Abstract

Eksenleri yatay olan iki sogutulan silindir arasinda sivi metalden dogrudan 10 mm'den daha düsük ya da esit bir kalinliga sahip olan ferritik paslanmaz çelik seridin sürekli dökülmesi için bir yönteme iliskindir, bu yöntemin özelligi olarak: sivi metal agirlik yüzdesi ile asagidaki bilesime sahiptir: %C + %N=<0.12, %Mn=<1, %P=<0.04, %Si=<1, %Mo=<2.5, %Cr 11 ve 19 arasinda, Al=<%1 ve %Ti + %Nb + %Zr=<1, bakiye kisim demir ve ergitmeden sonuçlanan yabanci maddelerdir; sivi metalin gama p indisi %35-60 arasindadir, gama p asagidaki formül ile tanimlanmaktadir: yp=420 %C + 470 %N + 23 %Ni + 9 %Cu + 7 %Mn - 11.5 %Cr - 11.5 %Si - 12 %Mo - 23 %V - 47 %Nb - 49 %Ti - 52 %Al + 189; bahsedilen silindirlerin yüzeylarinin Ra kabaligi 5 mikro m'den daha büyüktür; silindirler arasinda mevcut sivi metalin menisküsü yakininda, hacimle en azindan %60 çelik içinde çözünen bir gazdan mütesekkil bir atil gaz kullanilmaktadir.
