Description
Technical field
The utility model relates to a kind of oil supply system, and specifically a kind of high-quality cold-rolled steel coils is produced and prolonged machine oil supply system with rolling.
Background technology
Rolling extensions and perplexed by granular slivering so far from putting into production always, all there is granular slivering phenomenon with every group of running roller in that now rolls extensions production, and the in the situation that of just roll change, situation can be better, rolls that to prolong milimeter number more, and granular slivering is more serious.
The reason that produces granular slivering is: from rolling the impurity that contains iron filings one class inside the emulsion that prolongs oil burner nozzle ejection, and oil supply system cannot have this type of impurity is filtered completely, being sprayed on coil of strip surface at these impurity, will there is granular slivering in the coil of strip surface of producing.
If so will overcome this problem, need increase again filter plant, therefore solve the quality problems of granular slivering to set up backwash filter.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of high-quality cold-rolled steel coils production and prolongs machine oil supply system with rolling, and this system can effectively be filtered and be rolled the impurity prolonging in oil.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of high-quality cold-rolled steel coils is produced and is prolonged machine oil supply system with rolling, comprising that heating tank, pure water groove, tank diameter, first roll prolongs oil groove, filter pump, filter, second and rolls and prolong oil groove, oil pump, heat exchanger, control valve and nozzle, described first rolls and prolongs oil groove, filter pump, filter, second and roll and prolong oil groove, oil pump, heat exchanger, control valve and nozzle and be connected by pipeline successively, roll and prolong oil after nozzle is sprayed onto milling train and surface of steel plate, collect and be input to first by oil trap and roll and prolong oil groove; Described heating tank, pure water groove are connected with tank diameter by pipeline respectively, and tank diameter is rolled and prolonged oil groove and be connected by pipeline and first, and first rolls to prolong and in oil groove, be also provided with magnetic separator.
The filter arranging in the utility model is removed rolling the impurity prolonging in oil, and described filter is selected cotton paper filter.
For prevent the liquid level at cotton paper filter place too high cause rolling prolong oily filtered and just flow directly into second and roll and prolong oil groove, described cotton paper filter limit is provided with return line, when tissue paper filter pressure reduction is excessive up and down time represent that tissue paper stops up (liquid level will go up), the oil of overflow is back to first through return line and rolls and prolong oil groove.
For the ease of filter is keeped in repair, or prevent not work influence subsequent handling of filter, be connected with the first arm at described filter two ends, on described the first arm, be provided with valve.
For the ease of work such as the maintenance of heat exchanger subsequent parts, described heat exchanger output is connected with the second arm, and the other end of described the second arm exports first to and rolls and prolong oil groove, is provided with valve for controlling the use of this second arm on described the second arm.
Between described oil pump and heat exchanger, be also provided with the second filter, described the second filter is backwash filter.
The utility model can effectively be removed to roll and prolong fine particle in oil, ensures that the emulsion that prolongs oil burner nozzle ejection from rolling cleans.Significantly reduce the appearance of granular slivering, increase substantially plate face quality.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model oil supply system schematic diagram.
Detailed description of the invention
A kind of high-quality cold-rolled steel coils is produced and is prolonged machine oil supply system with rolling, and as shown in Figure 1, the oil after heating in heating tank 1 and the water in pure water groove 3 add in tank diameter 2 and stirs, and then inputs to first through tank diameter 2 and rolls and prolong in oil groove 4.Pure water in pure water groove 3 can directly inject first and roll and prolong in oil groove 4 pairs first and roll and prolong rolling in oil groove 4 and prolong oil and dilute.First rolls to prolong in oil groove 4 and is also provided with magnetic separator 15, for the iron filings of groove one class impurity is siphoned away.
First rolls the oil that prolongs in oil groove 4 extracts through filters 6 by filter pump 5, inputs second and roll and prolong in oil groove 7 after the filtration that filter 6 is cotton paper filter.Cotton paper filter limit is also provided with return line 18, and return line 18 refluxes and exports first to and roll and prolong oil groove 4.When tissue paper filter pressure reduction is excessive up and down time represent tissue paper stop up (liquid level will go up), the oil of overflow is back to first through return line 18 and rolls and prolong oil groove 4, effectively prevent the liquid level at cotton paper filter place too high cause rolling prolong oily filtered and just flow directly into second and roll and prolong in oil groove 7.
And, cotton paper filter 6 two ends pipeline the first arm 19 in parallel, on described the first arm 19, be provided with valve 17, in the time that cotton paper plugged filter cannot be exported oil, valve 17 is opened, prolong oil without rolling of filtering for the first time and directly will roll and prolong oil and export second to and roll and prolong in oil groove in 7 along the first arm 19, the rolling of input prolonged oily filtering when filtering for the second time.
Second rolls the oil prolonging in oil groove 7 is input in the second filter 9 and is carried out secondary filter by oil pump 8 extractions, can remove to greatest extent and roll all kinds of impurity that prolong in oil through twice filtration.The second filter 9 adopts backwash filter, and backwash filter has automatic cleaning function, and oil is supplied with and continued to flow during this period.
Rolling after backwash filter filters prolonged oil and entered in heat exchanger 10, and heat exchanger 10 prolongs oil and carries out temperature adjusting rolling, and prolongs oil and carries out temperature and be adjusted to suitable temperature rolling, because oil temperature is too high, oil ratio is more perishable; Oil temperature is too low, and the emulsifying effectiveness of oil can reduce, and causes insufficient lubrication.
Heat exchanger 10 rolling out prolonged oil and flowed to flow control valve 11, and control valve 11 is controlled and rolled the flow direction and the flow that prolong oil and flow to nozzle 12, makes to roll to prolong fixing running roller and the steel plate face by being rolled into direction and being ejected to milling train 13 of oil.
Heat exchanger 10 outputs are also connected with the second arm 20, and the other end of described the second arm 20 exports first to and rolls to prolong and on oil groove 4, the second arms 20, be provided with valve and open and close for the use of controlling the second arm 20.In the time that the parts in heat exchanger downstream break down or need to overhaul, or, in the time that control valve 11 is closed in order to eliminate oil pump 8 to upstream line applied pressure, can directly control valve 11 be closed (now control valve 11 or closed), rolling that heat exchanger 10 is exported prolonged oil and inputed to first along the second arm 20 and roll and prolong in oil groove 4.
Roll and prolong oil after nozzle 12 is sprayed onto milling train and surface of steel plate, collect and be input to first by oil trap 14 and roll and prolong oil groove 4, so far complete the process of complete fuel feeding, filtration and a recovery.
Above-described embodiment limits the utility model never in any form, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection domain of the present utility model.
