Abstract

Çelik ürünlerinin yeniden ısıtılması için fırın olup, yanal brülörler ile donatılmış boylamasına cidarları ve ürünler için bir giriş ve bir çıkış ile donatılmış uç enlemesine cidarları içerir; fırın, girişte bir geri kazanma bölgesini (R), bunun hemen ardından, ürünlerin ilerleme yönünde bir ön ısıtma bölgesini, ardından ardışık ısıtma bölgelerini içerir; fırının hemen girişinde bir duman boşaltma kanalı (5) sağlanmıştır ve bu şekilde ters yönde sirküle ederek boşalan dumanlar, geri kazanma bölgesini kat eder; fırın, ön ısıtma bölgesinde alev modülasyonlu yanal brülörler ile donatılmıştır böylece üründe istenen özellikle eğimli herhangi bir sıcaklık profilini geri kazanma bölgesinden (R) itibaren oluşturmak amacıyla geri kazanma bölgesinde tercih edilen bir duman akışı (4) üretilir.Furnace for reheating steel products, comprising longitudinal walls equipped with lateral burners and end transverse walls equipped with an inlet and an outlet for the products; the furnace comprises a recovery zone (R) at the inlet followed by a preheating zone in the direction of the products advance, followed by successive heating zones; A smoke discharge duct (5) is provided immediately at the entrance of the furnace so that the fumes discharged by circulating in the opposite direction traverse the recovery zone; The furnace is equipped with flame-modulated lateral burners in the preheating zone so that a preferred smoke stream (4) is produced in the recovery zone in order to create any particularly inclined temperature profile desired in the product from the recovery zone (R).
