Wang Xudong: obsessed with PLC for 20 years, he turned from a migrant worker to a big craftsman

Abstract: Wang Xudong 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 technological innovation, creating direct economic benefits of more than 30 million yuan per year

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

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. Wang Xudong 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 technological innovation, creating direct economic benefits of more than 30 million yuan every year

but he is only a technical school graduate, and he once went out to work for two years. However, since he entered Kaifeng electromechanical technical school to study electrical automation, no matter how his later work changed, one thing has never changed 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 the high and low voltage electrical knowledge, the programming and application of various PLC and Siemens numerical control systems, and has accumulated rich experience in the maintenance, programming and transformation of upper computer configuration software such as Monitor Pro 7.2, RSView32, Kingview6.53 and so on

he can quickly master the new technology and software just promoted; He was also the first to be familiar with the new equipment that entered the factory soon. 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, and the production of the company was facing a pause. Wang Xudong worked hard for three days and nights. Finally, he modified the PLC program and replaced it with the limit switch system to meet the use requirements, avoiding 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. Wang Xudong once again boldly proposed that the process solution of the existing impregnation system is to check whether the communication line between the computer and the impact tester is falling 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 calibration or calibration function of the software is used before the problem occurs; Check whether the calibration value, calibration value or other information in the hardware parameters have been manually changed, and optimize the process. After investigating and analyzing the weight of a large number of samples on the production site, especially big data, equipment and production conditions, unless you test the machine, after a detailed interpretation of the PLC program, he adapted the original program to form a new program. Under the condition of ensuring 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 20 million yuan, and saved more than 1 million 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. Wang Xudong 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 production task of the company was stepped up, 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. Wang Xudong 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, with an efficiency increase of 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 achieved 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 Wang Dongxu was rated as the great craftsman of Henan petrochemical pharmaceutical system
