1. Ferrous metal is an alloy of iron and iron. Such as steel, pig iron, iron alloy, cast iron, etc. Steel and pig iron are alloys based on iron steel and carbon as the main additive element, collectively referred to as iron-carbon alloys. Pig iron is a product made by smelting iron ore in a blast furnace. It is mainly used for steelmaking and steel making castings. Put the cast pig iron in a melting furnace to obtain cast iron (liquid). The liquid cast iron is cast into cast steel. This cast iron is called cast iron. Ferroalloy is an alloy composed of iron and silicon, manganese, chromium, titanium and other elements. Ferroalloy is one of the raw materials for steelmaking. It is used as a deoxidizer and alloying element additive in steelmaking.
2. Put the pig iron for steelmaking into a steelmaking furnace and melt it according to a certain process to obtain steel. Steel products include steel ingots, continuous casting slabs and straight steels cast into various steel castings. Generally speaking, steel generally refers to steel rolled into various steels. Steel Steel belongs to ferrous metal but steel is not exactly equal to ferrous metal.
3. Steel non-ferrous metals, also called non-ferrous metals, refer to metals and alloys other than ferrous metals, such as copper, tin, lead, zinc, aluminum, and brass, bronze, aluminum alloys, and bearing alloys. In addition, chromium, nickel, manganese, molybdenum, cobalt steel, vanadium, tungsten, titanium, etc. are also used in the industry. These metals are mainly used as alloy additives to improve the properties of metals. Among them, tungsten, steel titanium, molybdenum, etc. Carbide for cutting tools. These non-ferrous metals are all called industrial metals, and there are also precious metals such as platinum, gold, silver, and rare metals, including radioactive uranium and radium.
