Description

Quick-setting sheet furnace water-cooling copper roller system with on-line monitoring and self-maintenance functions Technical Field The invention belongs to the technical field of water-cooled copper roller maintenance of a rapid hardening sheet furnace, and particularly relates to a water-cooled copper roller system of a rapid hardening sheet furnace with on-line monitoring and self-maintenance functions. Background The rapid hardening sheet technology is a key core technology for preparing the high-performance neodymium iron boron permanent magnet. The principle is that molten alloy liquid is sprayed onto the surface of a water-cooled copper roller rotating at a high speed, and ultra-high-speed cooling at the level of millions of DEG C per second is realized, so that an ideal alloy sheet with fine grains and no harmful phase is obtained. The water-cooled copper roller is the "heart" of the process. The internal processing of the device is provided with a complex circulating cooling water channel, and huge heat released by solidification is instantaneously taken away by forced water cooling, so that continuous and stable quenching effect is ensured. Uniformity and stability of the copper roller surface temperature field are preconditions for determining the uniformity of the thickness of the rapid hardening sheet, the uniformity of the structure and the absence of microscopic defects. However, the mechanical structure of the existing water-cooled copper roller has a fundamental defect which is a long-felt industry and is that the internal cooling water channel is gradually and invisible in cooling efficiency attenuation and uneven caused by corrosion and scaling. The method is characterized in that failure concealment is realized by gradually accumulating corrosion products (such as copper oxide) and scale on the inner waterway wall of the completely-sealed rotary copper roller, and the corrosion products and the scale cannot be found by conventional external observation or detection means. Failure uniformity-scaling does not occur uniformly due to waterway processing micro-differences and hydrodynamic characteristics. This results in unpredictable differentiation of the cooling efficiency of the different axial and circumferential regions of the copper roll, forming "hot spots" and "cold spots", directly causing sheet quality fluctuations. The maintenance is passive and has strong destructiveness, and only after the mass quality problem of the product occurs, the product can be diagnosed by adopting destructive modes such as shutdown, disassembly, split inspection and the like. The maintenance depends on off-line chemical acid washing, so that the period is long, the production is influenced, and the precise body and dynamic balance of the copper roller are more likely to be damaged. Therefore, there is a need for a rapid hardening sheet furnace water cooled copper roller system with on-line monitoring and self-maintenance functions to solve the problems of the prior art. Disclosure of Invention In view of the above, the invention provides a rapid hardening sheet furnace water-cooling copper roller system with on-line monitoring and self-maintenance functions, which is used for solving the problem that the prior art cannot monitor the health condition of an internal waterway in real time and self-maintain on line.
