Release time:

2022-04-12

Since entering the factory for internship in 2009 , Liu Haihua has been in Daye Peak for 13 years and has changed his status several times. He has served as a central control operator, on-site monitor and production supervisor. In 2019 , he has also served as a cement mill process supervisor in "to " . Cement grinding is the last process of production. Since then, the information of unsatisfactory output, urgent inventory and high loss of product temperature has become the problems he often faces at work scheduling meetings, which often makes him nervous and determined to change.

Although Liu Haihua graduated from the major of inorganic non-metallic materials, he had to start everything from scratch after he switched to the cement mill process. It is conceivable that he did not adapt. In order to enter the normal working state as soon as possible, he and the cement mill operator groped for the change rules of the output, specific surface area and cement temperature at the mill every day, and modestly asked the craftsman how to adjust the grading of steel balls in the mill. In order to get the first-hand original data, he drilled into the mill for material sampling, checked the main grate plate of the ball position, and went down to the V selection and steady flow bin to check whether the scattering plate and buffer platform, sampling at irregular intervals in the material return pipe to see if the powder selection efficiency is reasonable ... During that time, Liu Haihua spent the longest time in the cement mill, and he was also the dirtiest in his work clothes. Through half a year's efforts, the economic indicators of the cement grinding system have reached or exceeded the best level in history. However, Liu Haihua knew in his heart that this was never enough and was still far from meeting the market requirements. In

2020 , Liu Haihua took advantage of the opportunity to attend the cement technology exchange meeting in Nanchang and Shandong, consulted a number of top grinding experts in the industry, referred to the successful cases of excellent grinding enterprises, and combined with the actual situation of the company, put forward the technical renovation plan of changing two warehouses to three warehouses for cement grinding, optimizing the V selection blanking pipe, and took advantage of the Spring Festival overhaul opportunity to implement. After the transformation was completed and put into operation, the average hourly output of the two cement mills increased by 20 tons, and the cement temperature of the mill was effectively controlled, and the cement performance was also significantly improved.

In the two years since the new coronary pneumonia epidemic continued to affect, the technical transformation of Daye Peak has not been relaxed, and Liu Haihua has not been free. In 2020 , in addition to the technological transformation of production improvement, the cement mill process also carried out the technological transformation of lithium slag use, which not only eased the procurement pressure, reduced the cost of raw materials, and improved the grindability of cement. 2021 , the technical transformation of slag hopper was completed, and wet slag was used instead of high-priced fly ash to relieve the procurement pressure while ensuring sufficient supply of active mixed materials for cement mills, it also created conditions for the later exploration of new low-cost replacement of raw materials ... Through this series of transformation measures, the economic and technical indicators of the cement mill, such as the hourly output and energy consumption, have been continuously optimized, laying the foundation for the full release of Daye's peak production capacity and the further expansion of the market. Daye Peak 2021 sales increased significantly, cement mill series of technical changes played an important role.

At the same time, 2021 Daye Peak Cement Mill Process also carried out post merger, the original mill post and feeding post combined into one, to achieve the purpose of reducing staff and increasing efficiency.

2022 Liu Haihua is still very busy. In the recent Spring Festival overhaul of 2022 , he proposed to replace the cement grinding lining plate with a new type of 5 wave ultra-thin lining plate 3 circulating fan. At present, energy saving and efficiency improvement have been implemented. After picking up the beam in the cement mill for several years, he also mastered a lot of "magic weapon " : using the experimental data of the small mill to adjust the grading of steel balls, using the data of the particle size analyzer to adjust the working conditions of the mill, and minimizing process accidents through curing process parameters and regular process inspection, etc. Of course, there is no end to progress. Liu Haihua has also set himself the next "small target " , that is, the power consumption of tons of cement grinding reaches the level of GB16780-2021 . Therefore, the technical transformation of 4# roller press to improve production and reduce consumption has been listed in his schedule.

In the eyes of colleagues, Liu Haihua is not talkative and even a little dull, but he must do well what he looks. In Daye Peak for more than ten years, he has grown up step by step with the development of the enterprise. He said, "Company has given me a platform for growth, and I will also contribute to the development of the company through my own efforts " . (Wang Yiyan)

Peak's "Centennial" Ideal

Editor's note: During the National Day, the "Jinhua New Observation" column of Jinhua TV Station launched a series of reports on "National Day New Observation: New Development of Old Enterprises" to understand the new developments of those old enterprises that have grown up with New China in the new era. October 3 broadcast of the "peak of the 'centennial 'ideal", about the development of the peak group and the future direction of development. The "century" ideal of the peak Jinhua TV reporter Wang Dujuan Jiang Qian host: speaking of Zhejiang Jianfeng Group Co., Ltd., Jinhua people are no stranger. The older generation of Jinhua people are more familiar with, may be the predecessor of Jianfeng Group-Jinhua Cement Factory. Open the first old photo 58 years ago, surrounded by mountains and a rice field in the middle. Old Jinhua can see at a glance that this is the Wise Temple, 8 kilometers north of Jinhua City and east of the former Zhuangtou of Luodian Town. In August 1958, the first group of pioneers came here and built Jinhua's first cement factory on a desolate hillside of 16.94 mu with a pair of hands and warm blood. From the earliest cattle-drawn ball forming machine to the electric ball forming machine, from pure manual labor to machine substitution, it took 26 years of hard work. By 1983, the annual output of peak cement reached 120000 tons, the output value was 6.75 million yuan, and the profit was 2.4 million yuan. In these 26 years, the cement plant has experienced a difficult period of the country, and the ten-year catastrophe of the "Cultural Revolution" has finally ushered in a good time of reform and opening up with tenacious vitality, laying the foundation for steady development in the future. Looking at these old pictures,

The total investment of the project is 1.533 billion yuan. Upon completion, it can be used for Boeing 737 series, Airbus A319 and A320 series, MA-60 and other passenger aircraft take off and land. Since the start of the Lancang Airport project, Yunnan Peak has listed it as an important goal to strive. Compared with ordinary cement, special cement for airport runways has the characteristics of small shrinkage, strong wear resistance, good frost resistance and low alkali content in addition to the requirements of ordinary 42.5 Portland cement. To this end, Yunnan peak in the project to strive for at the same time, the collection of technical forces to tackle the problem, in the clinker composition to determine, cooked.
