Abstract

Foreliggende oppfinnelse tilveiebringer en anordning for båndstøping av smeltet metall, omfattende et par av støpevalser RRinnrettet for å motta smeltet metall M langs en horisontal akse, der en vertikal avstand som skiller paret av støpevalser definerer en støpesone; og en elektromagnetisk kantoppdemningsanordning 15 anordnet på hver side av støpesonen som har en induksjonsspole omspunnet rundt en del av en magnetisk struktur for å generere magnetiske kraftlinjer ved påføring av en strøm, der polene på den magnetiske strukturen er anordnet fjernt fra og linjefart med den plane sideveggen til støpevalsene og strømmen genererer magnetiske kraftlinjer vinkelrett på nevnte horisontale akser som holder det smeltede metallet i kontakt med støpevalsene uten nevneverdig å øke temperaturen til det smeltede metallet.The present invention provides a device for strip casting molten metal, comprising a pair of casting rollers RR arranged to receive molten metal M along a horizontal axis, a vertical distance separating the pair of casting rollers defining a casting zone; and an electromagnetic edge damper device 15 disposed on each side of the casting zone having an induction coil wound around a portion of a magnetic structure to generate magnetic lines of force upon application of a current, the poles of the magnetic structure being spaced apart and aligned with the planar sidewall. to the casting rollers and the current generates magnetic lines of force perpendicular to said horizontal axes which hold the molten metal in contact with the casting rollers without appreciably increasing the temperature of the molten metal.
