Abstract
Apparatus separates a thin metal strip produced from a molten metal from a surface of a cooling roll by rapidly solidifying using a single roll method and conveys and guides the separated thin strip downstream. A separation/tensioning/guiding unit is positioned adjacent the cooling roll to separate tension and guide the rapidly solidified thin strip, which unit includes a cooperating doctor blade in pressure contact with the cooling roll. A suction conveyor is provided downstream of the separation/tensioning/guiding unit.
Claims17
An apparatus for separating from a surface of a cooling roll a thin metal strip formed from a molten metal by casting, and for guiding the separated thin strip thereafter, said apparatus comprising:
- an attracting means adjacent to said cooling roll to exert a force on said strip influencing said strip to be separated, tensioned and guided;
- and
- a doctor blade downstream from said attracting means and in contact with said cooling roll and cooperating with said attracting means to effect the separation, tensioning and guiding of said metal strip.
An apparatus for separating from a surface of a cooling roll a thin metal strip solidified from molten metal by casting, and for guiding the separated thin strip to a downstream processing apparatus comprising:
- an attracting means adjacent to said cooling roll to influence separation of the rapidly solidified thin strip from said cooling roll;
- a doctor blade provided in contact with said cooling roll and cooperating with said attracting means to effect said separation, tensioning and guiding;
- and
- a suction conveyor located downstream of said attracting means and doctor blade to further convey the thin strip.
In an apparatus for making metal strip wherein molten metal is solidified by applying it at a selected location to the rotating surface of a cooling roll which is rotated in a given direction, the combination which comprises:
- (a) attracting means positioned adjacent the rotating surface of said cooling roll at an angular location around the circle of rotation of said cooling roll where metal solidification has taken place, said attracting means being operative and effective to loosen solidified metal strip relative to the surface of said cooling roll at said angular location, which is spaced around the angle of rotation of the cooling roll from said location at which the molten metal is applied, and
- (b) a doctor blade positioned against the surface of said cooling roll at an angular location farther around said angle of rotation than is said attracting means, said doctor blade being in a position to cooperate with said attracting means to separate said strip from said cooling roll under the combined influence of said attracting means.
