Heavy duty type block mill train for wire rod,rebar making plant
1.Function of steel rolling mill(finishing mill group) The finishing mill group is composed of top crossed 45° High-speed wire-rod finishing mills. The finishing mill group is located in high-speed wire-rod workshop. Through 10 unit rack the continuous micro-tension rolling mill will be transported upstream Æ 17 ~ Æ 21mm of rolling, rolling become Æ 5.5 ~ Æ 16mm finished wire. The working speed of 90m/s is insured. The specification of end product is Æ 5.5mm.
3. Equipment performance The form of mill: Cantilever roller loop mill The quantity of frame: ten (first~third frames are Æ200 mill,fourth~tenth frames are Æ150mill) Design method: top crossed 45°, ten frames concentrated transmission.
