  • Detail

On September 10, after three days of efforts, the technology of MCC Baosteel successfully transformed the proportional valve of Baosteel Special steel strip plant Batch test: the sixteen proportional valves of the continuous rolling production line of the special steel strip plant were successfully reconstructed for the samples with the same parameters. For the maintenance task of the continuous rolling production line of Baosteel Special Steel Strip Plant, during the daily maintenance process, 16 finishing mills often fail to move horizontally, forcing the whole rolling line to shut down for troubleshooting

On September 10, after three days' efforts, the 16 proportional valves of the continuous rolling production line of Baosteel Special Steel Bar Plant were successfully reconstructed by the technology of Baosteel, MCC

for the maintenance task of the continuous rolling production line of Baosteel Special Steel Strip Plant, the polyurethane plate itself can play a very good role in heat preservation during the daily maintenance process. Often, 16 finishing mills from the global automotive industry and related fields are forced to shut down the whole rolling line for troubleshooting. Every time, the electrical, hydraulic and other systems need to be comprehensively inspected, which takes a lot of time. In order to effectively improve the maintenance efficiency, the fifth branch has gradually explored the transformation method after long-term maintenance practice. In addition, the owner will be transformed at the first time. After checking the site for many times with the owner and consulting the drawings, it is finally decided to transform the hydraulic proportional valve system. The electrical maintenance personnel rearranged the wiring in the proportional valve stand by changing the module in the computer control program, and added the valve switch button in the external design. If necessary, the manual reversing valve can be manually poked to realize the lateral operation. The manual reversing valve is durable without frequent replacement

the sixteen proportional valves, all of which were tested, were successfully transformed into a valve hydraulic testing machine. In many simulated operations, all parameters met the design requirements and could be operated normally. After the transformation, the valve can be manually opened for maintenance during production, so that the rack can continue to operate, greatly reducing the troubleshooting time, thus promoting the maintenance efficiency
