The advantages of vertical miller slab hot-rolling lubricating:
Oil film is formd in roller surface using after ROLLING OIL, reduces friction coefficient so that the working condition of edger roll has
Very big improvement can obtain following benefit using edge rolling lubrication：
(1) improve the surface appearance of edger roll
After having sprayed ROLLING OIL to edger roll and having formd oil film, on the one hand reduce friction coefficient and also inhibit oxygen simultaneously
Change the formation speed of layer, on the other hand due to the carbon that oil molecule cracks out and oxygen fast reaction, the oxygen reduced in environment is dense
Degree so that roller surface generates Fe3O4, Fe3O4（It is commonly called as black iron and sees figure）Have the characteristics that it is hard and fine and close, in the work of ROLLING OIL
The surface with metallic luster can be changed into the roll surface of lower these " black iron ", there is good wear resistence, so as to greatly increase
Add the stability on edger roll surface, effectively extend the service life of roll.
(2) edger roll consumption is reduced, extends the activity duration of one group of roll
Using the force-bearing situation that edger roll surface is reduced after hot-rolling oil, so as to reduce roll wear and stock removal, simultaneously
Roll campaign extension decreases the rolling operation time that roll change number extends roll.
(3) power consumption is reduced
Using, due to significantly reducing friction coefficient, electric energy being saved so as to reduce roll-force after ROLLING OIL.
(4) product surface quality is improved
Since edger roll surface is under lubricating status, there is the surface of metallic luster, thus base type and size are just easier
Control, the side of strip, which is split, apparent change.Good shape and surface condition are provided for subsequent finish rolling.
The lubricating system of the present invention includes fuel feeding part, water supply part, mixing control section, spray header device, air source
Gas supply and recharging oil device, edger roll hot-rolling lubricating are to a kind of special lubricant of edger roll surface spray-coating in the operation of rolling（Rolling
The mechanical impurity of oil and water）, by the rotation of edger roll, bring lubricant into contact in rolling, make edger roll and rolled piece surface shape
Into one layer of oil film.This layer of oil film improves the deformation condition of deformed area, alleviates edger roll abrasion, improves product surface quality.
The form of mechanical mixture liquid is mixed in a certain ratio into through playing profit on nozzle equably spray feed to edger roll roll surface using oil and water
Sliding effect.Oil supply system and water system are respectively through being pressurized, filtering, measuring and through the control valve platform containing mixer, after mixing
