Lubrication requirements for Rolling Mill for Two high openable housing mill with top screw down in China
The lubrication of equipment has many special problems, especially modern large-scale complete equipment, which has a high degree of automation, needs to withstand heavy loads with impact, high working temperature and high moving speed, and some open-air operation equipment operates under harsh environmental conditions and has a lot of dust , Wet work is prone to corrosion, which puts forward higher requirements for Rolling Mill for Two high openable housing mill with top screw down lubrication.
1. The main equipment of the rolling mill includes the working frame of the Rolling Mill for Two high openable housing mill with top screw down, the universal joint shaft and its balancing device, the gear frame, the main coupling, the reducer, the motor coupling and the motor, as well as the front and rear coilers, and uncoiling Machine waiting.
2. Lubrication requirements of Rolling Mill for Two high openable housing mill with top screw down
Dry oil lubrication
Such as the input roller table, pusher, discharger, vertical roll, stand, rolling mill roller table, rolling mill work roll, rolling mill reduction device, universal joint shaft and bracket, head cutting machine, Loopers, guide plates, output rollers, turn-up machines, coilers, washing machines, spindle turn-over machines, shears, disc shears, edge crushers, stackers, etc. are all lubricated with dry oil.
Thin oil circulation lubrication
Take Baosteel 2030 five-stand tandem cold rolling mill as an example, the decoiler, five-stand, feed roll, rolling shear, guide roll, steering roll and coiler, gear shaft of emulsion system and oil feeding system for strip cooling and lubrication Lubrication of equipment such as, leveling machine, etc.; oil film bearing system of each frame, etc.
The bearings of high-speed and high-precision rolling mills are lubricated with oil mist and oil-air.
3. Commonly used medium for lubrication and cooling of Rolling Mill for Two high openable housing mill with top screw down
In the steel rolling process, in order to reduce the friction between the roll and the rolled material, reduce the rolling force and power consumption, make the rolled material easy to extend, control the rolling temperature, and improve the quality of the rolled product, it must be in contact between the roll and the rolled material. Process lubricating cooling medium is added between the surfaces.
The basic requirements for the lubrication and cooling medium of the Rolling Mill for Two high openable housing mill with top screw down process are: ① proper oiliness; ② good cooling capacity; ③ good oxidation stability, rust resistance and physical and chemical stability; ④ good filtering performance; ⑤ on the surface of rolls and products Has good washing and cleaning effects; ⑥ Good annealing performance for cold-rolled strip steel; ⑦ Does not harm human health; ⑧ Easy to obtain oil source, low cost.
