Xu Ying No., Hebei Rongxin Iron and Steel Co., Ltd. iron plant coal injection section, has been in the job for more than 20 years, from the maintenance worker, maintenance monitor, crane deputy section length, maintenance section length, operation section length to the coal injection section length, accumulated a wealth of practical experience, the thickness of the dozens of work notes like a computer database, small to equipment model, large to the solution, For him to accumulate a thick wealth of knowledge, repeatedly won the Hebei Xinda Group advanced production (work) honorary title.

01 Good management, promote the optimization of production indicators

Xu Ying is the coal injection section in the "backbone", all the big and small feelings are arranged by him. He can carry this burden, and he can carry it steadily. In order to ensure the stable production of blast furnaces and the improvement of the coal injection ratio, Xuying unified the idea, actively responded, organized the staff of the section to hold a special meeting, and explained the great practical significance of improving the bituminous coal ratio and coal ratio at present. All employees are required to gather strength, understand difficulties, advance, establish a sense of the overall situation, and strive to serve the blast furnace well, spray good coal, and ensure that the coal injection ratio of the blast furnace is required every month. In addition to daily equipment maintenance, Xuying stipulated the location of pulverized coal warehouse, and the pulverized coal production system must be started to ensure the supply of pulverized coal in blast furnaces.

In daily work, Xu Ying figure is always so busy and orderly. Each shift test is carried out for oxygen content linkage of pulverizing system to ensure effective and normal use; Make a special record of the phenomenon of exceeding the standard in the heat distribution furnace, and contact the heat distribution section to do the targeted fine operation of the oxygen content of the exhaust gas. Lead the staff of the section to implement the reasonable process parameters formulated by the factory, and spray evenly according to the demand of blast furnace on time and in quantity.

Only when you are familiar with the temperament of the equipment, can you have a target. Xuying strengthen the system equipment spot inspection, lubrication maintenance, standby equipment cycle switching use, do a good job at night milling equipment system peak production, electricity saving work, give full play to the equipment in the late night when the electricity is low running capacity, reasonable and comprehensive organization of milling, use downtime during the day to do mill inspection and maintenance processing. Do standard instrument vibration measurement and temperature measurement for each fan and key equipment, and deal with hidden dangers or faults in time. Not only that, Xuying organized all the central control personnel to carry out the job operation training of the work instructions, and strictly controlled the process parameters to ensure the stable operation.

02 Good innovation, focus on exploring patent achievements

Innovation is the power source of enterprise development. "We should constantly explore new technologies and processes to promote the sustainable and healthy development of enterprises." Xu Ying said firmly. About the coal pipeline end sewage collection, Xuying with professional research, to solve on-site problems as a starting point, bold innovation, the courage to break through, by installing the reverse blowing chamber on the top of the dust removal mechanism, the vent circle is fixed on the fixed cover plate through the hole, the fixed cover plate circle and the ash hopper wall seal fixed, pneumatic flange gate valve is installed at the bottom of the ash bucket. The blowback cross pipe is communicated with the vent through the blowback stand pipe, and the blowback cross pipe is connected with the blowback package and the pulse valve. The filter bag is used to filter out the pulverized coal and impurities, and the pulverized coal and impurities on the outer wall of the filter bag are blown into the ash hopper for recovery through the pulse valve and backblowing, which avoids environmental pollution, realizes recycling and reuse, and successfully obtains the utility model patent of "a coal pipeline end sewage collection device".

Not only that, Xu Ying, who has the spirit of perseverance and craftsmanship, can not stop for a moment, and insists on refining himself into an "inventor". In the study of the utility model patent "A blast furnace coal injection system to prevent air cut off air device", by connecting the air compressor outlet in the blast furnace coal injection system to prevent air cut off air device to the air tank inlet, installing an inlet valve on the pipeline between the air tank and the nitrogen tank, installing a pressure sensor on the air tank, and installing a pneumatic valve on the connecting pipe between the air tank pipeline and the nitrogen tank pipeline. When the pressure in the air tank is reduced due to the failure of the air compressor, nitrogen is input into the air tank through the connecting pipe to compensate the air pressure, prevent the sudden reduction of pressure from causing blockage of the coal pipeline, and ensure the safety of production. There is no fast track of innovation, and the slightest breakthrough in the work is fun and driving force for Xu Ying.

03 Good technical reform, crack the difficult diseases of equipment

Xu Ying, who was born in the maintenance position, gave full play to the advantages of the old bank, and investigated hidden dangers and optimized and improved the equipment of the workshop. Aiming at the problem of low function of the reducer of the coal jet impeller feeder, replace the reducer with a larger level, reduce the damage rate of the reducer, and reduce the labor of personnel repair; By replacing the aging screen of the wood chip separator and enlarging the screen hole, the coal blocking can be completely cured. In view of the problem that sometimes there is no high temperature exhaust gas in coal injection, resulting in the normal pulverization of coal injection, Xuying decided to lay pipe belts, install electronic control valves and flue gas self-circulation facilities after research, to solve the problem of coal injection pulverization due to external influence. Such technological transformation initiatives are numerous, how to make up for equipment defects, how to reduce costs, in the final analysis, Xu Ying number to the enterprise as a "home" to take care of.

The mountain is high and the road is long. Although the road ahead is difficult to climb, there are difficulties to break through, all the cadres and staff of Xinda should stand at the head of The Times, bear the heavy responsibility of development, do their best to shine wisdom in every work, ingenuity unswervingly condensing quality in every detail, clenching fists in their own posts, constantly breaking through in the professional field, paying tribute to the original heart with ingenuity, forging extraordinary with ordinary, and writing a new chapter with struggle. In the process of green and high-quality development of the group, gallop and continue to write brilliant, in the realization of the grand vision of "serving the country with industry to create a hundred years of strong enterprises", brave responsibility and tenacious struggle!
