Rebar Rolling Mill

The function of 135m 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 the high-speed wire-rod workshop. Through 10 unit rack the continuous micro-tension rolling mill will be transported upstream � 17 ~ � 21mm of rolling, rolling become � 5.5 ~ � 16mm finished wire. The working speed of 90ms is insured. The specification of the end product is � 5.5mm.
Structural characteristics of finishing mill
Finishing mill unit is combined with ten mills, speed increasing box, support base, arc coupling, waterproof slot, waterproof plate, the protective cover, piping and guide of finishing mill. Mill frame is composed of three 200mills and seven 150 mills, frame use top crossed 45 composition form to achieve no twisting, no contact axis, little axis and shock for equipment, besides, it decreases the center of gravity height, the stability increased as well, in the meantime, the total weight has decreased and it is easy to maintain. Ten frames are the concentrated transmission.
Roll frame is composed of roller box, bevel gearbox and spare parts of bevel gearbox.
Roller box and bevel gearbox adopt outside combinational instruction, decrease the size of bevel gearbox to decrease the weight of finishing mill, decrease the space of mills to make their structure compact. Roller box used cantilever roll loop, there is eccentric locking collar in the box to adjust roll gap. Film bearing and roll shaft are inside eccentric locking collar, taper sleeve is used to fix roll loop which is at the end of roll shaft.
Bevel gearbox is composed of the box, transmission box, spiral bevel gear roll and synchronized gears. All gears are hardened grinding gear, gear tooth correction is needed. The accuracy level of spiral bevel gearbox is six and round bevel gearbox is five to ensure the smooth working of high speed.
