Furthermore, the cross-sectional shape of the casting can be determined by a mold, and a casting having a complicated cross-sectional shape can be continuously cast. The hot type continuous casting may be classified into horizontal hot type continuous casting, vertical pull-down hot type continuous casting, vertical pull-up hot type continuous casting, and the like according to the apparatus.

When the present application is used for liquid replenishment of a hot type continuous casting apparatus, the present application has advantageous effects, compared with the prior art, that (1) by setting the conductive float 21 and the conductive rod 22 which can be brought close to each other and electrically contacted to a liquid level switch, wherein the conductive floater 21 can ascend and descend along with the ascending and descending of the liquid level, the closing and the opening of the liquid level switch are controlled by utilizing the ascending and descending of the liquid level, thereby realizing the electrification and disconnection of the selection circuit, the disconnection and electrification of the work, further realizing the ascending and descending of the plug rod 5, further realizing the opening and closing of the fluid infusion hole, thereby realizing the timely liquid supplement and disconnection liquid supplement to the second liquid cavity, not only ensuring the continuous casting operation and being difficult to cause the problem of the cross section loss of the casting, the purpose of controlling the liquid level height of the second liquid cavity is achieved, the pressure of the molten metal on the cross section of the casting mold is reduced, and the problem of leakage is not easy to occur; (2) compared with the traditional liquid level detection rod 2 and the liquid level of the metal liquid as the conductive contact, the liquid level detection rod can avoid the problem that the metal liquid is adhered to the conductive contact, improve the detection sensitivity of the liquid level detection rod 2, and is beneficial to timely supplementing and disconnecting fluid supplementation; (3) the metal liquid on the upper layer and the lower layer of the box body 1 are separated by the partition plate 11, so that the gravity of all the metal liquid in the box body 1 can be prevented from acting on the cross section of the casting mold positioned on the lower part, the pressure of the metal liquid on the cross section of the casting mold is reduced, and the problem of leakage is not easy to occur.
Further, in the present embodiment, as shown in fig. 3, the circuit a in fig. 3 is a selection circuit, and the circuit b is an operation circuit. The controller comprises a relay 3 and a liquid supplementing control module; the liquid level switch is connected with the relay 3 in series to form a relay control module, and the relay control module is connected with a normally open switch of the relay 3 in parallel to form a selection circuit; the liquid supplementing control module is connected with a normally closed switch of the relay 3 in series to form a working circuit. The relay 4 is a transfer type (Z type) relay, that is, a contact group type relay. The contact group of the relay 4 has three contacts, namely a movable contact in the middle and a fixed contact at the upper part and the lower part. When the coil is not electrified, the movable contact and the first fixed contact are disconnected, and the movable contact and the second fixed contact are closed; after the coil is electrified, the movable contact moves, so that the movable contact is in a closed state (namely the movable contact is closed with the first fixed contact) when being opened originally, and is in an open state (namely the movable contact is disconnected with the second fixed contact) when being closed originally, and the aim of conversion is fulfilled. The switching relay is adopted as the main component of the selection circuit, and has the advantages of quick action and stable work.
Further, in this embodiment, the fluid infusion control module is specifically an electromagnet 4. The electromagnet 4 can be a common electromagnet, and the common electromagnet can obtain magnetism after being electrified. And the top end of the plug rod 5 is inlaid with a magnet or a ferromagnetic block, when the working circuit is electrified, the electromagnet 4 can obtain magnetism, and the plug rod 5 is attracted to move upwards and does not block the fluid infusion hole any more; when the working circuit is broken, the electromagnet 4 loses magnetism, and the plug rod 5 moves downwards under the action of gravity to block the liquid replenishing hole again.
Further, in the present embodiment, the electromagnet 4 is most preferably a push-pull electromagnet, and the movable iron core of the electromagnet 4 is connected to the plunger 5. The coil, the movable iron core, the static iron core, the power controller and other accessories form the push-pull electromagnet. The leakage flux principle of the spiral pipe is utilized, the movable iron core and the static iron core of the electromagnet 4 are attracted in a long distance, the linear reciprocating motion of the plug rod 5 can be realized, the gap plugging operation of the plug rod 5 to the liquid supplementing hole can be met, the gap liquid supplementing of the second liquid cavity is realized, the requirement of the automatic liquid supplementing device for controlling the liquid level of the second liquid cavity is met, the pressure of the conductive liquid to the cross section of the casting mold is low all the time, and the leakage problem is not easy to occur.
Further, in this embodiment, the fluid infusion control module is specifically an electric telescopic rod, and the electric telescopic rod is connected with the plug rod 5. When the liquid level in the second liquid cavity is too low, the selection circuit is switched off, the working circuit is electrified, the electric telescopic rod is contracted, the plug rod 5 is lifted upwards, and the first liquid cavity supplies liquid to the second liquid cavity through the liquid supply hole; when the liquid level in the second liquid cavity is too low, the selection circuit is electrified, the working circuit is disconnected, and the electric telescopic rod can recover the original length, so that the liquid replenishing hole is blocked by the plug rod 5, and the first liquid cavity stops replenishing liquid for the second liquid cavity.
More specifically, as shown in fig. 3, the circuit a in fig. 3 is a selection circuit, and the circuit b is a working circuit. The selection circuit adopts a 6V direct current power supply, and the working circuit adopts a 24V direct current power supply. Because the selection circuit is mainly used for realizing the disconnection or the closure of the normally open switch of the relay 3, and the voltage required by the selection circuit is very low, a 6V direct-current power supply is adopted; and electro-magnet 4 (or electric telescopic handle) are used for controlling cock stem 5 and reciprocate, need convert the kinetic energy of cock stem 5 into with the electric energy, and the voltage of working circuit directly influences the voltage of electro-magnet 4 (or electric telescopic handle), and then influences electro-magnet 4 (or electric telescopic handle) to the drive effect of cock stem 5, so adopt 24V DC power supply, can satisfy the electro-magnet 4 (or electric telescopic handle) after the circular telegram to the drive effect of cock stem 5. As shown in fig. 3, both the selection circuit and the operation circuit are provided with manual switches. The selection circuit is a master switch, and the manual switch can be conveniently set for timely opening or closing the circuit for the worker to select to stop or start the operation according to actual needs.
Further, in the present embodiment, as shown in fig. 1, the tank 1 is made of a conductive material, and the tank 1 is a second access end of the liquid level switch. Because the liquid level switch is composed of the conductive rod 22, the conductive float 21 and the conductive liquid in the second liquid cavity, the first end of the liquid level switch is conductively connected with the outside through the second end of the conductive rod 22, and the second end of the liquid level switch is conductively connected with the outside through the conductive liquid in the second liquid cavity, but because the conductive liquid is difficult to install a wire, the liquid can be used as the conductive liquid and the conductive medium outside through the box body 1, as shown in fig. 1, that is, the outer wall of the box body 1 is connected with a wire to be communicated with a circuit, so that the conductive rod 22, the conductive float 21, the conductive liquid in the second liquid cavity and the conductive box body 1 form the liquid level switch, and the power-on state of the liquid level switch is controlled by whether the second end of the conductive rod 22 and the bottom wall of the conductive float 21 are in electrical contact, and whether the second end of the conductive rod 22 and. The case 1 is made of a conductive substance, and may be metal, graphite, graphene, or the like. Wherein the box body 1 can be a crucible, a casting furnace and other casting devices in the casting operation, and the most preferable choice of the box body 1 is a graphite crucible which has good electrical conductivity, high temperature resistance and the like.
Further, in the present embodiment, as shown in fig. 2, the second end of the conductive rod 22 is provided with a connection terminal 25, and the connection terminal is a first connection end of the liquid level switch. Since the second end of the conductive rod 22 cannot be directly connected to an external circuit through a wire, the connection between the conductive rod 22 and the external circuit can be facilitated by burying the connection terminal 25 in the second end of the conductive rod 22.
Further, in the present embodiment, as shown in fig. 2, the outer wall of the conductive rod 22 is sleeved with an insulating sleeve 24. Because the conducting rod 22 if electrically conducts with the conducting liquid in first sap cavity, can lead to liquid level detection stick 2 to lose the detection function to the liquid level height in second sap cavity, in order to avoid liquid level detection stick 2 to electrically conduct with the conducting liquid in first sap cavity, need overlap at the outer wall of conducting rod 22 and be equipped with insulating cover 24, insulating cover 24 is made by high temperature resistant insulating material, and insulating cover 24 can adopt high temperature resistant pottery to make.
Further, in this embodiment, as shown in fig. 2, a first end of the conductive rod 22 is provided with a slip-off preventing ring 23, and the slip-off preventing ring 23 can limit the conductive float 21, so that the conductive float 21 can only move up and down and cannot be disengaged from the conductive rod 22. When the stop of the casting operation is required, if the anti-slip ring 23 is not arranged, the conductive floater 21 can be lowered to the bottom wall of the box body 1 along with the liquid level, the conductive floater 21 cannot provide liquid level detection for the next casting operation, and the anti-slip ring 23 can ensure that the liquid level detection rod 2 can be continuously used.
More specifically, referring to fig. 2, the conductive float 21 is assembled by sealing an upper case having a through hole for allowing the conductive rod 22 to pass therethrough and having a width smaller than that of the anti-slip ring 23, and a bottom plate made of graphite, the conductive rod 22 being made of graphite, so as to satisfy the requirement that the conductive rod 22 and the bottom plate can be brought close to each other and electrically contacted.
Further, in the present embodiment, as shown in fig. 3, an indicator lamp 6 and a slide rheostat are connected in series to the normally open switch of the relay 3, and the indicator lamp 6 is used for displaying the power-on operation conditions of the operating circuit and the selection circuit.
