The fiery red furnace reflects the heart of the naked child

——Dong Xu, chief of the synthesis furnace process of the smelting branch of the copper company

In 2003, Dong Xu, who was born in 1981, graduated from university and was employed at the smelting branch of Jinchuan Group Copper Company. Over the past ten years, he has taken root in the front line of fire smelting, studied hard, summarized and summarized, mastered various metallurgical furnace smelting skills, innovated and created results, and "solved problems" for production, and has won the honors of advanced producer of Jinchuan Group, lean improvement star of copper company, and most beautiful Jinchuan youth.

In the years of work, Dong Xu has eliminated equipment failures countless times, which has been passed down as a good story in the factory. He refined the "five-step replacement of pneumatic chute bottom plate", "three control and two falling gates", "throat coking inhibition operation method" and other innovative projects greatly shortened the single stop maintenance time of 4-6 hours, he participated in the "reduce the heavy oil consumption of synthetic furnace" project, the annual cost savings of 1.7859 million yuan.

Electronic archives facilitate production

At the critical moment, Dong Xu was able to eliminate equipment failures in a timely and accurate manner and quickly resume production, relying on his "electronic files". In the electronic file in the computer of the control room of the synthesis furnace, the time, cause and troubleshooting solution of various equipment failures of the synthesis furnace are recorded in different categories. In Dong Xu's words, only if you have a good understanding of the health of each device on site can you handle the failure with ease. Establish a separate fault elimination electronic file for each equipment, and when encountering similar problems, searching for keywords in the computer can quickly find out the cause of the fault and the solution, provide a basis for repairing the equipment, win valuable time for the production of the branch, and also provide fresh teaching materials for the cultivation of the strength of the younger generations.

Drawing cloth bag to create benefits

In 2012, when Dong Xu was in charge of the process technology of the synthesis furnace drying system, he found that the dry bag collector filter bag consumption was large, the cost was high, and the skills of the post operator were insufficient, so he went deep into the scene for many times to carry out technical transformation of the bag collector. In order to ensure the operation effect after the transformation, the post to achieve accurate replacement, economic replacement, he will dry the bag warehouse in the 1200 cloth bags moved to the drawings, and each cloth bag positioning, marking the replacement time, detailed record of the replacement of the cloth bag vulnerable points, in the case of never waste a new cloth bag to calculate the cloth bag use cycle, so that the cloth bag consumption decreased year by year. In 2017, he proposed to replace the project with a low-pressure pulse rotary blowback dust collector, which extended the life of the filter bag from 1 year to more than 3 years after successful implementation, saving 144 hours of maintenance time and creating benefits of 5.5 million yuan.

Three "magic weapons" have been fruitful

Dong Xu's tall figure appeared on the wall behind the synthetic furnace for a while, appeared in the chute in front of the furnace for a while, and climbed the stairs to flash into the circulating water sleeve for a while... The synthetic furnace plant has ten floors, as the mayor of the district, no matter how busy he is, every day he will take three "magic weapons" - thermometer, ruler, notebook from the first floor to the tenth floor, go deep into the production site, like careful care of the child to observe and monitor the temperature of circulating water, the temperature of the furnace body, the temperature of the boiler wall; check whether there is water pipe leakage inside, outside and edge of the chute, if there is a gap, then record the depth and length of the crack, wash the depth of the pit, and strive to accurately measure a few millimeters of slight changes. Dong Xu measured the length with his footsteps, with careful observation eyes, always pay attention to the actual situation of the scene, collect the opinions of relevant technical personnel and post employees in many aspects, and strive to improve the on-site operating environment from a professional point of view, realize the lean management of equipment and facilities, reduce costs and increase efficiency. He has won more than 20 innovative achievements, 6 national utility model patents, two of which won the second prize of Jinchuan Group's technological improvement and the excellence award of technological innovation projects, 1 won the "Civilized Entrepreneurship Award and Project Award" of the 3rd World Invention and Innovation Forum, 1 won the first prize of Jinchuan Group's QC achievements, and 1 won the national QC achievement excellence award.

Two "dead reasons" lead the team

There is a black notebook on Dong Xu's desk, recording the work he wants to complete that day one by one, and every day before leaving work, he has to comb and check it, which work is completed, which one is not completed, and what is the reason for not completing? If it is a multi-party coordination problem, he will write out the solution the next day, the measures to deal with it; if it can be completed, even if it is overtime, he must ensure that the day is completed.

530,000 tons of a crane worker mistakenly grasped the wrong material, the raw material physical and chemical indicators changed, resulting in fluctuations in the batching of synthetic furnaces, as the head of the operation area Dong Xu assessed it according to the assessment system. Some people pleaded privately, saying why do you have to admit death, it is not nothing, the next example is not to get it. Dong Xu said that some emotions can be told, some emotions cannot be told, and a misoperation has led to the sweat and hard work of many people being wasted. If I leave it with affection today, it is ruthlessness at the meticulous operation of the entire process of the synthesis furnace, and even ruthlessness towards all the employees of the smelting branch.

Under the guidance of Dong Xu's "strict integration into everything", the synthetic furnace process of more than 100 people put forward nearly 600 rationalization suggestions around safe production, cost reduction and efficiency increase, and 17 people, 30 main operators and furnace directors, 6 outstanding employees became team leaders, and 7 outstanding employees became engineering and technical personnel. In 2018, the team he led won the honorary titles of "Jinchuan Group Company Worker Pioneer" and "Jinchang City Worker Pioneer".
