Description

Apparatus for injection and reverse injection of high heat slab}

The present invention relates to an apparatus for extracting high-temperature slabs, in particular, extraction and force field of a high-temperature slab in which a reverse slab generated during operation in a post-process rolling mill equipment is suitable for back-loading as cracks in a furnace. Relates to a mouth device.

In general, in the furnace operation, the slab is charged into the furnace and heated to an appropriate temperature so as to smoothly perform the rolling operation.

1 is a side view showing a working situation of a conventional high-temperature slab extraction and reverse charging device, Figure 2 is a plan view showing a working situation in FIG.

Where 1 is a furnace, 2 is a slab, 3 is a crack fork groove, 4 is a slab connection, 5 is an extractor, 6 is a fork, 7 is an inverse slab, 40 is a crack, 41 is a rolling mill and 42 is an extraction door.

Therefore, in the furnace operation in which the slab 2 is heated to an appropriate temperature in order to smoothly perform the rolling operation, the pusher-type furnace is uniformly heated in the process of charging one sheet of slab material and extracting one sheet. For the cracks 40 is installed in the heating furnace for zigzag to extract the slab (2) to the extractor (5).

When a long pause is generated in the rolling equipment due to the planned pause and post-process fault occurrence, the slab 2 that has been worked is loaded back.

In this reverse charging process, the width and length of the slab 2 are increased, and thus, the length of the reverse charging time is increased, so that the heat is generated due to the temperature deviation inside the slab. The fork groove 3 is broken and the slab 2 falls to the lower portion of the extraction door 42.

When extracting the fallen slab 2, the upper crane is guided and processed according to the line distance and lever of the wire, and the extractor 5 is repeatedly operated to reload and extract the heat of the slab 2 material. Deviations and disorders become very serious.

In the case of extracting it, the upper crane and the lever work, and the extractor 5 is repeatedly operated by the extractor to extract the slab (2) crashed due to the manpower due to the unloading of the reverse-loading slab material.

However, according to the conventional technology, the processing time is lengthened, the risk of burn disaster due to high temperature is present, the productivity is decreased due to the delay of extraction, and the quality deterioration and defect increase due to the delay of the slab back-loading time are various. Problems will arise.

Therefore, the present invention has been proposed to solve the conventional problems as described above, the object of the present invention is to reverse-loading the material extracted from the heating furnace in the reverse slab generated during the work in the post-process rolling mill as the crack of the heating furnace. By reducing the slab cleavage part in the cracked fork groove due to the long idle period of the equipment and reducing the material deviation, it is possible to prevent slab material from falling down and to quickly process the slab back-loading and extraction process safely and safely. To provide a high temperature slab extraction and reverse charging device that can be.
