Rebar Rolling Mill Procedure
The production line contains continuous rolling, stepping cooling, and electric control system.
This mechanical automatic rolling line will provide high-quality products with stable capacity and low energy consumption
Billet ---Reheating furnace heating---Rolling roller---Pneumatic shearing machine (for accident)---Ø550×6(H/V) Rough rolling 1～6#(DC×6 )---1#Crank, start-stop flying shear (cut head, accident broken)---Ø420×6(H/V) Medium rolling 7～12#(DC×6)---2# crank , start-stop flying shears (cutting tails, accidental breaking)--- 1# pneumatic vertical looper---Ø320×6 (H/V) finishing rolling 13～18# (DC×6) Before, there are 6 sets of pneumatic vertical loopers of 2#～6# in the finishing rolling room.---Flying shearing, pinch roll---3# double-fold flying shears (cutting head, double ruler)---cold bed Input variable frequency roller---rack type cooling bed---aligning roller table---unloading device---cold bed output roller---500t cold shear (fixed cut)--- Shifting machine ----Inspection rack---Shifting steel inspection---Bundling---Weighing---Signage---Warehousing
After the Ø550×6 (H/V) roughing mill 6# and the Ø420×6 (H/V) rolling mill 12#, each of the start-stop flying shears are used to cut and cut the rolled parts. Accident cut (all bars and rods are used); after the Ø320×6 (H/V) finishing mill 18#, there is one start-stop type double-fold flying shear to the rolling section (for bars).
