Layout of slab storerooms and furnaces for separate charging of cold blanks and hot blanks of thick plate, and furnace charging method

A slab library for separate storage of cold blanks and hot blanks of heavy plates and heating furnace layout, comprising:

• 1 # slab library span for storing the blanks which need to be stored for a long time, or cold blanks;
• 2 # slab library span, i.e. feeding span, arranged side by side on one side of the 1 # slab library span, for stacking hot blanks which need to be temporarily stacked for a short time (i.e. hot blanks to be fed), or for storing cold blanks to be fed, wherein a continuous casting blank delivery roller way connected to a continuous casting process is arranged at an inlet of the 2 # slab library span;
• and, a cold blank zone and a hot blank zone are respectively arranged within the 1 # slab library span and the 2 # slab library span;
• heating a furnace span arranged at an outlet of the 2 # slab library span, wherein more than two heating furnaces are arranged in the heating furnace span, and arranged side by side at the outlet of the 2 # slab library span, wherein the heating furnaces are corresponding to the hot blank zone and the cold blank zone;
• slab preparatory library span, which is across the inlets of the 1 # slab library span and the 2 # slab library span, i.e. a hot blank zone, wherein the continuous casting blank delivery roller way passes through the slab preparatory library span;
• span-crossing traverse trolley roller way, which is across the cold blank zones of the 1 # slab library span and the 2 # slab library span, and the heating furnace span;
• span-crossing roller way, which is across the slab preparatory library span and the 1 # slab library span, for delivering the blanks from the slab preparatory library span or the blanks from the continuous casting blank delivery roller way to the 1 # slab library span;
• and
• feeding roller way, arranged between the 2 # slab library span and the heating furnace span, and across the hot blank zone and the cold blank zone of the 2 # slab library span and the two ends of the heating furnace span, wherein the feeding roller way has a structure for delivery in two directions.
