It is distributed forecasting procedure.
Background technique
Secondary cold-rolling is further to depress strip after once cold rolling and annealing and be thinned, to improve the hardness of material
And intensity.Compared to traditional once cold rolling product, secondary cold-rolling product is with thinner, intensity is higher, processing performance is more preferable
The advantages of, it can effectively save steel material consumption, reduce environmental pollution, to well adapt to pack the hair of tank industry processed
Exhibition trend.Since secondary cold-rolling product thickness is thin, intensity is high, and it is higher to plate shape, surface quality requirements, therefore frequently with emulsification
Liquid direct-injection system carries out rolling lubrication.In secondary cold-rolling unit production process, emulsion is sprayed via the nozzle installed on spraying rack
It drenches in the strip steel at entry upper and lower surface for arriving mill roll-gap certain distance, before strip enters roll gap, emulsion is analysed on its surface
Certain thickness lubricating oil film out.By direct emission, will not recycle makes the emulsion that secondary cold-rolling unit direct-injection system ejects
It is thin suitable for thickness, intensity is high, surface quality requirements are high with, emulsion lubrication better performances, and without miscellaneous oil, impurity incorporation
Cold rolled strip steel production.
During secondary cold rolling, belt steel surface emulsification flow quantity cross direction profiles uniformity determines strip in rolling roll gap
The uniformity of width direction lubrication, directly influences the plate shape and surface quality for rolling rear strip, emulsifies flow quantity along strip width
Unevenly will lead to for direction rolls rear belt steel surface and emulsion strip mottling defect occurs.In this way, how sufficiently to combine secondary cold
Milling train group direct-injection system spraying rack and nozzle characteristic formulate the emulsification flow quantity cross direction profiles forecast of secondary cold-rolling process belt steel surface
Method is of great significance to secondary cold-rolling unit plate shape and surface quality promotion.
