\u00c7elik \u00fcretimi, sanayinin en temel ve \u00f6nemli s\u00fcre\u00e7lerinden biridir. Bu \u00fcretim s\u00fcrecinde metalurjik i\u015flemler b\u00fcy\u00fck bir rol oynar. \u00d6zellikle s\u0131v\u0131 demirin \u00fcretimi ve i\u015flenmesi, \u00e7elik \u00fcretiminin kalitesini ve verimlili\u011fini do\u011frudan etkiler. Bu makalede, s\u0131v\u0131 demir ve \u00e7elik \u00fcretiminde kullan\u0131lan metalurjik s\u00fcre\u00e7ler hakk\u0131nda bilgi verece\u011fiz.<\/p>\n

S\u0131v\u0131 demir, genellikle y\u00fcksek f\u0131r\u0131nlarda \u00fcretilir.
