Once ignorant youth to today's iron and blood man, shuttling in the pursuit of dreams in the years, countless days and nights, he stuck to the line, silently dedicated to the line, with 19 years of hard work and sweat to become a roll master in the industry. He is Hebei Rongxin Iron and Steel Co., LTD. Iron mill coil section day shift monitor, 2023 group advanced production (work) Liu Huanhuan.

You have to do something about it

In 2005, Liu Huanhuan came here after graduation and became a roll weighing worker, facing thick operating procedures, countless operating parameters, dazzling system diagrams... Everything in front of you, to the first steel mill Liu Huanhuan to "hit the head", is to stay? After meditation, Liu Huanhuan of resolute character made up her mind: must break!

Since then, Liu Huanhuan has set a phased learning goal for himself, doing more during the day and thinking more at night. Liu Huanhuan said: "Growth is a process, dreams need to persist." Therefore, he always adhered to the belief of serving the blast furnace production, satisfying the whole process of the blast furnace from the tank weighing to the furnace top loading. In daily work, strictly grasp the screening and weighing under the groove, screen plate cleaning, maintenance and cleaning around the weighing bucket, regular organization and calibration, to ensure that the concentrate is in the furnace, to ensure the stable operation of the equipment, and to escort the blast furnace along the line. Through years of hard work and practice, he changed from a roll worker to a qualified roll monitor. At work, he took the lead everywhere, and technically, he dared to challenge each pass of the blast furnace roll.

All the way to explore and grow

When faced with a difficult problem, most people might choose to ignore it or take a detour, but not Liu Huanhuan. In the face of problems that are difficult to solve for a while, he will devote more time to in-depth thinking and study, consult experienced senior seniors, analyze and discuss continuously combined with his own experience, and actively seek solutions to the problems. It is with this attitude that he not only mastered the blast furnace coil weighing technology, but also accumulated rich practical experience.

In September 2023, the pressure of the top tank of the furnace was less than 18kpa, and the discharge of the tank into the furnace was affected, resulting in an inaccurate number of discharge rings. Liu Huanhuan went to the scene to investigate the cause, and finally found that the lack of net gas pressure affected the discharge of materials. Therefore, he combined with the equipment department to research solutions, decided to do not affect the production of blast furnaces, in the original gas pressure balancing pipeline with pressure drilling, and run a new pipeline to the original nitrogen pressure balancing valve. After the plan was determined, Liu Huanhuan acted quickly, combined with the maintenance and opening team, carried out the transformation plan, after 2 days of efforts, the transformation was completed and the effect was good, to ensure the normal discharge of blast furnace materials.

Such innovative transformation measures are numerous, for example, the bottom plate of the flow nozzle in the middle of the east and west is often washed by materials, and the wear and tear are serious, resulting in high labor intensity of workers. Therefore, Liu Huanhuan actively studied with the same industry, looking for materials with better wear resistance, and extended the service life of the nozzle and reduced the labor intensity of workers after the nozzle transformation. The purchased coke powder surface is more, the original feeder screen body area is small, the feeder Angle is not enough, Liu Huanhuan combined with the maintenance personnel, the original small feeder is dismantled, re-make the large screen body, and the screen body Angle is enlarged, improve the screening capacity, after the transformation of the screen plate is not easy to paste the sieve, reduce the number of cleaning screen plate, put an end to the coke powder into the furnace, and ensure the furnace condition.

Persistent pursuit of this blue sky

"When it comes to environmental protection, no one should take chances." Liu Huanhuan said can also do, with excellent technology and practical and diligent attitude to eliminate all difficulties. It is proposed to transform the water pipe of the return bin, transfer the high pressure water in front of the furnace to the mouth of the bin, change the water nozzle, increase the water amount of the return bin, and eliminate the dust twice, and the effect is obvious. Because the blast furnace feeding system is A key environmental protection point, during the company's environmental performance, Liu Huanhuan took the factory as his home, led the staff to clean up the site, beautify and brighten, and did his best for the company's environmental performance to create A success. Over the years, he has always worked hard with a sincere heart and endless wisdom to make the factory more blue and the environment more fresh.

Seek in steel, sublimate in quenching. In the broad process of green high-quality development, there are many "snow mountains" and "grassland" to cross, and many "Loushan Pass" and "Lazikou" to conquer, all cadres and workers of Xinda should be in the name of struggle, with the fortitude of "thousands of grinding", "the more difficult the more forward", "not breaking the Lou LAN will not return", and the effort to overcome the difficulties to make themselves regenerate. Technological innovation gives impetus to the development of enterprises. Strive to be highly skilled talents, achieve dreams with hard work, play the most glorious colorful movement of labor, and create new brilliance on a new journey!
