temperature range
Liquid steel is not a pure metal, but a multi-element alloy based on Fe that contains a certain amount of C, Si, Mn, and other elements. Therefore, its crystallization process is not carried out at a fixed temperature (melting point), but is completed within a certain temperature range. Under equilibrium crystallization conditions, crystals begin to appear when the temperature of the steel liquid drops to its liquidus temperature (tL), and crystallization ends when the solidus temperature (ts) is reached. The temperature range between this liquidus and solidus, i.e. tL-ts= Δ Tc. It is called the crystallization temperature range of the alloy. The crystallization temperature range of a certain steel grade mainly depends on the properties and content of the elements contained, and can be determined by the binary or ternary phase diagram of iron and corresponding elements. The influence of various elements on the crystallization temperature range can be approximated as additive. The crystallization temperature range of a specific steel grade.
