Abstract

Bu buluş, orta kalınlıkta bir levhanın aralıksız dökümü ve haddelenmesi oluyla üretilen, % 0.12-0.18 C, Si ve Mn'den oluşan ultra ince tanecikli bir sacı ve bunun üretim metodunu ifşa etmektedir. Bahsedilen çelik sacın mikro yapısı özellikle ferrit ve perlitten oluşur. Ferritin ortalama tanecik büyüklüğü 3-7 ?m'dir. Çelik sacın kimyasal kompozisyonu aşağıdaki gibidir: Si: % 0.32-0.35, Mn: % 0.87-1.20, P: <= % 0.02, S: <=% 0.015, kalan kısım Fe ve yabancı maddelerden oluşmaktadır ve bu oranlar ağırlığa göre yüzde olarak verilmiştir. Bu buluş aşağıdaki üretim metodundan yararlanır : 800 °C'nin üzerinde olan sıcak yükleme sıcaklığı ile doğrudan sıcak yükleme ve döküm parçalarının için 1100 ila 1280 °C arasında ısıtılması; parçaların kalınlığını 30-60 mm'ye düşürmek için haddelenmesi; 1-10/s olacak şekilde kontrol edilen haddeleme değirmenleri üzerinde çeliğin ortalama redüksiyon hızı ve 750 - 850 °C arasında kontrol edilen son haddeleme sıcaklığı ile birlikte, çok aşamalı gerilme toplanması ve geniş redüksiyon haddeleme uygulanması; 10-45 °C'lik bir soğutma hızıyla katmanlı soğutma; ve 400-620 °C'lik bir kontrollü sıcaklık altında sarma işlemi.
