Description
Technical field
The utility model relates to a kind of machined and steel rolling emulsion or alkali lye and reclaims the integral type purifier.
Background technology
Must use emulsion (solution that forms after oil and the water and milkization) in machined and the belt steel rolling process, emulsion main effect in the machined and the cold rolling of strip steel operation of rolling is lubricated and cooling, emulsion can be by the iron powder and the contamination by dust that fall down in machined and the cold rolling process in recycling process, if it is unclean that these impurity that constantly accumulate clean, can impact the product quality of machined and band steel.Especially for the band steel, the polluter of these accumulations (iron powder and ash content) can enter in the stove by steel going along with together, cause the stove internal contamination, influence the decarburization effect, cause the serious dross of carbon roller simultaneously, cause the severe contamination of belt steel surface, have a strong impact on the surface quality of band steel, what influence was produced normally carries out.And the cleannes of belt steel surface are mainly undertaken by emulsion.Just must purify and recycle if improve the cleannes of belt steel surface emulsion.
Emulsion recycles in machined and steel rolling cold-rolled process.In use, above-mentioned impurity is constantly accumulation, so the emulsion that will obtain to clean, and the processing that requires emulsion also is continuous process.In machined and steel rolling cold-rolled process, the purification of emulsion generally adopts the form of other filter to carry out.And the mode that the purification of emulsion at present adopts Huffman filter or bar magnet to filter usually.For high-quality machined and the production of band steel, mainly there is following problem in the emulsion process for purifying that adopts at present:
The Huffman filter mainly is to remove iron powder and greasy dirt dust in emulsion purifies, but because the present voidage of the Huffman filter paper that adopts big (generally being 15～30 microns), iron powder and the greasy dirt dust littler than Huffman filter paper space will leak in the past, and the iron powder of this part and greasy dirt dust proportion in whole impurity very big (accounting for 75% greatly), emulsion is still very dirty.
The magnetic material filtration mainly is magnetic impurity such as removal part iron powder in emulsion purifies, and not obvious to other impurity (such as ash content) effect, the quality of emulsion still can not get ensureing; If the function that magnetic material filters is too strong, can run counter to desire again, iron powder and the emulsion that sticks on the iron powder also are filtered in the lump, and emulsion has become clear water, can't be recycling.
Also have at present inorganic ceramic membrane is used for dirty emulsion processing, but it is that dirty emulsion is carried out concentration, handles after wherein filter liquor (clear water) generally all drains into sewage plant and other sewage mixes.And the final harmless treatment that the dirty emulsion that concentrates need burn or further breakdown of emulsion just can be finished emulsion.And ceramic membrane also exists that operating pressure height, film properties restorability difference are frangible with the film pipe, the relative shortcoming such as high of price.
In addition, the band steel must carry out ungrease treatment before annealing, and purpose is to clean impurity and the greasy dirt that belt steel surface adheres to, and degreaser adopts 10% waterglass (Na
2SiO
3), 5% caustic soda (NaOH) and 85% water configuration form, concentration that must strict guarantee alkali in the use is 2.5～5.0%, temperature maintenance is at 70～80 ℃.In process of production, alkali lye recycles continuously, therefore above-mentioned impurity also will be along with the continuous increase and the accumulation of alkali lye cycle-index, impurity is accumulated to a certain degree will remain in belt steel surface in a large number in cleaning tape steel process, cause causing in band steel annealing process the decline of strip surface quality.Therefore must guarantee in process of production that alkali lye disposes cleannes preferably.At present, alkali lye reclaims the mode that adopts other filter, adopts the technology of bar magnet filtration and ceramic membrane filter more, and the bar magnet filtering technique only can be removed iron powder and be attached on the greasy dirt impurity on iron powder surface, and is not obvious to the removal of impurity oil; Though ceramic membrane filter can guarantee the cleannes of alkali lye, but there is the operation energy consumption height, alkali resistance is poor, cost is high and the defective of easily breaking, benly be: ceramic membrane is in running, be easy to react, cause concentration of lye decline in the filter process, the decline of film pipe intensity and filter liquor variation gradually with alkali.
