Lubrication characteristics of rolling mill and Rolling Mill Machines of Two high openable housing mill with bottom screw up supplier in China
(1)Rolling Mill Machines of Two high openable housing mill with bottom screw up: its main equipment includes rolling mill working frame, universal joint shaft and its balancing device, gear frame, main coupling, reducer, motor coupling and motor, front and rear coilers, uncoiling Machine waiting.
(2)Requirements for lubrication of Rolling Mill Machines of Two high openable housing mill with bottom screw ups: dry oil lubrication, such as the input roller, pusher, discharger, vertical roller, stand, rolling mill roller, rolling mill working roller, rolling mill press Lower device, universal joint shaft and bracket, head cutting machine, looper, guide plate, output roller, turning machine, coiling machine, washing machine, spindle turning machine, shearing machine, disc cutter, edge crushing machine, chop Plate mills are used for oil lubrication; thin oil circulation lubrication, such as Baosteel 2030 five-stand cold tandem mill, for example, strip steel cooling and lubrication emulsion system and oil feeding system decoiler, five-stand machine, feeding roller, rolling Shears, guide rollers, steering rollers, coilers, gear oils, levelers and other equipment are lubricated, the 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 and gas.
(3) Commonly used medium for lubrication and cooling of Rolling Mill Machines of Two high openable housing mill with bottom screw ups: In the rolling process, in order to reduce the friction between the rolling roller and the rolled material, reduce the rolling force and power consumption, make the rolled material easy to extend, control the rolling temperature, and increase For the quality of rolled products, a process lubricating cooling medium must be added between the rolling roller and the contact surface of the rolled material.
The basic requirements for the lubrication and cooling medium of the Rolling Mill Machines of Two high openable housing mill with bottom screw up process are: proper oiliness; good cooling capacity; good oxidation stability, rust resistance and stability of physical and chemical indicators; good filtering performance; good surface properties for rolling rolls and products Washing and cleaning effect; good annealing performance for cold rolled strip steel; does not harm human health; easy to obtain oil source and low cost.
There are many varieties of lubricating and cooling media for steel rolling mills, and different rolling materials require different media; here is a brief introduction: rolling aluminum strip, aluminum foil, using kerosene with additives as the cooling lubricating medium.
WISCO 1700 cold Rolling Mill Machines of Two high openable housing mill with bottom screw up, rolling emulsion at 45-50℃ in summer and 50-55℃ in winter, the mass fraction of emulsion used is 1.2-4.5%, the highest used mass fraction is 7%, and the commonly used is above 30%. The concentration of rolled thin strip is higher, and the concentration of rolled thick strip is lower. The emulsified oil used is tested every 8 hours for PH value, mass fraction, iron soap index, and comprehensive analysis and testing once a week.
(4) Lubricating oil and grease commonly used in Rolling Mill Machines of Two high openable housing mill with bottom screw ups
Medium and small power gear reducer: LAN68, L-AN100 total loss system oil or medium load industrial gear oil;
Small rolling mill: L-AN100, L-AN150 total loss system oil or medium-duty industrial gear oil;
Gears, worm gears and sprockets for high load and harsh conditions: medium and heavy load industrial gear oil;
Rolling mill housing drive gear and pressing device, shearing machine, pusher: rolling machine oil, medium and heavy-duty industrial gear oil;
Rolling mill oil film bearing: oil film bearing oil;
Dry oil centralized lubrication system, rolling bearings: No. 1, No. 2 lithium-based grease or lithium complex grease; Heavy machinery, rolling mill: No. 3, 4, 5 lithium-based grease or lithium complex grease;
Dry oil centralized lubrication system, rolling mill: calender grease (No. 1 for winter, No. 2 for summer) or extreme pressure lithium-based grease, medium and heavy-duty industrial gear oil;
Dry oil centralized lubrication system, gear box, coupling 1700 rolling mill: compound calcium lead grease, medium and heavy duty industrial gear oil.
(5) Selection of the lubrication form of the typical parts of the Rolling Mill Machines of Two high openable housing mill with bottom screw up: the working roller and the cooling system of the rolling mill adopt thin oil circulation lubrication (including the segmented cooling lubrication system); the rolling mill working roller and supporting roller bearings are generally lubricated with dry oil. Use oil-film bearings, oil mist, and oil-air lubrication at high speeds; reducer in rolling mill gear frames, reducers, motor bearings, and electric pressure devices are lubricated with thin oil circulation; rolling mill rollers, couplings, and universal joints The shaft and its balance mechanism, and theRolling Mill Machines of Two high openable housing mill with bottom screw up window plane guide friction pair are lubricated by dry oil.
