Description

Erect-type belt steel surface oxide skin clears up production line continuously
Technical field
The present invention relates to belt steel surface oxide skin cleaning equipment, especially relate to a kind of erect-type belt steel surface oxide skin and clear up production line continuously.
Background technology
Cold-strip steel (cold-reduced sheet) take hot rolled plate as the sheet metal (thickness is generally between 0.1 ~ 2mm) of the various models that raw material is rolled at normal temperatures on request.Cold-reduced sheet of many uses, the multi industries such as aviation, train, automobile and household appliances (refrigerator, washing machine etc.), construction material, stationery, packaging for foodstuff all have application.Raw material due to cold-strip steel is hot-strip, and its surface has the hard and crisp oxide layer of one deck (the mainly oxide of iron: be outwards followed successively by FeO and Fe from inner 3o 4solid solution layer, Fe 3o 4layer, Fe 2o column crystallization layer), if the oxide layer of Surfaces of Hot Rolled Strip does not clean out, will roller surface be damaged when cold rolling production, cause belt steel surface to produce defect, affect the quality of cold rolling rear belt steel product.For ensureing that the quality of cold-strip steel finished product meets the demands, hot-strip carry out cold rolling before the oxide skin on its surface must be cleaned out.Conventional at present have chlorohydric acid pickling and dry abrasive blasting two kinds to the method for cleaning of Surfaces of Hot Rolled Strip oxide skin: 1) chlorohydric acid pickling: during pickling processes, first acid solution to be poured in descaling bath and be heated to about 75 DEG C, then band steel is kept flat by descaling bath, the oxide layer of acid solution to band steel upper and lower surface is cleared up.Because acid solution can produce acid mist pollution air in heating process, reluctant low spent acid also can be produced after acid solution uses a period of time simultaneously, and acid regeneration treatment facility somewhat expensive, general all between hundreds of to up to ten million unit, not only increase the production cost of enterprise, and treatment effect is unsatisfactory, can not the standard of meet the requirement of environmental protection.2) dry abrasive blasting descales: its principle is with mechanical centrifugal power or compressed air etc. for power, and by shot by special nozzle, high velocity jet, to belt steel surface, removes iron scale by means of impulsive force and frictional force.During cleaning, be also band steel is kept flat pass through shot-blasting machine.But the cleaning effect of this kind of method is bad, after cleaning, the cleanliness factor of belt steel surface is lower, and the dust produced when simultaneously working is large, not only contaminated environment, also seriously compromises the healthy of operating personnel.
Because above-mentioned two kinds of methods are all kept flat by band steel to clear up, the refuse not easy-clear under cleaning, also can affect the cleaning quality of belt steel surface.
Summary of the invention
The object of the present invention is to provide that a kind of operating efficiency is high, elimination effect good and the erect-type belt steel surface oxide skin of environmental protection clears up production line continuously.
For achieving the above object, the present invention can take following technical proposals:
Erect-type belt steel surface oxide skin of the present invention clears up production line continuously, comprise band steel uncoiler, bonding machine, belt steel surface cleaning plant, three roller jockey pulley planishers and band steel winder that order is arranged, between described bonding machine and belt steel surface cleaning plant, be disposed with the vertical tipper of band steel and the vertical evener of band steel; The flat tipper of band molten steel is provided with between described belt steel surface cleaning plant and three roller jockey pulley planishers; Described belt steel surface cleaning plant comprises the cleaning chamber that bottom level is provided with band steel carrying roller, the end walls center of described cleaning chamber longitudinally offers band steel entrance and band steel exports respectively along it, be fixedly installed the water sand injector mixer group that at least two row are connected with sand-feeding tube with external high pressure water inlet pipe in interval respectively along two side length direction in described cleaning chamber, in the cleaning chamber being with steel exports place, bilateral symmetry is provided with the water be connected with outside water inlet pipe and cleans shower nozzle.
For ensureing elimination effect to belt steel surface oxide skin, described water sand injector mixer group is staggered along two side setting respectively, and the opposite side corresponding with side water sand injector mixer group is provided with is with steel plate holder.
For using water wisely, the diapire sewage draining exit of described cleaning chamber is connected with dirty water collecting tank by blowoff line, described blowoff line is in series with Pulp pump and cyclone successively, the sand setting outlet of described cyclone is connected with steel sand collecting box, and the top of described steel sand collecting box is provided with drum screen; The discharge outlet of described dirty water collecting tank is connected with sedimentation basin by drainpipe, the discharge outlet of described sedimentation basin is connected with clear water tanks by water return pipeline, described water return pipeline is in series with filter pump and filter successively, the water inlet pipe of described water sand injector mixer group is connected with described clear water tanks by high-pressure pump, and the sand-feeding tube of described water sand injector mixer group is connected with described steel sand collecting box; The water inlet pipe of described water cleaning shower nozzle is connected with described clear water tanks by flushing water pump.Cleaning water used can be collected process Posterior circle like this to use, reduce water consumption.
For being suitable for the cleaning of different in width band steel, described water sand injector mixer group is made up of at least three jet blowers of longitudinal arrangement, if band steel is wider, then jet blower can be increased to six or more.
The vertical evener of described band steel comprises frame and is disposed on the front and back support roller frame in described frame, described front and back support roller frame is staggeredly equipped with successively multiple longitudinal pressure roller driven by power source.
For adapting to the band steel of different-thickness, described frame is provided with adjustment guide rail/guide groove, the bottom of described front and back support roller frame is provided with the guide groove or guide rail that match with described adjustment guide rail/guide groove, and the adjusting lever end be located in the support roller frame of described front and back is provided with adjustment handwheel.Owing to being with the thickness of steel different, the thinnest 2mm that can be, thicker can be 5mm, by the position before and after adjustment between support roller frame, can ensure the grinding pressure of longitudinal pressure roller of both sides to smooth band steel.
The invention has the advantages that compact conformation, production efficiency is high, and disposal costs are low, and Surfaces of Hot Rolled Strip oxide skin disposable removing degree is high, can substitute pickling and dry blast cleaning technique completely, meet the technological requirement of follow-up cold rolling production.Water, sand mixing during cleaning, without waste water,waste gas and industrial residue discharge, environmental protection; Be with steel vertically to place when clearing up belt steel surface, not only ensure that the thorough removing of belt steel surface oxide skin, the dirt under removing more easily is got rid of totally.
