Description
Technical field
The utility model belongs to rolling lubrication technical field, is specifically related to a kind of mill roll-gap lubricating arrangement, the especially a kind of dual purpose roll gap lubrication device that can simultaneously realize working roll roll gap lubrication and backing roll roll gap lubrication.
Background technology
Along with the development of steel rolling technology and the more fierceness of market competition, steel market is day by day harsh to the requirement of thin strip quality, and hot rolling mill to continuously, at a high speed, large-scale, increasingly automated future development, the life cycle of roll has a great impact rolling mill yield, because roll gap lubrication has the roll-force of reduction, roller consumption, power consumption and improves the functions such as strip surface quality, many steel mills have increased roll gap lubrication system.
What roll gap lubrication system applies was more at present is mainly divided into working roll roll gap lubrication and two kinds of modes of backing roll roll gap lubrication, relatively these two kinds of modes, the ROLLING OIL consumption of working roll roll gap lubrication is relatively less, but need to stop working roll entrance cooling water, thereby has affected working roll cooling effectiveness; And backing roll roll gap lubrication is larger in roll-force, roller consumption, the power consumption range of decrease, does not need the cooling water of working roll of stopping using, but need good water effect and the more ROLLING OIL of cutting, but apply less.In order to give full play to the advantage of these two kinds of modes, the way adopting is at present that two cover systems are installed respectively in single chassis, like this, has caused equipment component many, system control complexity, and probability of malfunction is high, and cost has high input.
Summary of the invention
For the problem existing in background technology, the purpose of this utility model is to provide a kind of dual purpose roll gap lubrication device that can realize working roll roll gap lubrication and the conversion of backing roll roll gap lubrication.
For achieving the above object, the dual purpose roll gap lubrication device of the utility model design, its special character is: comprise supply circuit and lower supply circuit; Described upper supply circuit includes with lower supply circuit the oil pump, flow sensor, check valve, the blender that are connected successively; The oil-in of described oil pump connects the first ball valve, and the import of described the first ball valve is connected with working roll rolling fuel tank and backing roll rolling fuel tank; Described blender connects working roll pipe collection and backing roll pipe collection by the second ball valve; Described blender import also connects stop valve, flowmeter, control valve and water inlet pipe successively.
Further, described the first ball valve is tee ball valve; The sprue of above-mentioned tee ball valve is connected with described oil pump import, and two runners are connected with working roll rolling fuel tank and backing roll rolling fuel tank respectively.
Further, described the second ball valve is tee ball valve; The sprue of above-mentioned tee ball valve is connected with described mixer outlet, and two runners are connected with working roll pipe collection and backing roll pipe collection respectively.
Further, between described the first ball valve outlet and the outlet of described oil pump, be provided with overflow valve.
Further, the pipeline that described stop valve is connected with blender is provided with quick union.
The beneficial effects of the utility model are can be according to manufacturing technique requirent, between working roll roll gap lubrication system and backing roll roll gap lubrication system, quick switching used, and because this device has independent circuit controls up-down rollers, can realize the adjusting control of up-down rollers flow and concentration, to reach best result of use; This device is simple simultaneously, compact, cost is low, convenient operating maintenance.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model dual purpose roll gap lubrication device;
In figure: oil pump 1, flow sensor 2, check valve 3, blender 4, the first ball valve 5, working roll rolling fuel tank 6, backing roll rolling fuel tank 7, stop valve 8, flowmeter 9, control valve 10, water inlet pipe 11, working roll pipe collection 12, backing roll pipe collection 13, the second ball valve 14, overflow valve 15, quick union 16, water filter 17.
Detailed description of the invention
As shown in Figure 1, the dual purpose roll gap lubrication device of the utility model design, comprises supply circuit and lower supply circuit; Described upper supply circuit is consistent with lower supply circuit structure, and upper and lower supply circuit has a point at the first ball valve 5 places.
Choose supply circuit below the utility model is further launched to explanation: as shown in Figure 1, upper supply circuit includes the oil pump 1, flow sensor 2, check valve 3, the blender 4 that connect successively; It is tee ball valve that the oil-in of described oil pump 1 connects the first ball valve 5, the first ball valves 5; The sprue of above-mentioned tee ball valve is connected with described oil pump 1 import, and two runners are connected with working roll rolling fuel tank 6 and backing roll rolling fuel tank 7 respectively; Form so upper roll gap lubricant passage way;
Again as shown in Figure 1, described blender 4 imports also connect stop valve 8, flowmeter 9, control valve 10 and water inlet pipe 11 successively; Like this, formed upper roll gap lubrication water route;
Again as shown in Figure 1, described blender 4 exports by the second ball valve 14 and connects working roll pipe collection 12 and backing roll pipe collection 13, described the second ball valve 14 is tee ball valve, the sprue of above-mentioned tee ball valve is connected with described blender 4 outlets, and two runners are connected with working roll pipe collection 12 and backing roll pipe collection 13 respectively.
