Description

Technology area

The invention relates to metallurgy and can be used for pouring liquid metal from a transport ladle into a receiving container, such as a mold or a pouring casting conveyor.

State of the art

At present, domestic aluminum plants use a tilting device for pouring liquid aluminum into molds, on which a transport ladle is installed. The device is equipped with a tilt drive in the form of a gearbox with an electric motor or a hydraulic cylinder. The disadvantage of this technical solution is that an additional device necessary for tilting the ladle is necessarily involved in the process of metal overflow.

Known device for turning the bucket (and.with. No. 880627, B22D 41/06, publ. 1979). This device does not require the use of a workshop gantry crane to perform the overflow operation, since it has its own autonomous gantry mounted on a monorail trolley. The portal is equipped with a device for turning the bucket in the form of a gearbox with an electric motor. The disadvantage of this design is the presence of a complex gearbox consisting of a worm, gears and a cam clutch, as well as an electric motor.

Known complex for casting liquid metal (RF patent No. 2058851, B22D 41/06, publ. 04/27/1996), containing a transport ladle having a pair of trunnions and a lifting beam, a support device and a stop, characterized in that the support device is a base and two racks, the stop is made in the form of a hinge support device installed on two racks, while the complex is equipped with a pair of pivot cheeks suspended from the hinge and having an oblique groove for the bucket trunnions, pushers hingedly attached to the lower part of the cheeks, a connecting rod, hingedly attached to the support device , and a reciprocating drive having a plunger installed in the bearing for rotation on the base of the support device, and the pushers are movably connected by means of an axis to the connecting rod and the plunger. The disadvantage of this design is the presence of a complex supporting device with hinges and a pusher.

Disclosure of invention

The objective of the invention is to exclude the use of additional tilt devices when pouring metal into receiving tanks from ladles with their own swing drive.

The technical result of the invention is to reduce the height of the fall of the metal and the elimination of metal spatter, simplification of the design.

The technical result is achieved due to the fact that in the device for pouring liquid metal, containing a frame, a transport ladle with a pouring nose, a swing drive and a lifting beam, it is new that it contains a metal path consisting of an arcuate chute that turns into a horizontal chute, connected with a storage bowl equipped with an outlet taphole for further pouring liquid metal, while the frame is equipped with cradles for placing the lifting beam of the bucket, the transport bucket is installed on the frame with the lower part of the beam supported on it, and the drive for its rotation contains a gear motor that allows the transport ladle with the pouring nose towards the arcuate tray.

The invention is complemented by particular features. Thus, the metal path and the storage bowl are lined with refractory material.

The device for pouring liquid metal consists of a frame 1, designed to install a transport bucket 2 with liquid metal on it, a metal path consisting of an arcuate tray 3, turning into a horizontal tray 4, a storage bowl 5, which has an adjustable support 6 and a platform for maintenance 23. The metal path and the storage bowl 5 are lined with refractory material 7 for thermal insulation. The collecting bowl 5 is equipped with an outlet tap 8, an adjusting lance 9 and a drain chute 10, which transfers the metal to the dispensing chute 11, which can rotate on the axis 12 and move along the guide support 13 for pouring liquid metal into the receiving containers 14.

Device operation

The transport bucket 2 with liquid metal is installed using an overhead crane (not shown), which has the appropriate lifting capacity, on the frame 1, which has cradles 16 to accommodate the lifting beam of the bucket and limiting the movement of the transport bucket 2 on the frame 1. The transport bucket 2 rests on the frame 1 of the lower part of the traverse 15. Next, the crane hook is disengaged with the eye 17 of the traverse 15 of the transport bucket 2.

Before pouring metal from the transport bucket 2 into the metal path, it is necessary to remove the latch 18 from engagement with the rod 19 of the traverse 15.

Having turned on the electric drive 20, the transport bucket 2 is turned with the pouring nose 21 towards the metal path and the safe filling of the storage bowl 5 with liquid metal is controlled. When filling the storage bowl 5, the operator, using the adjusting lance 9, controls the required metal consumption in the dispensing tray 11 and pours the metal into the receiving containers 14, turning the dispensing tray 11 sequentially from one receiving container 14 to another. To prevent metal spillage between the receiving containers, gate 22 is used, which is equipped with the 11 dispensing chute to shut off the metal flow from the 11 dispensing chute to the 14 receiving tanks.

After pouring and returning the transport bucket 2 to the vertical position, it is necessary to secure the rod 19 with the lock 18. The transport bucket 2 is returned by an overhead crane to a trolley (not shown).

After cooling the liquid metal in the receiving tank 14, the resulting ingots are removed by a crane or other lifting device for special devices that are equipped with the receiving tank 14.

The advantages of the proposed technical solution:

- the proposed design of the device for pouring liquid metal does not require additional drive mechanisms for pouring metal into receiving tanks, except for the gear motor available on the transport ladle;

- the device can be moved to any place convenient for service;

- a device for pouring liquid metal from a transport ladle allows pouring liquid metal into such receiving tanks as molds of the SOW type or onto a pouring casting conveyor.
