Description
Technical field
A kind of high-precision cold rolling plant is the utility model is related to, more particularly to a kind of very thin cold rolling band steel equipment.
Background technology
Existing cold-rolling equipment is by main mill and uncoiler, straight peen straightener, coiling machine, transfer, hydraulic shear, thickness measuring
The ancillary equipments such as instrument, degreasing unit, tension force press-roller device, centralising device, feeding roller and couple these equipment guide plate, profit
The auxiliary devices such as cunning, hydraulic pressure, oil removing and its electric control system are formed, and wherein main mill is a stand four-high rolling mill or six rollings
Machine.There are elastic flattening the sheet metal thickness of rolling is had a minimum value for roll, thinning with the sheet metal thickness of rolling, rolling pressure
Power increase, the flattening amount of roll are consequently increased.When thickness of slab is thin arrives certain certain value, since the flattening of roll makes the operation of rolling not
It may carry out, thickness of slab at this time is known as minimum rolled thickness.Under same units pressure, the elastic flattening and roller diameter of roll
It is directly proportional.In order to obtain thinner plate, it should reduce the flattening amount of roll.When the timing of roll material one, to reduce roll
Elastic flattening value, must just reduce roller diameter；And the reduction of roll diameter of roller, it is corresponding to occur that roll insufficient rigidity causes cold rolling smart again
The problem of degree reduces.
