Description
Silicon-zirconium is a powerful deoxidizer, denitrification agent and alloy additive in the steelmaking process. It is used in high-temperature alloy steel, low-alloy high-strength steel, ultra-high-strength steel and cast iron. Zirconium can refine the austenite grains of steel; it can be sulfided to synthesize zirconium sulfide to prevent the hot brittleness of steel; zirconium can also reduce the strain aging phenomenon of steel and improve the low-temperature toughness of steel. The role of zirconium in cast iron is similar to that of titanium. It can form zirconium carbide with the carbon in the molten iron and promote the formation of graphite during cooling. A small amount of zirconium is beneficial to the graphitization of white cast iron, so that the white cast iron is grayed, and the annealing time is shortened in the production of ductile cast iron.
