Technical field
The present invention relates to a kind of many stoves casting method of aluminium ingot and chute assembly, the casting equipment of enforcement the method.
Background technology
In aluminium electroloysis industry, the casting of aluminium ingot goods is mainly realized by aluminum ingot casting equipment, aluminium ingot casting equipment mainly consists of holding furnace, chute assembly and foundry production line, wherein chute assembly is the catching device between holding furnace and foundry production line, and aluminium liquid is flowed out and entered foundry production line by chute by holding furnace stove eye.
Traditional aluminium ingot casting equipment, it is generally furnace zone one line, a holding furnace connects a foundry production line, for foundry, in order there to be two above holding furnaces in the ，Yi Ge foundry that enhances productivity, correspondingly, every holding furnace all connects a foundry production line, and is completely independently each other.In this case, if will realize every foundry production line, all come into operation, must guarantee that every holding furnace all can enter aluminium liquid in time, mainly because in casting cycle, once occur pausing, be just easy to produce a large amount of aluminium scrap pieces, not only cause waste but also affect production efficiency, and, long if wasted time, temperature in holding furnace can reduce, and also will heat holding furnace, very trouble, but in actual production process, what be but difficult to meet all holding furnaces enters aluminium liquid needs; The more important thing is, due to every holding furnace in use for some time, all want blowing out and scarfing cinder processing carried out in its inside, otherwise affect the normal use of holding furnace, once blowing out, the foundry production line that this holding furnace is corresponding cannot come into operation, and affects aluminium ingot production efficiency.Therefore,, for the aluminum ingot casting equipment that contains two above holding furnaces, the casting mode of stove one line can not play rationally and effectively recycle each holding furnace.
Summary of the invention
The object of this invention is to provide a kind of chute assembly that many stoves casting equipment carries out a multi-thread casting operation in furnace zone of realizing; The present invention simultaneously also provides a kind of casting equipment of this assembly and a kind of many stoves casting method of aluminium ingot of using.
Chute assembly of the present invention adopts following technical scheme: a kind of chute assembly, comprise plural, for being connected to the main chute between corresponding holding furnace stove eye and foundry production line, described each main chute connects in order successively by a chute, being provided with for the aluminium liquid flowing out in corresponding holding furnace is propped up to the flow dividing structure that chute is shunted to corresponding with a chute junction of each main chute, and on a chute, be connected with the adjusting device for regulating a chute gradient to flow to the shunting aluminium liquid changing in a chute.
Described flow dividing structure is the shunting refractory brick being installed in main chute.
Described adjusting device for support be arranged on a chute bottom, along a spaced apart bracing frame of chute length direction, each bracing frame is provided with for adjusting the adjustable supports structure of oneself height.
Casting equipment of the present invention adopts following technical scheme: a kind of casting equipment, comprise two above holding furnaces and with each holding furnace foundry production line one to one, between corresponding holding furnace stove eye and foundry production line, be connected with main chute, described each main chute connects in order successively by a chute, being provided with for the aluminium liquid flowing out in corresponding holding furnace is propped up to the flow dividing structure that chute is shunted to corresponding with a chute junction of each main chute, and on a chute, be connected with the adjusting device for regulating a chute gradient to flow to the shunting aluminium liquid changing in a chute.
Described flow dividing structure is the shunting refractory brick being installed in main chute.
Described adjusting device for support be arranged on a chute bottom, along a spaced apart bracing frame of chute length direction, each bracing frame is provided with for adjusting the adjustable supports structure of oneself height.
Many stoves casting method of aluminium ingot of the present invention adopts following technical scheme: a kind of many stoves casting method of aluminium ingot, the method adopts above-mentioned casting equipment, when one of them holding furnace is during as the supplied upstream equipment of aluminium liquid, according to other main chutes main chute corresponding with the combined upstream stove successively order of connection, by adjusting device, the gradient of each chute is regulated from high to low, the aluminium liquid that the flow dividing structure of main chute flows out combined upstream stove flows to respectively each foundry production line after shunting in order.
Adopt the chute assembly of said structure, because each main chute connects in order successively by a chute, the flow dividing structure of main chute can be realized the shunting of aluminium liquid, and the adjusting device of chute can be guaranteed to shunt aluminium liquid and flows out smoothly, in this case, for any holding furnace, can realize the aluminium liquid flowing out in it and flow to any foundry production line, thereby the production efficiency of guaranteeing aluminium ingot is unaffected, the more important thing is, that can realize that any holding furnace wherein continues enters the operation of aluminium liquid, reduce the aluminium scrap piece generation that casting pauses and causes, simultaneously, for other untapped holding furnaces, can also rationally effectively arrange conventional maintenance operation, thereby realize recycling holding furnace science, saved production cost.
