3.3 Rebar production process：

Billets(150×150~9000mm)----re heating furnace---furnace delivery table----Pneumatic pull shears(for accident)---Ø550×6(H/V) roughing mill1～6#(DC×6)-----1 # crank, start-stop flying shear (cut head and tail, accident broken off)----Ø420 × 6 (H / V) intermediate rolling mill 7 ~ 12 # (DC × 6)-----2 # crank, start-stop flying shear (cut head and tail, accident broken off)----1# vertical pneumatic Loop----Ø320×6（H/V）finishing mill 13～18#（DC×6）(Wherein before finish rolling, finishing each provided between 2 ~ # 6 # 6 pneumatic stand Loop )----flying shear pinch roll--- 3# double length flying shear (cutting head, multiple lengths)----Cooling bed input frequency Roller conveyor-----Rack type cooling bed-----Elevating alignment roll table-----size-bridges roller-way----Unloading steel devices----Cooling bed output table----500T Cold shear(cut to length)-----Pinto moving steel machine across----Test bench---Move the steel inspection----Bundling----Weighing----Signage----Be put into storage
