Two, background technology
Steel plant's cold rolling mill emulsion system, be critical system lubricated, cooling, smooth and clean in the operation of rolling, and it all has extremely important effect to aspects such as the rolling performance of milling train and finished strips.Emulsion of rolling mill can be subjected to pollution to a certain extent in circulation and use procedure, all can cause harmful effect to next procedure and strip quality.Therefore, the emulsion pollution is controlled to bottom line and just seems very important.
In the roll operation of rolling, with steel, be immersed in emulsion and be rolled, due to roll and with the brute force between steel plate, grind, extruding, make the iron scale remained in on surface of steel plate, and the very tiny magnetic particle (iron powder and brown iron oxide) that peels off formation because of the rolling wearing and tearing with the surface of steel plate layer is suspended in emulsion, and these fine magnetic particles of constantly accumulating and increase, will inevitably add the wearing and tearing of big roller system, and can cause great harm to postorder production, they can stick on the band surface of steel plate, this will inevitably reduce the surface quality of steel plate, and these depositions the irony particulate that accumulates in emulsion belong to strong ferromagnetic material, its granularity is very trickle, by roll and with repeatedly rolling and constantly refinement between steel plate, it very easily the free oil in emulsion be combined and form greasy dirt, progressively be accumulated as the greasy filth for being difficult to filter, the service life of the expensive components such as the back-up roll bearing in the obvious reduction of this meeting milling train, saddle, because its proportion and emulsion are suitable, add that emulsion viscosity is larger, it is very big purifying difficulty.
If the iron powder in emulsion and brown iron oxide too high levels, will produce the rolling skidding, affect the control accuracy in the belt steel rolling process, and higher iron content also can increase the pollution level of emulsion, make the pollution level with surface of steel plate and roller surface increase, affect surface cleanness and the reflectivity of finished strip.And the iron powder in emulsion mainly produces along with the rolling with steel plate, and can because of the variation of rolling kind, emulsion stability also can variation and the situation such as sneak into of hydraulic oil or lubricating oil equally also can cause extremely increasing of iron content in emulsion.Although this situation can be on production technology, by changing the parameters such as concentration of emulsion used, reduce the iron content in emulsion, but these parameters are all directly related with the quality of production, can not reach the purpose of improving iron content by significantly revising these parameters, and its effect of these methods is also very limited.
More effective emulsion filter type is to use the electromagnetic separation machine to filter emulsion system.The electromagnetic separation machine is comprised of container, the filter cartridge that is enclosed within the external magnetic field of container outside and is contained in internal tank.Magnet exciting coil is arranged in external magnetic field; The magnetic conduction matrix is arranged in filter cartridge; Taking over into and out of emulsion of being connected with exterior line arranged at the tank body of container two ends.By the magnetization of external magnetic field to filter cartridge, make can be filtered that fuse adsorbs and by the backwash despumation through the impurity in the emulsion of container.Filter cartridge filters and has played very great effect emulsion, and the variation of its structure will directly affect effect and the backwash cleannes of deironing.The electromagnetic separation fuse of applying in the emulsion of rolling mill system at present can be divided into material filling type and magnetic ball type two classes.Material filling type electromagnetic separation machine inside is provided with the electromagnetism filler that is similar to steel wool, by electric and dead electricity and the flushing process iron powder that will be adsorbed on steel wool is separated; Its ferromagnetism granularity easily free oil in emulsion is combined the greasy filth that formation is difficult to filter, and this greasy filth and material filling type (steel wool) electromagnetism filler mixes, and very easily stops up filter cartridge.And magnetic ball type electromagnetic separation machine inside is provided with ball packing, by must electricly with dead electricity, making the magnetization of magnetic ball and demagnetization; But its magnetic is not because there is no point effect, and the magnetic-adsorption ability is poor, and the deironing rate is low.
Progress along with the cold rolled strip steel production technology, cold-rolling process is more and more higher to the requirement of emulsion system, also more and more accurate to the isoparametric control requirement of concentration, iron content, the pH value of emulsion, this just has higher requirement to the equipment of processing emulsion system.
