Description
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:
