Abstract

يتعلق الاختراع الحالي بطريقة الصب المستمر لشريط فلزي رفيع thin metal strip تتضمن تحريك الشريط الرفيع إلى قسم تبريد cooling section به مجموعة من منافذ تفريغ المادة المبردة coolant discharge ports مصممة لتفريغ تدفق المادة المبردة على طول الشريط الرفيع؛ الاستشعار الابتدائي لدرجة حرارة الشريط الرفيع لتحديد توزيع درجة الحرارة عبر عرض الشريط الرفيع، وإنتاج إشارة مستشعر sensor signal تناظر درجة الحرارة المستشعرة عند كل من المجموعة الأولى من المواقع. تتضمن الطريقة أيضاً التحكم بشكل مستقل في تبريد الشريط الرفيع عبر عرض الشريط الرفيع بواسطة مجموعة من منافذ تفريغ المادة المبردة في كل منطقة من الصف الأول باستخدام توزيع درجة حرارة محدد إلى درجة حرارة ثابتة إلى حد كبير قبل التبريد الإضافي للشريط للوصول إلى أي درجة حرارة تحول طوري مطلوبة لتحقيق بنية دقيقة منتظمة uniform microstructure إلى حد كبير عبر عرض الشريط. شكل1
