Boiler slag heat-resistant cast iron baffle for steel mills

The chemical composition of ductile iron and its mechanical properties are a general term for alloys composed mainly of iron, carbon, and silicon. In these alloys, the carbon content exceeds the amount that can be retained in the austenite solid solution at eutectic temperature. Cast iron is a general term for alloys mainly composed of iron, carbon, and silicon. In these alloys, the carbon content exceeds the amount that can be retained in the austenite solid solution at eutectic temperature. Iron carbon alloys with a carbon content of over 2%. Industrial cast iron generally has a carbon content of 2% to 4%. Carbon often exists in the form of graphite in cast iron, and sometimes also in the form of cementite. In addition to carbon, cast iron also contains 1% to 3% silicon, as well as elements such as manganese, phosphorus, and sulfur. Alloy cast iron also contains elements such as nickel, chromium, molybdenum, aluminum, copper, boron, etc. Carbon and silicon are the main elements that affect the microstructure and properties of cast iron
