Sac malzemelerin yüzeyleri, boyanabilme ve şekillendirme açısından belli bir pürüzlülük profiline sahip olmalıdır. Yüzeyin pürüzlülüğünün az olması boya veya kaplamaların yapışmasını azaltabileceği gibi fazla olması boya veya kaplamanın yetersiz olması sonucunda paslanmaya neden olabilecek ayrıca boya veya kaplamanın fazla kullanılmasına sebep olarak maliyetlerin artmasına sebep olacaktır. Bu sebeplerden dolayı, sac malzeme yüzeyinin en uygun seviyede pürüzlülüğe sahip olması istenir. Sac malzemelerin yüzeylerine genellikle temper haddeleme olarak bilinen, özel pürüzlü merdanelerle pürüzlülük profili transfer edilir. Sac malzeme yüzeyine aktarılan pürüzlülük profili, haddeleme parametrelerinden etkilenir. Bu deneysel çalışmada otomotiv endüstrisinde yoğun bir şekilde kullanılan yüksek akma mukavemeti ve uzama kabiliyetine sahip olan AISI 304 paslanmaz çelik sac malzemelere temper haddeleme ile pürüzlülük transferine ezme miktarı, haddeleme hızı, merdane pürüzlülüğü, yağlama koşulları ve malzeme kalınlığının etkisi araştırılmış ve pürüzlülük dağılımı malzeme oranı eğrileri yardımıyla değerlendirilmiştir. Ezme miktarı arttıkça pürüzlülük transfer oranı arttı. Yağlayıcı kullanılan koşullar altında, merdane pürüzlülüğü, malzeme kalınlığı artışıyla birlikte pürüzlülük transfer oranı azaldı. Haddeleme hızının artışı pürüzlülük transfer oranına etkisi olmadığı sonucuna varıldı. Ayrıca düşük ezme miktarı, düşük haddeleme hızı, düşük pürüzlülüğe sahip merdane, kalın malzeme ve yağlı koşulların tercih edilmesi ile daha homojen bir pürüzlülük dağılımına ulaşılabileceği sonucuna varılmıştır.

Investigation of the Effect of Rolling Parameters in Roughness Transfer by Skin-Pass Rolling to AISI 304 Stainless Steel Sheet Materials

Öz

The surfaces of sheet materials must have a certain roughness profile in terms of paintability and forming. As well as low roughness of the surface may reduce the adhesion of paints/coatings, excess of paint/coating may lead to rusting as a result of insufficient of paint/coating also excessive use of paint/coating will cause increased costs. For these reasons, the surface of sheet material is desired an optimal level of roughness. Roughness profile is transferred to surface of sheet materials by special roughing rollers, commonly known as skin-pass rolling. Roughness profile transferred to the sheet material surface is influenced by the rolling parameters. In this experimental study, it was investigated effect of the reduction ratio, rolling speed, roll roughness, lubrication conditions and material thickness on the roughness transfer by skin-pass rolling to AISI 304 stainless steel sheet materials with high yield strength and elongation ability, which are used extensively in the automotive industry and the roughness distribution was evaluated with the help of material ratio curves. Roughness transfer ratio increased as the reduction ratio increased. Roughness transfer ratio decreased with increasing material thickness, roll roughness, under the conditions of using lubricant. It was concluded that the increase in rolling speed had no effect on the roughness transfer ratio. Also, it was concluded that a more homogeneous roughness distribution can be achieved by choosing low reduction ratio, low rolling speed, low roughness roll, thick material and lubrication conditions.
