Xin Shiqiang: Xin Da is the same as my home! Have feelings!

Xin Shiqiang, director of Jilin Xinda Iron and Steel Co., LTD., joined Xinda in 2007 and has been associated with Xinda for 17 years. For 17 years, he shuttled in the factory and the production line, and played a song of development with passionate enthusiasm, selfless struggle and selfless dedication. In 2023, according to the needs of the work, he was transferred to the iron factory as director, under his careful management, the iron factory indicators achieved a new breakthrough in the past year, he was named Hebei Xinda Group 2023 outstanding middle-level cadres.

Xin Shiqiang attaches great importance to team building, establishes the team culture vane of "efficient execution and happy work", and "wants to be together, stand together and do together" with employees, closely unites the team in production and construction, stabilizes the staff team and has strong team execution. In a coal injection section need to urgently replace more than 500 cloth bags, in order to ensure the normal production of blast furnace coal injection, Xin Shiqiang led all the iron making section heads to collectively replace coal injection bags, only taking 4 hours to complete the bag replacement, 16 hours ahead of the usual replacement.

In terms of production, Xin Shiqiang led the team to stick to the indicators, and created the best indicator record in history for 17 consecutive days in October 2023, and made a historic breakthrough in the production index of the whole month in November.

The coal ratio index has been significantly improved, with an average coal ratio of 159 kg/ton, 11 kg/ton higher than the average index of the previous year. In October 2023, the coal ratio index broke through the best index in history. In the first quarter of 2024, the coal ratio index continued to improve, and the average coal ratio index broke through to 180 kg/ton in March, and the coal ratio index rose by 20 kg/ton of iron, achieving a major technological breakthrough.

The quality of hot metal is improved significantly, and the pass rate of hot metal in blast furnace is 100%, achieving the best record. The first grade rate of molten iron was 94.88%, 87.51%, 96.41%, which was the best index in history.

In line with the principle of process obedience, the ironmaking plant actively provides high-quality hot metal for the steelmaking plant, and carries out the research on the hit rate of furnace temperature in combination with the technical department of the company to improve the stability rate of silicon and sulfur in hot metal, while carrying out the research on silicon reduction, and gradually reducing the silicon in hot metal to below 0.3%, creating conditions for reducing fuel cost and fuel ratio, and providing high-quality hot metal for the next process.

Xin Shiqiang closely focused on market changes, focus on promoting cost reduction and efficiency work, he proposed that the ironmaking plant to "three stability as the basis", that is, safe work stability, stable furnace condition, stable equipment operation, "two potential as a starting point", that is, fuel ratio potential, fuel structure potential, "a reduction as the core", that is, the concept of hot metal cost reduction. Under his fine management, the cost of molten iron in the iron plant was the lowest in the group's steel enterprises throughout the year.

Reasonable mixing of small steel slag block, low price particle steel material and a small amount of defective block with zinc content Malay block and low quality Baishan block can effectively reduce the cost of raw material structure of hot metal.

At different stages, 10-25 and 24-40 coke particles and coke coke are added to reduce the net coke ratio in the furnace, and at the same time, each blast furnace is organized to implement large coal ratio injection research, and the coal ratio is greatly increased by about 30 kg/ton, and the index is broken, and the record is exceeded for many times.

Implement specific measures to reduce the fuel ratio, strengthen the furnace iron and screening management, carry out silicon reduction, the average silicon of hot metal is controlled below 0.3%, in order to further improve the gas utilization rate, the blast furnace adopts a large platform, large ore batch, large Angle operation policy, under the conditions of the equipment to maximize the furnace top pressure and other measures.

Safety is the basis and premise of everything, Xin Shiqiang insists on grasping the basic work of safety, improving all kinds of safety plans, safety measures, safety operation standards, and effectively carry out safety training. To strictly inspect the three violations, strengthen the team management as a means to improve the safety management. In the past year, there were no safety accidents in the ironworks.

In terms of site environment improvement, Xin Shiqiang pays attention to detail control, and accurately controls unorganized and organized projects against ultra-low emission standards. Regular operation and maintenance of the dust collector in the ironmaking plant to ensure the normal operation of the equipment and ensure ultra-low emissions.

In order to further improve the site environment, he led the team to independently carry out ground hardening and greening in the plant, covering an area of about 2,000 square meters, effectively improving the visual level of the site. In the third quarter of 2023, the iron plant lean improvement site lean, in the group A branch plant professional evaluation achieved the first place in the good results, the year-end lean normalization to maintain the acceptance of the comprehensive results for the first class plant, won the progress award.

In the face of the future, Xin Shiqiang also has a new goal, he will focus on the "stable production, excellent indicators, reduce costs, improve efficiency" work ideas, unite and lead cadres and employees to overcome difficulties, strive to advance, promote Jilin Xinda Iron and steel production and operation, transformation and development of various work to improve the quality and efficiency, so that the enterprise will be full of new vitality, show a new look, and continue to struggle for the dream of a hundred years of strong enterprises. On the road of high-quality development, every Xinda person has his or her own position, mission and responsibility. Please join hands with the majority of cadres and staff, do not forget the original intention, hard work, unremitting struggle, write more and more wonderful Xinda story!
