron, but it can also describe a whole group of alloys too. The surface color of the cast iron is often used to identify it. Cast iron begins its life as pig iron, which is remelted and often combined with large amounts of scrap iron and sometimes with steel. Contaminants are removed from the melted pig iron, and the ...

The Ironmaking Process | New Zealand Steel

The final product from the melter process is liquid iron, which is tapped every four hours into refractory lined steel containers called ladles and transported to the steel plant where it is converted and refined into liquid steel. The typical hot metal chemistry of the molten pig iron transferred to the steelmaking process is: Iron (Fe) 95.50%: Carbon (C) 03.40%: Vanadium (V) 00.42%: Titanium ...

Step 2 - Steel making The steel making process is shown in Figure 2. Vanadium recovery Before conversion into steel, vanadium is recovered from the molten iron. This is done firstly because of the value of the vanadium rich slag produced (15% vanadium as V2O5) and secondly because a high vanadium content can make the steel too hard. In the vanadium recovery unit a ladle containing 75 .
