The advantage of vertical miller slab hot-rolling lubricating:
Define oil film at roller surface after using ROLLING OIL, reduce coefficient of friction so that the working condition of edger roll has had very
Big improvement, uses edge rolling to lubricate and can obtain following benefit:
(1) surface appearance of edger roll is improved
After having sprayed ROLLING OIL to edger roll and defined oil film, on the one hand reduce coefficient of friction also inhibits oxide layer simultaneously
Formation speed, the carbon on the other hand cracking out due to oil molecule and oxygen fast reaction, reduce the oxygen concentration in environment, make
Roller surface generates Fe3O4, Fe3O4(and is commonly called as black ferrum and sees figure) there is the hard and feature of densification, under the effect of ROLLING OIL
The roll surface of these " black ferrum " can be changed into the surface with metallic luster, has good wear resistence, thus substantially increases
The stability on edger roll surface, effectively extends the service life of roll.
(2) reduce edger roll consumption, extend the activity duration of one group of roll
Reduce the force-bearing situation on edger roll surface after using hot-rolling oil, thus decrease roll wear and stock removal, simultaneously roll
Life decreases roll change number of times and extends the rolling operation time of roll.
(3) power consumption is reduced
Owing to significantly reducing coefficient of friction after use ROLLING OIL, thus roll-force can be reduced and saves energy.
(4) product surface quality is improved
Owing to edger roll surface is under lubricating status, there is the surface of metallic luster, thus base type and size be just easier to control,
The limit of strip steel is split significantly change.Good profile and surface condition is provided for follow-up finish rolling.
The lubricating system of the present invention includes fuel feeding part, water supply part, mixing control part, spray header device, source of the gas
Supply and recharging oil device, edger roll hot-rolling lubricating is to a kind of special lubricant (rolling of edger roll surface spray-coating in the operation of rolling
Oil and the mechanical impurity of water), by the rotation of edger roll, bring lubricant into contact in rolling, make edger roll and rolled piece surface shape
Become 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 using oil and water to be mixed into mechanical mixture liquid by a certain percentage plays profit through nozzle spray feed equably on edger roll roll surface
Sliding effect.Oil supply system and water system is the most intensified, filter, measure and through control valve platform containing blender, after mixing
Profit mechanical mixture liquid, deliver to edger roll roll surface by injection line and be lubricated.
