Description

[Detailed Description of the Invention] The present invention relates to an apparatus for processing short thick steel plates produced from thick steel plates after hot rolling.

Generally, when a custom-made product of a predetermined size is cut from a thick steel plate after hot rolling using a shearing machine or the like, an extra length portion is generated at both ends or one side of the thick steel plate.

Some of this extra length is scrapped, and some is not scrapped and sold as intermediate products.
The intermediate product taken from the extra length of the latter is called a short thick steel plate.

Conventionally, such short thick steel plates (hereinafter referred to as short steel plates)
is a custom-made thick steel plate of fixed length (hereinafter referred to as fixed-length steel plate), which is removed from the steel plate conveyance line that is set up to convey it to the next process, and is processed after being conveyed to another short steel plate conveyance line. It is customary to
