SU1216611A1 - Charging line of melting furnaces - Google Patents

Description

The invention relates to metallurgy, in particular, equipment for the loading of smelting furnaces, and can be used in foundry shops for smelting, for example, aluminum alloys.

The purpose of the invention is to increase productivity by mechanizing the process of preparing a mixture of scrap and ingots.

The drawing shows the loading line of smelting furnaces ,, - a general view.

The line contains a hopper 1 for scrap with a vibrating feeder 2. A hopper 1 with a vibrating feeder 2 is mounted on a bridge in the movement area of the loading hopper 3, having a movable charge capacity 4. The loading cart 3 is mounted on a rail track 5j along the front of the track. The casting chambers X furnaces 6, Capacity 4 has the ability to move relative to the frame of the loading carriage 3 in the direction of loading oKOii furnaces 6 and is provided with a device in the form of a moving wall with a collider (not shown) to unload the charge from the container 4 to the smelting furnace 6 ,

For the dosed feed of pig material in the loading carriage 3, there is a device consisting of a lifting table 7, a horizontal pig billet 8 and a conveyor 9.

Lifting table 7 contains a cargo platform 10 for installing an unstuck package of 11 pigs and guiding the casing 12, designed to: prevent the package from collapsing at the time of its sequential disassembly along the laying rows by side collision. Cargo platform 10 has the possibility of vertical step movements in a wide range of adjustment,

Art. 8, the actuator 8 is equipped with a pusher 13, which has the possibility of horizontal reciprocating p-transfer movements.

The conveyor 9 is provided with a receiving 14 and a discharge 15 trays and connects the lifting table 7 and the loading car 3 into a single transport system.

Melting furnaces are loaded as follows.

From the scrap storage area, scrap is loaded into the bunker 1 in a known manner, and on the loading platform 10, located in the bottom of the station, 11 ingots are installed by means of a means of transport (1 overhead crane, electric loader, etc.). In this case, the top

A number of 1 € appears. the upper edge of the guide casing 12 of the lifting table 7.

Depending on the grade of the obtained alloy and the composition of the existing scrap, the known way is determined by

the amount of pig material (number of pigs in pieces) required to obtain a mixture of the desired composition. Number of ingots accepted

a multiple of the ingots in the package 11 row and on the line control panel establishes the necessary program for operating the lifting table 7 and the pusher 8 (the number of pushed-off DON pigs for one furnace load). The driven loading trolley, at the operator's command, is fed to the hopper 13; the vibrating feeder 2 is turned on and into the tank 4. The trolley 3 is filled up

CKpgin in the right amount. After loading the scrap, trolley 3 is driven by the operator to the discharge zone of the conveyor 9 under the tray 15; then the device for dosed loading of the pig material, is turned on. In this case, the stacker 8 pushes the upper row of pigs of the bag 11 onto the taller tray 14 through the pusher 13 onto the working conveyor 9 and through the tray 15 is loaded into the tank 4 of the trolley 3. After pushing the upper row of pigs the pusher 13 returns to its original position, the loading platform 10 rises to the height of the pig and the subsequent row of pigs takes the position of the unloaded row. The pusher 13 makes a second working stroke. And the next row of pigs is descriptively supplied to tank 4. This process, depending on a given program, can consist of pushing from one row of bars to overloading the entire bag into tank 4. Loading the required number of pigs, tank 4, the process of preparing the metal mixture by composition to the mass is completed, and at the operator's command the loading carriage 3 is supplied to the w:; avil furnace 6, which requires charging, and stops in front of the loading window of the furnace 6. to the furnace 6, the operator delivers the movement filled with the charge

Capacity 4 into the smelting zone of a 6.packet furnace 11, different in height of the package - Charge with a collider (not shown) of the ingested pigs and the number of rows of the ingots of the tank 4 is loaded into the smelting chamber 11, and the presence of the guide furnace 6 - the housing protects the bag 11 from a razor-proof position. The boot flap is closed at the time of the serial open window. Trolley 3 forming. The proposed line for is distilled. The loading of the furnace is completed.
