BUNKER ESTKADL BEACH FURNACE

The utility model relates to metallurgy, to equipment

for loading melting furnaces, and in particular, to installations for dosing and supplying alloying and slag-forming materials of the Ladle Furnace complex.

Known bunker racks used at NTMK N-Tagil, the prospectus of the company FUCHS-SISTEMTECHNIK, as well as the bunker racks of the blast furnace according to AS 1425423. On these installations for

transportation and supply of material used tape

conveyors. As a result, during transfer and transportation, losses of expensive material occur.

As a prototype adopted hopper rack C13, which contains devices for dispensing, weighing and

transportation of alloying and slag-forming additives made in the form of 3 horizontal-weight conveyors and 2 nak-

pubic. Prior to filling the bucket with expensive materials,

weighed with high accuracy, pour 2 times, which inevitably leads to loss of material. Also in closed

Conveyor belts accumulate a large amount of dust and

dirt, part of the legir ttsih and slag-forming additives settles, and

when loading additives into the oven, the tape burns out.

These shortcomings stimulated the search for new technical solutions.

The objective of the proposed Utility model is to increase the reliability of obtaining metahs with specified properties, due to the complete filling without loss of alloying additives, simplifying the design of the flyover, and supporting the metal consumption of its manufacture.

According to the utility model, the devices for transportation and weighing are made in the form of a weight trolley and a skip elevator, and the dosing device in the form of a vibratory chute.

The proposed bunker overpass is illustrated by drawings, where Fig. 1 shows a schematic diagram of the supply of materials, Fig. 2 is a section of UEg / 1 in Fig. 1.

The bunker overpass consists directly of metal structures, bins 1, vibratory chutes 2, a weight trolley 3 with a shutter 4 and built-in load cells, a rail track 5,

skip hoist 6, intermediate unloading funnel 7 and a device for uniform feeding of the furnace material made in the form of a gutter 8. Filling the hoppers comes from containers 9, which are installed on the hopper using a crane. The overpass works as follows. The program is set

loading the weighing trolley 3. The material from the bins 1 using a vibratory chute 2 is fed into the hopper of the weighing trolley 3. After collecting the dose, the trolley 3 moves along the rail 5 to the next position or to the place of the filling E skip 6. The filling is carried out with

using the sector shutter $ ,. After receiving the dose, the skip transfers the material through the intermediate discharge funnel 7 and the chute 8 to

In the window of the Bucket Furnace, the HVAC system is lowered to its original position and the cycle repeats.

Thus, the exact dosage and supply of alloying and slzobrazuyuschie Dr $ avok E complex ladle furnace, which allows to obtain high-quality steel with desired properties.
