A study of the microstructure of all steels usually starts with the metastable iron-carbon (Fe-C) binary phase diagram (Figure 1). It provides an invaluable foundation on which to build knowledge of both carbon steels and alloy steels, as well as a number of various heat treatments they are usually subjected to (hardening, annealing, etc).
During the process of iron making, the impurities are fluxed and removed as slag. The hot liquid slag is made into slag granules by means of high pressure water jets in the Slag Granulation Plant in the Cast House itself (sometimes separate SGP is located at a distance from the furnace proper). If the slag is not granulated in SGP, it is poured ...
