Abstract
A casting system for casting and rolling plate band is composed of a static furnace and a molten metal delivering unit. It features that the top of said static furnace is enclosed, the molten metal is pumped to the feeder by a molten metal pump, and it is possible to use a protecting gas system for the metal easy to be oxidized.
Description
Technical field the invention belongs to the metal material processing technology, particularly the strip rolling casting technology.
Background technology strip rolling casting technology be molten metal through casting system, have the casting roll gap gap of circulation cooling effect by a pair of inside, draw casting band embryo after the crystallization and freezing distortion.The strip casting is shaped and has that technological process is short, energy-conservation, lumber recovery is high, equipment investment is few, the board quality advantages of higher.
In the strip rolling casting technology, the metal flow control of casting system is a guardian technique, it directly influences the quality of strip moulding, " strip casting theory and technology " (work such as Sun Binyu, metallurgical industry publishing house in October, 2002 front page) in the Article " double-roll type strip casting and rolling installation ", two kinds of principal modes of the metal flow of strip casting system for continuously casting and rolling control is both at home and abroad at present disclosed: 1, the highly stable device of lever metal bath surface.2, the highly stable device of floating-type metal bath surface.
The core of said method is to control the flow that flows to casting roll gap molten metal by the metal bath surface height of preceding case in the control casting system, the subject matter that this class strip casting system for continuously casting and rolling exists is: 1, they are all formed by leaving standstill stove, chute, preceding case three parts, the metal bath surface height of case before regulating by the intermediary agency between chute and the preceding case (lever or cursory), its long flow path, complex structure; 2, the metal bath surface elevation control mechanism therefor of its preceding case is that liquid level difference by chute and preceding case opens and closes, so the flow of this class casting system is unbalanced, and the error of flow directly influences the casting quality; 3, leave standstill stove, chute and preceding case and be unenclosed construction, molten metal is easily oxidized, is unsuitable for the casting (as magnesium alloy etc.) of the metal of easy oxidizing fire especially.
In the prior art, chute and preceding case significant feature are to provide stable, balanced molten metal for feed mouth device (being lip).
Summary of the invention the objective of the invention is to design a kind of new closed strip casting system for continuously casting and rolling, shortens production procedure, keeps stable molten metal flow, and makes the metal of its energy commute oxidizing fire carry out casting, thereby produces the casting strip of high-quality.
The total technical scheme of the present invention is: chute and preceding case being saved, and carry out closed transformation to leaving standstill stove, is that feed mouth device (being lip) provides stable, balanced molten metal by liquid metal pump directly.That is to say directly motlten metal injected the enclosed stove that leaves standstill, by liquid metal pump with liquid metal through cross gate, feed mouth device, casting roller, casting becomes metal plate and belt.
Specifically, the present invention is achieved by the following technical solutions.Promptly add a bell 9 at the top of leaving standstill stove and will leave standstill the stove sealing, and in the bottom of leaving standstill stove one liquid metal pump is installed, liquid metal pump can be the mechanical type metal pump, also can be the electromagnetic type metal pump.
Particularly when the metal of casting was the metal of easy oxidizing fire, the present invention can also add a protective gas system 10 at the top of leaving standstill stove, so that protective gas to be provided.
The course of work of the present invention is: the good molten metal alloy of refining in the smelting furnace is injected leave standstill stove, and processing such as in leaving standstill stove, purify, keep the required temperature of casting-rolling technology, again by leave standstill in the stove liquid metal pump by certain pressure and flow continuous with liquid metal, pipeline (running channel), feed mouth device (being lip) by sealing are transported to roll casting district, and casting becomes metal plate and belt continuously.
When the metal of casting is the metal of easy oxidizing fire, can in leaving standstill stove, provide protective gas by protective gas system 10.
The present invention can reach following effect:
1, in casting shaping flow process, can save chute, preceding case, therefore shorten technological process;
2, use metal pump can adjust pressure and flow that liquid metal flows easily, make the flow of molten metal more accurate;
3, this casting system is closed, can reduce the oxidation of molten metal, and can make the incendive liquid metal of easy oxidation (as magnesium alloy etc.) be in and realize under the protective gas that casting is shaped;
4, handle molten metal in the stove, high insulating effect, energy-conservation closed leaving standstill.
Appended drawings is a decomposing schematic representation of the present invention
Accompanying drawing 1 is the schematic diagram of a kind of embodiment of the present invention.1 for leaving standstill body of heater among the figure, and 2 is insulating layer of furnace body, and 3 is crucible, and 4 is metal paste, and 5 is the mechanical type metal pump, and 6 is cross gate, and 7 is lip, and 8 are the casting roller, and 9 is bell, and 10 is the protective gas system.
Accompanying drawing 2 is schematic diagrames of another kind of embodiment of the present invention.1 for leaving standstill body of heater among the figure, and 2 is insulating layer of furnace body, and 3 is crucible, and 4 is metal paste, and 5 is the electromagnetic type metal pump, and 6 is cross gate, and 7 is lip, and 8 are the casting roller, and 9 is bell, and 10 is the protective gas system.
Specific embodiment the present invention can be described further by following examples.
Embodiment 1: accompanying drawing 1 is the schematic diagram of one embodiment of the present of invention.Strip casting system for continuously casting and rolling in the present embodiment is by leaving standstill body of heater 1, insulating layer of furnace body 2, crucible 3, mechanical type metal pump 5; cross gate 6, lip 7, casting roller 8, bell 9; protective gas system 10 forms, and in the present embodiment, employed liquid metal pump is a mechanical type metal pump 5.
Technological process is at first bell 9 to be opened; in crucible 3, inject metal paste 4; after the metal paste processing; sealing bell 9; in crucible 3, feed protective gas by protective gas system 10 again, carrying out after casting prepares, by the mechanical type metal pump by constant compression force and flow with the metal paste 4 in the crucible 3; be transported to lip 7 through cross gate 6, through casting roller 8 the metal casting become metal plate and belt at last.
Embodiment 2: accompanying drawing 2 is the schematic diagram of an alternative embodiment of the invention.As shown in Figure 2, strip casting system for continuously casting and rolling in the present embodiment and technological process and embodiment 1 all fours, just in the present embodiment, employed liquid metal pump is an electromagnetic type metal pump 5.
