Wangxudong: obsessed with PLC for 20 years, he turned from a migrant worker to a great craftsman

Abstract: wangxudong has been engaged in electrical automation for more than 20 years. He has presided over the preparation of more than 100 PLC programs, and presided over the completion of 47 automation equipment design, transformation and technical innovation, creating direct economic benefits of more than 30 million yuan each year

Zhengzhou, May 23, Xinhua electric roasting high-pressure impregnation system commissioning, saving commissioning costs and project construction funds of 2million yuan; Transformation of the monitoring system of the profiled pulverizer to reduce the direct economic loss of 1million yuan caused by shutdown; The pre crushing system transformation of profiled raw materials has reduced the investment in technical transformation by 1.1 million yuan

Kaifeng Carbon Co., Ltd. of China Pingmei Shenma Group has made gratifying achievements in the production of large-scale ultra-high power graphite electrodes, filling a number of gaps in this field in China. Behind its series of technological innovation and transformation, Wang Xudong is active. Wangxudong has been engaged in electrical automation for more than 20 years. He has presided over the preparation of more than 100 PLC programs, and presided over the completion of 47 automation equipment design, transformation and technical innovation. The direct economic benefits created each year reach more than 30million yuan

however, he is only a technical school graduate, and once went out to work for two years. However, since he entered Kaifeng mechanical and electrical technical school to study electrical automation, no matter how his later work changed, one thing remained unchanged in him: his obsession with PLC (programmable logic controller), especially after he joined Kaifeng Carbon Co., Ltd. in 2005

it is a kind of luck to focus on doing one thing well in life. Wang Xudong, who has been involved in the field of electrical automation for more than 20 years, is now an encyclopedia of automation equipment of Kaifeng Carbon Co., Ltd. He has mastered high and low voltage electrical knowledge, programming and application of various PLC and Siemens numerical control systems, and accumulated rich experience in maintenance, programming and transformation of Schneider touch screen, InTouch, WinCC, Monitor Pro 7.2, RSView32, Kingview6.53 and other upper computer configuration software

he can quickly master the new technology and software just promoted; He was also the first to get familiar with the new equipment that had just entered the factory. His colleagues commented that Wang Xudong had infinite potential

Kaifeng Carbon Co., Ltd. is an internationally advanced 3500t oil press system imported from American Erie press systems (Yili extrusion equipment company) when carrying out equipment automation project transformation. However, during the production and operation of the equipment, the sensor was damaged, and the arrival of imported accessories took 12 weeks, so the production of the company was facing a pause. Wang Xudong worked hard for three days and nights, and finally met the use requirements by modifying the PLC program and replacing it with the limit switch system, thus avoiding the huge economic losses of the company

since 2012, the orders of Kaifeng Carbon Co., Ltd. have been increasing, and the insufficient impregnation capacity has become the bottleneck of the company's development. Wangxudong once again boldly proposed that the process solution for the existing impregnation system is to check whether the communication line between the computer and the impact testing machine has fallen off; Check whether the online selection sensor is selected correctly; Check whether the sensor has been hit during the recent experiment or keyboard operation; Check whether the software calibration or calibration function is used before the problem occurs; Check whether the calibration value, calibration value or other information in the hardware parameters have been manually changed for optimization and transformation. After investigating and analyzing the weight of a large number of samples on the production site, especially big data, equipment and production conditions, and after a detailed interpretation of the PLC program, he adapted the original program to form a new program. Under the condition that the process conditions and parameters remain unchanged, The process alternation of the two impregnation tanks was advanced by more than 4 hours, which increased the production of more than 11000 tons of impregnated products for the company every year, increased the output value by more than 20million yuan, and saved more than 1million yuan of energy consumption every year. The high-pressure impregnation system is at the leading level in the world, safe and reliable, which makes the high-pressure impregnation system in China's carbon industry to a new level. Wangxudong said

Wang Xudong also organized experts in the 863 new materials technology field office to accept the major project in Beijing by designing and transforming the PLC program and simplifying the kneading production process, creating the first place in the same industry at home and abroad. In 2014, the company stepped up its production tasks, and it was urgent to improve the production capacity of the kneading process. In the pressure kneading process, stearic acid needs to be added, and it takes about 2 minutes to add stearic acid, accounting for 10% of the whole kneading time, which limits the capacity of the kneading process. Wangxudong made full use of the kneading time by changing the PLC program to add stearic acid synchronously when entering the slow water supply step. This change enables the company to increase the kneading capacity by 6570 tons every year, increasing the efficiency by more than 12million yuan

driven and influenced by Wang Xudong, a large number of employees joined Wang Xudong's model worker Innovation Studio. Among them, there are 6 engineers, 12 senior technicians and 19 technicians. At present, the studio has made 29 innovative achievements, 45 achievements transformation, 6 utility model patents and 1 invention patent. In 2016, the studio was rated as the model worker Innovation Studio of Henan Province (skilled talents) and Kaifeng City (skilled talents) in 2016, and wangdongxu was rated as the great craftsman of Henan petrochemical pharmaceutical system
