A lifetime of love, a lifetime of progress, Zhang Youliang has shown a strong interest in machinery and extraordinary talent, often the radio at home to study, dismantle and then reassemble. In this way, the love of research interest implanted in his heart from a young age. After growing up, some common failures of household appliances such as TV sets and refrigerators, he can "easily". In 2000, Zhang Youliang entered the steel industry, ushering in a turning point in his life and starting his career in the research of automated control systems.

Now 54 years old, Zhang Youliang works as an automation technician in the electrical instrument section of the iron plant of Hebei Rongxin Iron and Steel Co., Ltd. to maintain the stable and smooth operation of the automatic control system equipment of the iron plant. With the ultimate pursuit of craftsman spirit, hard refining technology, innovation and breakthrough, it has been praised by the company's leaders and colleagues, and was rated as the advanced production (work) of Hebei Xinda Group in 2023.

Show one's skill in tackling key technological problems

For Zhang Youliang, even if he is skilled now, he will encounter various problems every time he tackles the key, just like dealing with a big exam. The hopper system of the original blast furnace ore tank in the ironmaking plant is a one-sided material preparation form, and the mixing bin is a semi-automatic batching. Due to the one-sided material preparation, there will be empty skip has stopped to receive the pit, resulting in empty skip and other materials phenomenon, if commissioned to carry out engineering transformation costs of about 300,000 yuan, after the company's leadership instructions, decided to develop their own transformation.

As an automation technician of the ironmaking plant, Zhang Youliang is duty-bound to take up the heavy responsibility and make full use of the production and maintenance gap. After spending nearly a month, the original feeding control program is dismantled and adapted, repeated calculations are made, and countless times the action of the simulated production process conditions and the corresponding relationship between the material setting sheet and the number of trains and the material type are simulated. After confirming the logical correspondence between the mine groove and the furnace top material system, the relevant control mode is determined. Hard work pays off, in his assiduous study, successfully independently prepared a new set of mine tank feeding system automatic control program. After that, the original operation screen is reconfigured, the new automatic control program is downloaded and the new operation screen is loaded. After several debugging and guiding the use logic relationship of the newly prepared feeding screen to the church staff operation, Zhang Youliang successfully put the new program and the new screen into actual production use.

Zhang Youliang proudly said that now the blast furnace tank feeding bucket system has really realized the combined feeding function of any expected system, which not only improves the production efficiency of the blast furnace, but also saves a sum of costs of outsourcing projects to achieve the purpose of stable production, energy saving and consumption reduction.

Zhang Youliang knows that technological research is a long-distance race with no end, only by trekking and continuing to forge ahead on the road of reform and innovation with practical actions, can we help the company to achieve steady and long-term development in improving quality and efficiency. Therefore, Zhang Youliang faces the challenge and constantly researches the key problems. According to the process requirements put forward by the workshops, he has completed more than 20 automatic control technical changes such as automatic cloth Angle reduction, advance opening of the stop material in three cars, remote automatic water refill function of blast furnace top expansion tank, automatic nitrogen purging during hot blast furnace change, and automatic nitrogen filling function of coal injection workshop security. Not only that, he also carried out a large number of technical changes to the requirements of other workshops, innovation and efficiency, and reached the process requirements after investment, and the user was very satisfied.

Take the lead in repairing the old

Workers say that in the hands of Zhang Youliang, the damaged equipment can be "brought back to life" and "repaired as new". The main control board in the high pressure soft cabinet was damaged during use, resulting in the corresponding equipment could not be used, after knowing this situation, Zhang Youliang purchased electronic components and repaired the main control board independently, so that the high pressure soft cabinet was put into normal use. Successively repair the damaged offline brands of Dell, Advantech, Siemens, North China Industrial control computer.

The data acquisition board of the temperature measurement station of the BF furnace body temperature measurement system was burned in batches. Due to the long order cycle and urgent use on site, Zhang Youliang took the initiative to repair the data acquisition board and purchased electronic components online at his own expense. After about a week, all the data acquisition board repair tasks were completed independently, and now all the data acquisition board cards have been put into normal use, realizing the purpose of repairing old and benefiting waste and reducing costs.

In the new era, the east wind is mighty, and the workers bravely stand at the head of the tide. Xinda all cadres and staff should consciously shoulder the heavy responsibility of The Times, unify the thought and action to the deployment requirements of the group, integrate the life ideal and career pursuit into the new task and new journey of the development of the group, so that the responsibility is in the heart, the responsibility is in the body, the responsibility is in the line, the love and dedication, the effort is promising, and the powerful force of deepening the quality and efficiency is gathered. Strive to be the practitioner of high-quality transformation, the promoter of lean operation, the promoter of comprehensive deepening of reform, the promoter of enterprise harmony and stability, and further promote the formation of full innovation and creation, fine management of the whole process, all-round reform and efficiency, and the vivid situation of mutual assistance and unity of the whole group!
