Abstract
The utility model provides a kind of Copper-Aluminum compound casting copper liquid flow control device, comprise stopper, stopper front end is provided with beaver, stopper rear end is connected with connecting rod by screw thread, being provided with external screw thread in the middle part of connecting rod, being also provided with obturating plug, is hollow structure in obturating plug, obturating plug front end is provided with port, and bottom is fixedly connected with filler frame.The tight compression mode of the semi-circular design of the utility model stopper chock plug and the back taper design forming of obturating plug port, the flexible speciality of beaver more enhances this sealing property, guarantees accurate flow control; The direct contact between graphite piece is also effectively avoided in beaver design, prevents the friction consumption of graphite piece, decreases graphite powder impurity, greatly extends the life-span of stopper, improves copper liquid purity; Obturating plug instead of the sintered type copper outlet of integral type crucible furnace, thus has effectively evaded the risk causing body of heater to be scrapped because sintering the wearing and tearing of mouth and destruction, greatly extends the life-span of copper stove, adds the reliability of safety in production.
Description
Technical field
The utility model belongs to continuous casting technical field, relates in particular to a kind of Copper-Aluminum compound casting copper liquid flow control device.
Background technology
At present, in continuous casting field, the flow control technology of copper liquid is a difficult problem, the structure generally adopted and mode are: copper outlet is reserved in copper melting furnace crucible sintering process middle and lower part, and this copper outlet cross sectional shape is the passage of conical shape, adopt ceramic rod to carry out control flow check copper passage, be called stopper, by adjusting the fit clearance flow control of stopper and copper outlet, control the circulation of copper liquid, to ensure the stable in order of casting technique.Under the high temperature conditions, the erosion of copper liquid when the use of stopper will be resisted the strong thermal shock at casting initial stage and cast.Generally, large for the stopper consumption of casting flow control in copper liquid stove, flow control effect is not good.Be in particular in: 1. plug head split pole consumption easy to wear, thus cause poorly sealed, both have impact on normal table casting, frequent replacing causes again the cost of great number, and the leakage occurred when poorly sealed also can cause casting accident to occur.2. copper outlet is through long-time wear damage, and whole melting furnace crucible is scrapped, and increases cost and can produce certain potential safety hazard again.
Summary of the invention
The utility model provides a kind of Copper-Aluminum compound casting copper liquid flow control device, solves the shortcoming that stopper consumption is large, flow control effect is not good in background technology.
The technical solution of the utility model is achieved in that a kind of Copper-Aluminum compound casting copper liquid flow control device, comprise stopper, stopper front end is provided with beaver, stopper rear end is connected with connecting rod by screw thread, being provided with external screw thread in the middle part of connecting rod, being also provided with obturating plug, is hollow structure in obturating plug, obturating plug front end is provided with port, and bottom is fixedly connected with filler frame;
Stopper termination is semicircle;
Described beaver is glass fibre material;
Described obturating plug is graphite piece;
The port of obturating plug is back taper.
The beneficial effects of the utility model are: 1. the tight compression mode of the semi-circular design of stopper chock plug and the back taper design forming of obturating plug port, the flexible speciality of beaver more enhances this sealing property, guarantees accurate flow control.
2. the direct contact between graphite piece is also effectively avoided in beaver design, prevents the friction consumption of graphite piece, decreases graphite powder impurity, greatly extends the life-span of stopper, improves copper liquid purity.
3. obturating plug instead of the sintered type copper outlet of integral type crucible furnace, thus effectively evaded the risk causing body of heater to be scrapped because sintering the wearing and tearing of mouth and destruction, greatly extend the life-span of copper stove, add the reliability of safety in production, and obturating plug is convertibility easily, the adjustable in aperture also can meet the casting of different flow, adapts to the production of plurality of specifications, multi-use, has saved production cost greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Part illustrates: 1, stopper, 2, obturating plug, 3, beaver, 4, connecting rod, 5, graphite piece, 6, filler frame, 7, external screw thread, 8, port, 9, screw thread.
Detailed description of the invention
In order to Comprehension and Implementation better, below in conjunction with accompanying drawing, the utility model is further described: a kind of Copper-Aluminum compound casting copper liquid flow control device, comprise stopper 1, stopper 1 front end is provided with beaver 2, and stopper 1 rear end is connected with connecting rod 4 by screw thread 9, is provided with external screw thread 7 in the middle part of connecting rod 4, also be provided with obturating plug 2, be hollow structure in obturating plug 2, obturating plug 2 front end is provided with port 8, and bottom is fixedly connected with filler frame 6.
Obturating plug graphite piece 5 appearance and size is the column structure of high 60cm, diameter 20cm, obturating plug 2 is designed to hollow structure, in this design, graphite linings thickness is large, and intensity is high, and graphite itself has again certain heat shock resistance, it is truncated cone-shaped structure bottom obturating plug graphite piece 5, height about 20cm landfill in castable refractory, the resistance to 1500 DEG C of high temperature of castable refractory, fire-resistant pouring material periphery is the filler frame 6 of stainless steel, filler frame 6 appearance and size 40X40cm, filler frame 6 is highly 20cm.
It is graphite that stopper 1 designs material, stopper appearance and size is the column solid graphite rod of long 40cm, diameter 8cm, stopper 1 termination is semi-circular design, and put the glass fibre beaver 3 of flexible structure, and beaver 3 is single use part, cheap, by having evaded the loss to graphite stopper to the consumption of beaver 3, glass fibre material has also been a kind of material of resistance to 1300 DEG C of high temperature simultaneously; Stopper end is connected by screw thread 9 with stainless steel connecting rod 4, and connecting rod 4 appearance and size is the long column structure for 120cm, is designed with external screw thread 7 in the middle part of connecting rod 4.
During use, obturating plug 2 is assemblied in copper furnace sidewall, can ensure that the flowing of liquid is carried out gently in unhurried current mode, thus reach stability contorting according to the design that fluid mechanics principle is such.Beaver 3 is installed to stopper 1 head, stopper 1 afterbody is connected by screw thread 9 with connecting rod 4, again connecting rod 4 is assemblied on table by middle part external screw thread 7, is advanced by rotation thus reach the adjustment of stopper and obturating plug fit clearance, thus reaching the effect of stable flow control.
