Roller box for 90m finishing mill
one.Composition of roller box
Roller box principal scenario, rear side plate, roll shaft, entrance plate, eccentric locking collar areas, EPTr sleeve, adjustable feed screw and nut.
one) ZG315-570 castings are utilized for roller box, No.forty five metal plate processed by hardening and tempering methods is utilized for rear plate and front plate. Principal circumstance, rear plate and entrance plate are processed by higher precision machining tool( this kind of as NC operating cEPTr) to make sure the substantial accuracy requirement for the spot of eccentric locking collar and roll shaft.
2) Roll shaft utilized minimal carbon alloy metal blank, soon after roughing, aXiHu (West Lake) Dis.s want to get ultrasonic flaw detection approach to quench. In orEPTto make sure the tooth surface area with substantial hardness, tooth surface need to have to get carburizing and quenching therapy right after semi-ending .Good grind of each and every round and the back again of aXiHu (West Lake) Dis.s insure its precision amp durableness with EPTr sleeve and tooth area. When the generate approach of roll shaft concluded, we need to have to get the balance check to insure the rotary precision for the duration of roll shaft’s high speed rotation(6000 Rev / min).
three) Eccentric locking collar adopt medium carbon steel casting, internal diameter and eccentric spherical are processed by CNC EPT cEPTr to make sure the eccentric length and accuracy of internal and outer diameter. Then, the adjustment precision of roll hole and the Interchangeability of each eccentric locking collar are ensured.
4)front plate, rear plate and interior elements are mainly manufactured of medium carbon metal and processed by tough chrome plating and anti-corrosion treatment method to enhance the life time.
five)To make confident the roller box can reach the assembly precision prerequisite, a 4-hour idling higher-pace trial is executed upon completion of assembly of roller box and EPTl EPT, a sleek and secure sound and no oil leakage from the joint component are necessary.
