DEMİR-ÇELİK FABRİKALARINDA TRANSFER KAYNAKLI ISI KAYIPLARININ AZALTILMASINA YÖNELİK DMADV METODOLOJİSİ İLE ISI MUHAFAZA SİSTEMİ TASARIMI

Sena Özal1 , Abdulla Sakallı2

Demir-çelik endüstrisinde sıcak haddeleme sırasında slabların tav fırınından haddeleme ünitesine transferi, önemli ısı kayıplarına ve enerji tüketimine neden olmaktadır. Bu çalışmada, transfer bölgesindeki radyasyon ve konveksiyon kaynaklı kayıpları azaltmak amacıyla hidrolik kontrollü, açılır-kapanır pasif bir Isı Muhafaza Kalkanı Sistemi tasarlanmıştır. Çalışma, DMADV metodolojisi kapsamında saha verileri, mühendislik hesaplamaları ve literatür bulguları kullanılarak yürütülmüştür. Önerilen sistem; modüler hareketli kalkan, yüksek sıcaklığa dayanıklı izolasyon, düşük emisyonlu iç yüzey, hidrolik mekanizma ve PLC tabanlı kontrol biriminden oluşmaktadır. Analitik hesaplamalarda, 15 tonluk bir slabda 10°C sıcaklık kaybının yaklaşık 90.000 kJ enerjiye ve 0,28 Nm³/ton doğalgaz tüketimine karşılık geldiği hesaplanmıştır. Sistem, sıcaklık homojenliğini iyileştirme, enerji tüketimini ve karbon emisyonlarını azaltma potansiyeline sahiptir. Bulguların CFD analizleri ve saha testleriyle doğrulanması gerekmektedir

DMADV-BASED DESIGN OF A HEAT RETENTION SHIELD SYSTEM FOR REDUCING SLAB TRANSFER HEAT LOSSES IN HOT ROLLING PROCESSES

Sena Özal1 , Abdulla Sakallı2

During hot rolling in the iron and steel industry, the transfer of slabs from the reheating furnace to the rolling unit causes significant heat losses and increased energy consumption. In this study, a hydraulically controlled, movable passive Heat Retention Shield System was designed to reduce radiation and convection losses in the transfer section. The study was conducted within the DMADV framework using field data, engineering calculations, and literature findings. The proposed system consists of a modular movable shield, high-temperature-resistant insulation, a low-emissivity inner surface, a hydraulic mechanism, and a PLC-based control unit. Analytical calculations showed that a 10°C temperature decrease in a 15-ton slab corresponds to approximately 90,000 kJ of energy and 0.28 Nm³ of natural gas per ton. The system has the potential to improve temperature uniformity and reduce energy consumption and carbon emissions. Further CFD analyses and field tests are required to validate the findings
