Description
Technical field
The utility model relates to a kind of steel low power and organizes hot pickling device, is specifically related to a kind of hot pickling device adopting electromagnetic induction heating mode, belongs to metalworking technology field.
Background technology
Steel low power tissue defects is checked also referred to as macrographic examination, and it can reflect form and the characteristic distributions situation of metal macroscopic view region inner tissue and defect, is a kind of important steel product quality method of inspection. The inspection of steel low power tissue defects has hot acid corrosion test, sufur printing test, phosphorus printing inspection etc., and wherein hot acid corrosion test is most widely used. Steel low power organizes hot acid corrosion test generally to carry out in hot pickling device, carries out defect observation after steel being carried out hot acid corrosion by heating acid solution.
The method of the hot pickling device heating acid solution of prior art comprises electrically heated and steam heats two kinds of modes, all there is bigger defect. adopt steam type of heating thermo-efficiency very low, generally only can reach 30-40%, the more important thing is that steam can reduce the concentration of acid solution, affect hot acid erosion effect, and Heating temperature and heat-up time are also difficult to control, test-results tolerance range is lower, thus less employing in actual production. for overcoming this defect, Chinese invention patent " steel heat pickle test corrosion integrating device ", Shen Qing Publication day: 2013.04.24, Authorization Notice No.: CN103036501A, disclose a kind of steel heat pickle test corrosion device, it is provided with the acid solution prewarming circulating system comprising heat exchanger of graphite, two are arranged independent separately in heat exchanger of graphite inside, the pipeline of bending mutual equality again, wherein steam connected by a pipeline, acid solution connected by another pipeline, the heating to acid solution is realized by heat exchange, to solve the problem of the reduction acid strength directly leading to the method existence into steam heating. but still there is obvious defect in above-mentioned patent: one is that the mode by heat exchange heats acid solution, and this kind of noncontact type of heating obviously further reduces thermo-efficiency, and its thermo-efficiency of guestimate only can reach about 20%, and energy consumption is serious, two is that non-Contact Heating mode makes to become Heating temperature and heat-up time to be more difficult to control, it is clear that but this kind overcomes a kind of defect significantly increased the weight of the technological improvement of other two kinds of defects, and impracticable.
