FLATTING MILL WITH ELONGATED WORKING ROLLS Russian patent published in 2013 - IPC B21B1/02 

FIELD: process engineering.

SUBSTANCE: invention relates to metallurgy. Thick sheet flatting mill comprises slab heating furnaces, heated slab transfer roll-table. vertical rolling stand, slab turn roll-table, roughing reversing stand with horizontal working rolls for sheet rolling and width marking-out with roll-table located there behind to feed rolled stock into furnace, finishing rolling stand and means to cut sheets into lengths. Assortment is expanded by increasing the slab length, mill efficiency and rolling stability, decreasing metal input, camber, transverse gage interference while creating of low-temperature rolling consists in making roughing stand working rolls with elongated bodies, their length L exceeding maximum width of rolled sheets. Note here that turn roll-table width and length and rolled stock feed roll-table makes $$L\cdot \sqrt{2}$$ while rolled stock feed roll-table width is not smaller than L.

EFFECT: expanded performances.
