Abstract
The metal liquid level detecting and controlling unit has one circuit comprising power supply and indication lamp and the circuit has one end connected to the upper end of the liquid level probe and the other end connected to the right end of dummy bar. When metal liquid flows through the duct and the casting mold contacts with the dummy bar, one closed loop is formed. The liquid level probe is insulated from the cantilever and is jacketed by one protective ceramic tube. The liquid level probe is located based on the outlet of casting mold and contacts with the casting mold after the metal liquid inside the crucible reaches the set height. After the metal liquid fills the casting mold completely, one closed loop is formed by the metal liquid, liquid level probe, power supply, indication lamp and dummy bar, and the indication lamp lights. The present invention can control liquid level accurately.
Description
Technical field
The present invention is one of special mechanism of liquid level control in a kind of hot-mold continuous cast technology, belongs to the improvement technology of level controling mechanism in the hot-mold continuous cast technology.
Technical background
Level controling mechanism mainly contains the two poles of the earth that the two poles of the earth measure to be about to liquid-level probe in the circuit and inserts in the crucible simultaneously in the existing hot-mold continuous cast technology, when molten metal contacts simultaneously with the two poles of the earth, circuit meeting UNICOM, indicator lamp lights, and think that liquid level has reached requirement this moment.Its shortcoming is: incorrect if the height and position of electrode is determined, or two electric pole short circuits, even liquid level does not reach requirement, molten metal underfill casting mold, as long as molten metal contacts simultaneously with liquid-level probe two electrodes, indicator lamp all can light, this just creates a deceitful impression, and causes the continuous casting failure.In addition, this mechanism can not fine solution mozzle and the installation deviation problem of casting mold.
A kind of accurate control that can realize that the objective of the invention is to overcome above-mentioned shortcoming and provide to liquid level in the hot-mold continuous cast technology, the hot-mold continuous cast level controling mechanism that can prevent and avoid many accidents to take place again.
Summary of the invention
The present invention is a kind of metal liquid level detecting and controlling unit that is used for hot-mold continuous cast, molten metal flows in the casting mold through mozzle, carry out dummy ingot by dummy bar, the upper end of liquid level control rod is installed on the right-hand member of cantilever, the bottom of liquid level control rod is inserted in the molten metal, the upper end of level probe is installed on the right-hand member of cantilever, its end top, lower end contacts with molten metal, the cantilever left end is installed on the column, be carved with scale on the column, the left end of cantilever is installed on the screw mandrel, pass through motor, magnetic powder cluth or handle drives screw mandrel rotate, and drive cantilever, the liquid level control rod moves up and down, and it is characterized in that: by power supply, one end of the circuit that indicator lamp is formed links to each other with the upper end of level probe, the other end links to each other with the right-hand member of dummy bar, at metal liquid stream through mozzle, casting mold forms a closed circuit loop when contacting with dummy bar.Level probe and cantilever insulation are with earthenware protection outside.Level probe is that benchmark positions with the casting mold exit.
The present invention is the benchmark of liquid level control probe location with the casting mold exit, and when the molten metal in the crucible reached the height of setting, level probe can contact with it.After molten metal had been full of casting mold fully, molten metal, level probe, power supply, indicator lamp and dummy bar formed a loop, and indicator lamp lights, and can realize accurately control to liquid level like this.
Description of drawings
Fig. 1 is the structure chart of apparatus of the present invention.
Specific implementation
As shown in Figure 1, the inventive system comprises crucible 14, mozzle 16, dummy bar 1, liquid level control rod 9, level probe 4, power supply 3, indicator lamp 2, molten metal 15, column 8, the lifting of liquid level control rod and detent mechanism and comprise cantilever 6, screw mandrel 10, magnetic powder cluth 13, motor 12, handle 11, scale 7.Wherein level probe 4 is fixed on the cantilever 5, can adjust height up and down, and insulate with cantilever 5, is with earthenware protection outside.Power supply 3 is a 24V direct current safety power supply.When the molten metal in the crucible 14 15 reached the height that needs, level probe 4 is contact with it, and molten metal 15, level probe 4, power supply 3, indicator lamp 2 and dummy bar 1 form a loop, and indicator lamp lights, and this moment, continuous casting can begin.The loop of this moment only molten metal entered casting mold and with can UNICOM after dummy bar contacts, in addition, the location of level probe 4 is to be benchmark with the casting mold exit, be not junction with mozzle and crucible be benchmark, can guarantee that like this molten metal in the crucible can really be full of casting mold, molten metal can not be full of the situation of casting mold fully in the time of can avoiding simultaneously occurring shown in the figure dotted line because of installation deviation.
The front end of motor 12 is equipped with a cycloid speed reducer, speed ratio is up to 1283: 1, and the pitch of screw mandrel is 6mm, and motor speed is 1500rpm, the speed that the liquid level control rod moves down automatically is (1500/1283) * 67mm/min, and liquid level steadily and can keep liquid level at any time under this speed.In the starting stage, because the molten metal liquid level is from requiring distance bigger, it is lower to press down speed automatically by motor 12, presses down so can carry out quick manual by handle 11, when indicator lamp lights for the first time, manual mode can be switched to automatic mode and carry out slow and stable pressing down.When accidents such as leakage occurring, automatic mode can be switched to manual mode again and carry out fast lifting.In addition, manual mode also can be realized by a fast speed motor in the whole process.
The present invention is the benchmark of liquid level control probe location with the casting mold exit, when the molten metal in the crucible 14 15 reaches the height of setting, level probe 4 is contact with it, after molten metal has been full of casting mold really fully, molten metal 15, level probe 4, power supply 3, indicator lamp 2 and dummy bar 1 form a loop, indicator lamp lights, and can realize accurately control to the liquid level in the hot-mold continuous cast technology.In addition, the manual mode of liquid level control rod elevating mechanism and automatic mode can well satisfy the requirement in the hot-mold continuous cast technical process; Scale on the column can be with reference to the liquid level of determining molten metal in the crucible, and unlikely generation molten metal overflows the phenomenon of crucible.
