Description
Technical field
The invention belongs to the rolling field of hot-strip, specifically be applicable to lubricating device for hot rolled steel strip rolling technology.
Background technology
Since 2000, domestic hot-rolled strip production line constantly increases, and rolling strip requires also more and more wideer, and intensity is more and more higher, and market competition is also more and more fierce, also requires more and more higher to product quality, thin specification rate, production cost.In order to improve the quality of products, reduce production costs, improve thin specification productivity ratio, the lubrication in heat-rolling process device constantly is designed to use, but really the lubrication in heat-rolling process device can be used to such an extent that extraordinary producer is extremely rare at home.Its main cause is as follows:
1, the lubrication in heat-rolling process device cost that comes into operation is higher.Because the lubrication in heat-rolling process device needs to use separately the water supply pumping plant, and must use industrial fresh water, cause the cost that comes into operation higher.
2, the technological lubrication equipment dependability is poor in the rolling-mill housing.Technological lubrication device structure complexity in the rolling-mill housing, ferrule-type compression joint is extremely many, and all adopt and be rigidly connected, magnetic valve is the designs fix frame not, and vibratory impulse is very big when mill milling or roll change, very easily cause problems such as pipe joint is loosening, pipe cracking, fracture, magnetic valve disengagement, cause leak, leakage of oil, cause working roll to skid and cause other accident such as heap steel.
3, the installation of technological lubrication equipment, the non-constant of maintainability in the rolling-mill housing.Because technological lubrication equipment all adopts and is rigidly connected in the rolling-mill housing, and the spray thrower water inlet pipe need carry out bending to a certain degree, and spare part interchangeability extreme difference, causes very difficulty of installation.
4, profit mixes the back from being sprayed onto working roll apart from too far away, causes water-oil separating, and lubricant effect is poor.
Summary of the invention
The objective of the invention is to overcome the problem that the rolling lubricating arrangement exists, a kind of lubricating device for hot rolled steel strip rolling technology is provided.
For achieving the above object, the technical solution used in the present invention is: the outlet of fuel tank links to each other with the oil feed pump inlet, the fuel feeding delivery side of pump connects the inlet of the first fuel feeding measuring pump and the second oil feed pump measuring pump respectively, first fuel feeding metering delivery side of pump connects the inlet of the first lubricating oil solenoid electric valve through pipeline, and second fuel feeding metering delivery side of pump connects the inlet of the second lubricating oil solenoid electric valve through pipeline.Turbid circulating water is gone into the inlet of filter through main line, the outlet of filter connects the inlet of pressure-reducing valve, the outlet of pressure-reducing valve divides two water supply to divide pipelines: first supplies water divides pipeline to connect the port of export connection of first water yield adjusting control valve with the first lubricating oil solenoid electric valve after first switch is gone into first water filter, connectivity points is of first oil-water mixer in succession, one of the other end of first oil-water mixer and first metal hose links to each other, the other end of first metal hose is connected into first spray thrower, and the shower nozzle of first spray thrower is facing to top working roll; Divide pipeline after second switch is gone into second water filter, to connect of the port of export connection of second water yield adjusting control valve from second water supply of pressure-reducing valve outlet with the second lubricating oil solenoid electric valve, connectivity points is of second oil-water mixer in succession, one of the other end of second oil-water mixer and second metal hose links to each other, the other end of second metal hose is connected into the second shower pipe, and the shower nozzle of second spray thrower is facing to bottom working roll.It between top working roll and bottom working roll rolled piece (as hot-strip).At first spray thrower and other cooling water collector and the following cooling water collector of being equipped with of second spray thrower, first water discharging board and the second water discharging board position are on the next door of last cooling water collector and following cooling water collector.
Adopt a kind of lubricating device for hot rolled steel strip rolling technology that as above technical scheme provides compared with prior art, technological merit is:
1. water supply installation does not need independent water supply pumping plant, can directly connect turbid circulating water, does not need to replenish separately industrial fresh water, has greatly reduced investment and production operating cost.
2. technological lubrication equipment dependability height in the rolling-mill housing.To be divided into three sections be water supply part, fuel feeding part, spray thrower part to technological lubrication equipment in the rolling-mill housing, and device structure is simple, and pipe joint is few and all adopt socket-welding fitting; Adopt metal hose to be connected between spray thrower and the oil-water mixer, increased the antivibration ability of technological lubrication equipment; The magnetic valve design has fixed mount, can prevent that magnetic valve is because of problems such as rolling mill vibration cause that magnetic valve gets loose.
3. technological lubrication equipment is installed in the rolling-mill housing, maintainability is very good.Owing to adopt metal hose to be connected between technological lubrication device spray collector and the oil-water mixer in the rolling-mill housing, and all stainless steel socket-welding fittings all scribble happy safe anti-interlock glue when installing, install, dismounting is very convenient, technological lubrication equipment water supply part, fuel feeding part, any part of spray thrower part all can be carried out integral replacing with it in the rolling-mill housing within 10 minutes.
4. profit mix the back to ejection from the working roll distance less than 1m, profit segregation phenomenon, high lubricating effect can not occur.
