Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pig iron machine for casting hot metal or ferroalloy produced in a melting furnace such as a blast furnace or an electric furnace.

[0002]

[Prior Art]

 The pig iron machine uses hot metal or ferroalloy as a hot metal.The hot metal is cast from a melting furnace or hot metal ladle into a running mold by an endless chain, cooled and solidified in the running mold to form the hot metal, and the mold is a mold conveyor. When it reaches the upper end and flips over, the mold pig iron is allowed to fall freely from the mold and collected in the mold pig receiving hopper. However, the mold iron that has been cooled and solidified does not fall from the mold when the mold comes to the upper end of the mold conveyor and reverses because the mold burns into the mold due to high temperature or bites, etc. Then, after returning to the return run and falling, it is no longer possible to collect it in the die pig hopper.

For this reason, conventionally, in order to collect die pig iron (hereinafter referred to as pig iron) that falls during return traveling, a pig iron chute 17 is provided below the mold conveyor 1 as shown in FIG. The litter was collected in the collection bag 18. The pig iron collected in the collection bag 18 is transported to a predetermined yard and stored together with the pig iron collected in the pig iron receiving hopper.

[0004]

[Problems to be solved by the device]

 In addition to the problem that these pig irons must be collected in a bad environment such as dust or high temperature, in the operation of changing varieties, timely collection is necessary in order to prevent mixing of different materials, and in some cases Had problems such as having to interrupt the pig iron work. That is, the conventional cast iron machine has to install a chute for collecting pig iron and collect the pig iron in a collecting bag, and then convey the bag to a predetermined yard. In the case of the existing pig iron, since Fe-Mn and Si-Mn are alternately cast at a pitch of 2 to 3 hours, there is a possibility that different metals are mixed in the same recovery bag. In addition, even if a switchable chute is used to switch the chute for each pig iron, the work load of transporting the pig iron collected in the collection bag to a predetermined yard cannot be reduced.

The present invention has been made in order to solve such a problem, and by arranging a pan conveyer below the mold conveyor, the pig iron and the pig iron are simultaneously captured in the pig iron receiving hopper. An object is to provide a casting pig machine that can be assembled.

[0006]

[Means for Solving the Problems]

 The gist of the invention is to use an endless chain having a plurality of molds, a mold conveyor including a device for driving the endless chain, and a casting pig iron machine having a pig iron receiving hopper. It is provided above the opening of the hopper, and the upper end of the pan conveyor that runs in the same direction as the mold conveyor is aligned above the chute provided on the side surface of the mold piggy hopper and below the mold conveyor. It is a pig iron machine with conveyors installed side by side.

[0007]

[Action]

 As shown in FIG. 1, the casting pig iron machine of the present invention has a mold pigeon receiving hopper 3 below the upper end 2 of the mold conveyor 1 and a pan conveyer running below the mold conveyor 1 in the same direction as the mold conveyor 1. The pan conveyor 4 is arranged below the mold conveyer 1 so that the upper end 5 of the mold 4 is aligned with the upper side of the chute 6 provided on the side surface of the mold piggy hopper 3. The mold pigeon receiving hopper 3 is assumed to be capable of traveling on rails, and a damper 8 is provided at the bottom thereof.

In operation, when hot metal is cast into a mold (not shown) running by an endless chain and cooled and solidified in the running mold to form hot metal, when the mold reaches the upper end 2 of the mold conveyor 1 and is inverted. Then, the mold pig iron falls freely from the mold and is collected in the mold pig receiving hopper 3 through the opening 7.

The mold pig that did not fall from the mold when the mold came to the upper end 2 of the mold conveyor 1 and was turned over, dropped the mold pig on the panconveyor 4 after the mold was turned over and returned to the return run. Becomes The pig iron dropped on the pan conveyer 4 is carried to the upper end 5 of the pan conveyer 4 by the pan conveyer 4 which travels in the same direction as the mold conveyer 1, from which it falls freely into the chute 6 to receive the mold pig receiving hopper. Collected within 3.

The mold pig iron and the pig iron collected in the mold pig iron receiving hopper 3 from the mold conveyer 1 and the pan conveyer 4 are carried to a predetermined yard by transferring the mold pig iron receiving hopper 3, and the mold pig iron is received. The damper 8 of the receiving hopper 3 is opened and discharged.

As described above, by collecting the pig iron and the pig iron in the pig iron receiving hopper at the same time, the collection bag becomes unnecessary, and the pig iron collected in the collection bag is conveyed to a predetermined yard. There is no work, and there is no fear of mixing different materials.

【Example】

 An embodiment of the present invention will be described with reference to FIGS. Figure 2 is a cross-sectional view of the pig iron machine. The pan conveyor 4 is installed 1000 mm below the return mold 10 of the mold conveyor 1 from the mounting base 12 of the stationary roller 11 for assisting the return mold feed to the top of the pan conveyor 4. A chute 13 is provided to guide the pig iron on the bread conveyor.

FIG. 3 is a diagram showing the relationship between the upper end of the conveyer of the pig iron machine and the mold pigeon receiving hopper. Below the upper end 2 of the mold conveyer, the mold pig iron that freely falls from the upper end 2 of the mold conveyer is shown. A chute 6 having an opening 7 of width 3000 mm and length 4000 mm for collecting, and below the upper end 5 of the bread conveyor, is provided for collecting the free-falling pig iron from the upper end 5 of the bread conveyor. A mold pig receiving hopper 3 is provided.

The model pig iron receiving hopper 3 has wheels 14 at its lower portion and can travel on a rail 15 to a predetermined yard. Further, at the lower part of the mold pig receiving hopper 3, there is a damper 8 for discharging the mold pig and drop pig iron operated by the air cylinder 16.

As the pan conveyor, a belt conveyor can be used by lowering the pig iron temperature, and other transportation devices such as a chain conveyor and a roller conveyor can also be used. In addition, in this embodiment, in order to avoid mixing of different materials, a hopper cart (a pig iron receiving hopper) is used as a transportation means to a predetermined yard, but if there is no risk of mixing different materials, place the hopper cart on the conveyor. A chute that can be replaced and can collect the pig iron and the pig iron on the same conveyor may be provided.

As a result of operating using the pig iron machine described above, it is possible to collect the pig iron in the 100% type pig iron receiving hopper, and there is no treatment work of the pig iron, which is a good result. ing. Furthermore, there is no fear of mixing different materials.

[0017]

[Effect of the device]

 The present invention is a pig iron machine that can simultaneously collect the pig iron and the pig iron in the pig iron receiving hopper by arranging the pan conveyer under the mold conveyer. Is no longer necessary, there is no need to carry the pig iron collected in the collection bag to the specified yard, and there is no risk of mixing different materials.
