Description
One, technical field
The invention belongs to the magnetization filtration art, be specifically related to a kind of magnetization filter cartridge that the rolling formation process emulsion of steel plant filters that is used for.
Two, background technology
Steel plant's cold rolling mill emulsion system is the critical system of lubricated in the operation of rolling, cooling, smooth and cleaning, and it all has important role to aspects such as the rolling performance of milling train and finished strips.Emulsion of rolling mill can receive pollution to a certain degree in circulation and use, all can cause harmful effect to next procedure and strip quality.Therefore, be controlled at bottom line to the emulsion pollution and just seem very important.
In the roll operation of rolling; The band steel is immersed in the emulsion and is rolled, because the brute force between roll and the band steel plate is ground, extruding, makes to remain in the iron scale on the band surface of steel plate; And the very tiny magnetic particle (iron powder and brown iron oxide) that band surface of steel plate layer peels off formation because of rolling wearing and tearing is suspended in the 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, and this will inevitably reduce the surface quality of steel plate; And these depositions and the irony particulate that accumulates in the emulsion belong to strong ferromagnetic material; Its granularity is very trickle; Through repeatedly rolling and constantly refinement between roll and the band steel plate; It very easily with emulsion in free oil combine and form greasy dirt, progressively be accumulated as greasy filth for being difficult to filter, this can obviously reduce the service life of expensive components such as back-up roll bearing in the milling train, saddle; Because its proportion and emulsion are suitable, add that emulsion viscosity is bigger, it is very big purifying difficulty.
If iron powder in the emulsion and brown iron oxide too high levels; Will produce rolling skidding; Influence the control accuracy in the belt steel rolling process; And higher iron content also can increase the pollution level of emulsion, makes the pollution level of band surface of steel plate and roller surface increase, and influences the surface cleanness and the reflectivity of finished strip.And the iron powder in the emulsion mainly is to produce along with band steel plate rolling, 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 increasing unusually of iron content in the emulsion.Though this situation can be on production technology; Come to reduce the iron content in the emulsion through changing parameters such as concentration of emulsion used; But these parameters are all directly related with the quality of production; Can not reach the purpose of improving iron content through revising these parameters significantly, 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 made up 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 the external magnetic field; The magnetic conduction matrix is arranged in the filter cartridge; Taking over into and out of emulsion of being connected with exterior line arranged at the tank body of container two ends.Through the magnetization of external magnetic field, make through the impurity in the emulsion of container and can be filtered fuse absorption and through the backwash despumation to filter cartridge.Filter cartridge filters emulsion and has played very great function, and the variation of its structure will directly influence the effect and the backwash cleannes of deironing.The electromagnetic separation fuse of in the emulsion of rolling mill system, using at present can be divided into two types of material filling type and magnetic ball types.Material filling type electromagnetic separation machine inside is provided with the electromagnetism filler that is similar to steel wool, through electric and dead electricity and the flushing process iron powder that will be adsorbed on the steel wool is separated; Its ferromagnetism granularity be prone to emulsion in the free oil greasy filth that combines formation to be difficult to filter, 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 set inside has ball packing, through must electricly making the magnetic ball magnetize and demagnetization with dead electricity; But its magnetic is not because of there being point effect, and the magnetic force adsorption capacity is relatively poor, and the deironing rate is low.
Along with the cold rolled strip steel production development of technology; Cold-rolling process to emulsion system require increasingly high; 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 handling emulsion system.
Three, summary of the invention
The purpose of this invention is to provide a kind of emulsion magnetization filter core, with purifying and emulsifying liquid, the rolling important installations of protection iron and steel enterprise.
The technical scheme that the present invention adopts is: emulsion magnetization filter core is a cylinder-like structure; Magnetic conduction matrix and upper and lower through hole shape yoke plate that the axle that is connected by central shaft, central shaft lower end supports, is enclosed within on the central shaft constitute; Said magnetic conduction matrix is made up of the induction ring bodies and the plum blossom shape shunting collar vortex of alternate setting, and wherein the superiors and orlop magnetic conduction matrix are the induction ring bodies.
