Wang Yujie, head of slab continuous casting machine of Hebei Xinda Iron & Steel Group Co., LTD., joined Xinda when preparing for slab continuous casting workshop. He has rich working experience, active ideas and many methods. From the trial production of the first slab in the steel mill to the stable and smooth production line now, he and other captains joined hands to assist the leaders of the section to carry out the related work of slab production in order to complete the production and operation indicators, and was rated as the advanced producer (work) of Hebei Xinda Group in 2023.

Although Wang Yujie has rich experience in work and is the old captain of the slab continuous casting production line, he is beset with difficulties in preparing for the slab production line, which is still fresh in his memory.

When he first joined the company, he was full of confidence, for slab production has many years of experience, it can be said that it is easy to get, and he has a deep presence in the mind of the production line, and needs it at any time. However, what Wang Yujie did not expect was that before long, his confidence was replaced by a heavy sense of powerlessness, and those operations that seemed ordinary in his eyes became a problem here, which also made him gradually realize some problems. Because it is a new production line, the employees of each position on the production line have never touched the equipment, whether it is the principle of the equipment or the process operation, it is strange to them, therefore, we must solve this problem first.

He will focus on staff training, make full use of the time before and after work, organize employees to learn process knowledge, equipment principles, especially some operational details, he will also be particularly told, such as slag picking methods, due to downstream users on product quality requirements, the need for staff in the slag operation will be cleaned up. Special attention should also be paid to not integrating the slag picking rod into the molten steel, so as to ensure the quality of the product. During the preparation period, as long as he was free, he would organize the staff to practice the operation techniques, and gradually everyone became more and more familiar with the equipment and process, laying a good foundation for the test and future production.

However, although we have done a lot of preparatory work in the early stage, there will still be such problems on the scene. During the trial production, when the epidemic was raging, some employees could not come to work under the influence of the policy at that time, in order to smooth production, the staff on the job worked in two shifts, and at that time Wang Yujie was on rest, but as long as there was something on the production line, a phone call he immediately rushed to the scene to solve the problem and ensure stable production. Careful, he will also summarize the problems encountered in production, so that employees can focus on learning, learn from each other, and gradually produce more and more smoothly.

Wang Yujie is a restless person, "do a line of love, love line fine line" reflected in his body incisively and vividly. As the production line gradually stabilized, he set his sights on production cost control. In the production, he found that the use time of the intrusive nozzle is 4-5 hours, taking into account the use cost of the nozzle, Wang Yujie through repeated communication with the manufacturer, by changing the slag line, changing the operation, extending the service life of the nozzle, the service life of the nozzle can reach 8-9 hours, reducing the use cost of the nozzle.

When replacing the nozzle, it is necessary to throw waste about 1 meter, Wang Yujie is not satisfied with the waste, he repeatedly studied, through clever operation, the waste was successfully reduced to 70 centimeters, and the yield was improved.

After changing the tundage and stopping pouring, the interval of re-pouring and feeding ingot is at least 1 hour, which greatly affects the working efficiency of the casting machine, and causes a large number of head and tail billet cutting, affecting the casting rate. To this end, the steel mill has carried out the hot change research, Wang Yujie actively think of ways and measures, with the section chief to transform the intermediate charter car, adopt the method of installing the handle control system, through the handle to control the walking, the center, the lifting of the intermediate charter car, and develop the quick change process and personnel allocation of the intermediate package, and control the details. Finally successfully tackled the technology, according to estimates, each hot exchange to reduce the spring, iron filings, asbestos cloth, flat iron, and other cold material costs of about 903.62 yuan, heat exchange time saving about 60 minutes, the realization of continuous pouring, each heat exchange to create tons of steel benefit of 200 yuan, can directly create nearly 100,000 yuan/time, at least 8 times a month heat exchange, according to estimates, The annual effect can reach more than 10 million yuan.
Easier said than done. Although he has experienced multiple tests, Wang Yujie has always completed one challenging task after another with his attitude of moving forward, efficient and pragmatic spirit, pattern of holding on to his responsibilities, and actions of leading the way.

Originality writing responsibility, hard work show responsibility. Wang Yujie with the courage and practical work style to overcome difficulties, pioneering and innovative, is a typical and model for everyone to learn. If the road is blocked and long, the line will arrive. I hope that the majority of cadres and staff, draw the strength of example, forge ahead, pioneering and innovative, take the initiative, brave the burden, overcome difficulties, with a more high-powered fighting spirit and a new mental outlook, in the endeavor to achieve value, and strive to walk in the forefront of innovation and creation, for the company's high-quality development of new achievements!
