Abstract

FIELD: metallurgy, possibly semicountinuous casting of ingots, mainly of aluminum alloys. SUBSTANCE: casting machine includes water distributing frame having two compartments. First compartment is communicated with water supply system through automatic regulating organ; second compartment - due to bypassing it. First compartment through joining units is connected with cavity of upper cooling zone of mold; second compartment is connected with cavity of lower cooling zone of mold. At casting to electromagnetic mold water is supplied into its upper and lower cooling zones. Water flowrate corresponding to faces of mold is controlled by means of locking-regulating members of joining units. At casting to sliding type mold, locking and regulating members provide disconnection of second compartment from joining units and water is fed only to upper cooling zone. EFFECT: enlarged technological possibilities of casting machine. 7 dwg

Description

 The invention relates to the field of metallurgy, in particular to the designs of foundry machines for semi-continuous casting of ingots, mainly from aluminum alloys.

 Alussuisse casting machines are widely known, the design of which allows ingots to be cast only into an electromagnetic mold and excludes the possibility of casting ingots into a slip mold.

 Known foundry machines of the Spanish company "INESPAL" (see drawing 900048), containing a casting platform, a drive for moving it, a water distribution frame, the cavity of which is connected to the water supply system through an automatic regulating body. The water distribution frame has elements for docking with slip molds for casting flat ingots - a prototype. A drawback of the designs of these foundry machines is the impossibility of casting ingots on it into an electromagnetic mold.

 The technical essence of the technical solution proposed for consideration is to expand the capabilities of foundry machines from the point of view of creating conditions for casting ingots into them both in a slip mold and in an electromagnetic mold, depending on the needs of production.

 The technical result in the proposed technical solution is achieved by the fact that the water distribution frame of the casting machine is made in the form of two compartments, the first of which is connected to the water supply system through an automatic regulating body, and the second mantle is connected to the water supply system bypassing the regulatory body. The first compartment of the water distribution frame is connected through docking blocks to the cavity of the upper cooling belt of the electromagnetic mold or to the working cavities of the slip mold. The second compartment is connected via docking blocks to the cavity of the lower cooling belt of the electromagnetic mold. Docking units are equipped with locking and regulating elements for regulating the flow of water along the edges of the molds.

 The device comprises a drive 1 for moving the casting platform 4, a water distribution frame 2, a casting tray 3 and guides 5 for the platform 4 (see Fig. 1).

 The water distribution frame 2 is made of compartments 6 and 7 (see figure 2, 3). The first compartment 6 is connected to the water supply system through the pipe 8, the automatic regulating body 9, the flow meter 10 and the hydraulic valve 11, and the second compartment 7 is connected to the water supply system through the pipe 12 bypassing the automatic regulating body 9 (see Fig. 2). To increase the compactness of the water distribution frame 2, the second compartment 7 is made inside the first compartment 6. The water distribution frame 2 is equipped with docking units 13 (see Fig. 3), the planes of which are connected to the compartments 6 and through the locking and adjusting elements 17 (see Fig. 5) . In FIG. 4, 5 shows an example of the installation of electromagnetic molds 14 on the water distribution frame 2 of the casting machine and the connection of the cavities of the upper cooling zone 15 and the lower cooling zone 16 with compartments 6 and 7, respectively. 6, 7 shows an example of the installation of the mold 18 and the connection of the working cavities of the mold with compartment 6 of the water distribution frame 2.

 The proposed device is as follows.

 In the initial position, electromagnetic crystallizers 14 are installed on the water distribution frame 2, with the help of locking and regulating elements 17, the uniform water flow is adjusted along the large and small faces of the mold 14 for a certain size of the ingots, the casting platform 4 is raised to the upper position (see figure 1) and seeds (not conventionally shown) are introduced into the zone of mold-forming inductors of crystallizers. The hydraulic valve 11 is turned on and water enters through a flowmeter 10, an automatic regulator 9, a pipe 8 into the first compartment 6 and then through the docking units 13 into the cavity of the upper cooling belt 15, and also through the pipe 12 into the second compartment 7 of the water distribution frame 2 and then through the docking blocks 13 into the cavity of the lower cooling zone 16.

 The seeds are fed with liquid metal through the casting tray 3, and upon reaching a certain level of metal, drive 1 is turned on.

 The foundry platform 4, along with the seeds, begins to move along the guides 5 with a speed that increases according to a certain program to the working one, while the water is supplied to the cavity of the upper cooling zone 15 through an automatic regulating body 9 with a variable flow rate that increases depending on the increase in the speed of movement of the platform 4 . Upon reaching the operating speed of the platform 4, the flow of water to the upper cooling zone 15 is maintained constant by means of an automatic adjustable body 9 Onceanu casting. The flow of water to the lower cooling zone 16 remains constant from the beginning to the end of the casting. After casting the ingots of the required length, they are removed from the linear platform 4, the casting machine is transferred to its original position, and then the cycle repeats.

 When casting ingots into the slip mold 18, cooling water is supplied from the first compartment 6 through the docking units 13. The locking and regulating elements connecting the compartment 7 to the docking units 13 are in the closed position.

 The application of the proposed device in production will allow casting of ingots both in a slip mold and in an electromagnetic mold on one casting machine.
