RU2312739C2 - Apparatus for pouring metal to ingot molds arranged on conveyer - Google Patents

Abstract

FIELD: process for pouring metal to casting molds in conveyer.

SUBSTANCE: apparatus includes barrel like vessel with heater and draining branch pipes arranged over ingot molds. Said ingot molds are arranged in parallel rows between which barrel like vessel is place. When ingot molds of one row approach to pouring place said vessel rotates and metal is fed through branch pipes to ingot molds. After terminating pouring of first row of ingot molds barrel like vessel rotates around it lengthwise axis and metal is fed through branch pipes into ingot molds of other row while ingot molds of first row are changed for empty ones. Barrel like vessel and branch pipes are provided with heaters allowing reduce metal sticking onto constructional members.

EFFECT: simplified design of apparatus, improved efficiency of metal pouring, enhanced quality of cast products.

Description

The invention relates to foundry, in particular to casting molds on a conveyor.

Closest to the proposed technical solution is a device for pouring metal into molds on a conveyor, containing a barrel-shaped container with a heater installed above the molds with the possibility of rotation around its horizontal axis (SU 344924 A B22D 37/00, 07/14/1972).

Its disadvantage is low productivity, metal adhesion to structural elements, low-quality casting surface, the complexity of the device.

The present invention solves the problem of increasing productivity, reducing the buildup of metal on structural elements, simplifying the design, improving the quality of casting.

To achieve this technical result, the device for pouring metal into the molds on the conveyor comprises a barrel-shaped container with a heater mounted above the molds with the possibility of rotation around its horizontal axis, moreover, it is equipped with a furnace with a nozzle, the barrel-shaped container is made with drain pipes and a segmented hole in which is located furnace nozzle, molds are installed in parallel rows, between which a barrel-shaped container is located, while the horizontal axis of the barrel the gas tank is parallel to the rows of molds, in addition, the device is equipped with arch-shaped heaters covering each drain pipe of the barrel-shaped tank, and the tank is equipped with a protective gas supply device to the barrel-shaped tank.

Signs that distinguish the proposed device for pouring metal into the molds on the conveyor from the closest known to it, characterize the device in that it is equipped with a furnace with a nozzle, a barrel-shaped container made with drain pipes and a segmented hole in which the nozzle of the furnace is located, the molds are installed in parallel rows between which the barrel-shaped container is located, while the horizontal axis of the barrel-shaped container is parallel to the rows of molds, in addition, the device is equipped with a arched shaped spanners, covering each drain pipe of the barrel-shaped container, and the container is equipped with a protective gas supply device to the barrel-shaped container.

The device is illustrated by drawings, where in Fig.1 shows a General view of the device, Fig.2 is a section along aa of Fig.1, Fig.3 is a section along bb of Fig.1.

The device for pouring metal into the molds 1, 2 on the conveyor contains a barrel-shaped tank 3 with a heater (not shown in the figures) installed above the molds 1, 2 with the possibility of rotation around its horizontal axis aa using an electric drive 4. The device is equipped with a furnace 5 s pipe 6. A barrel-shaped container 3 is made with drain pipes 7 and a segment-shaped hole 8 in which the pipe 6 of the furnace 5 is located. Molds 1, 2 are installed in parallel rows, between which a barrel-shaped container 3. is located. Horizontal The axis aa of the barrel-shaped container 3 is parallel to the rows of molds 1, 2. The device is equipped with arched heaters 9 covering each drain pipe 7 of the barrel-shaped container 3. In addition, the container 3 is equipped with a protective gas supply device 10 to the barrel-shaped container 3 connected to it flexible, for example corrugated, pipe 11. The segmented hole 8 around the pipe 6 is closed by a shield 12.

The device operates as follows.

When approaching the molds 1, the drive 4 turns the tank 3. The pump is turned on, which feeds the molten metal through the pipe 6 to the tank 3. The metal through the drain pipes 7 flows into the molds. When filling the molds 1, the drive 4 is turned on, the tank 3 rotates around the axis and the metal enters the molds 2 through the drain pipes. When filling the molds 2, the molds 1 are replaced with empty ones, and the process is repeated. The supply of the device with arched heaters 9 eliminates the buildup of metal in the drain pipes 7, which reduces the time for cleaning pipelines and increases productivity.

Providing the device with a barrel-shaped capacity 3 with the possibility of turning it about the axis allows pouring into stationary molds and forming a more even surface of the resulting ingots.

Tests of the prototype of the proposed device was carried out on the casting of magnesium alloys. The fluorine-S and fluorine-2S gas were used as shielding gas. Tests have shown the performance of the design and the implementation of the technical task.
