Recently, Ma Shulong, Assistant Manager and Minister of Technology Development of Jinyu Tongda Company, was awarded the Excellent Communist Party Member of Beijing. Over the past
16 years, this scientific and technological backbone in the field of high-temperature materials has presided over and participated in more than 20 national and industrial key R & D projects, developed more than 50 kinds of new products, new technologies and new processes, and 8 achievements have been identified as international advanced or leading level, and won the honors of Beijing Excellent Young Engineer and China Building Materials Federation Advanced Individual in R & D.
Ingenuity escorts the green development
of cement industry without chromium, materials can not withstand high temperature thermal shock; with chromium, environmental protection can not be passed. In order to solve the dilemma of chromium-free technology and promote the self-control of green refractory materials, Ma Shulong led the team to reconstruct the bottom of the material system. After thousands of formula tests and iterations, the whole series of chromium-free refractory products finally moved from the laboratory to the production line. As a representative achievement, the temperature of the kiln barrel is reduced by 50 ℃ to 100 ℃ and the load of the barrel is reduced by 10% to 15% after using the low thermal conductivity mullite brick. Taking a production line with a daily output of 5000 tons as an example, after using the low thermal conductivity mullite brick, 1120 tons of standard coal are saved and 3000 tons of carbon dioxide are reduced annually. In 2021, this achievement was selected into the recommended catalogue of national industrial energy-saving technology and equipment, and now it has been running steadily on more than 50 cement kilns.
At the same time, he led the project of "Development and Industrialization of Low Carbon, Green and High Performance Refractories for Cement Industry", which achieved new breakthroughs in high temperature resistance, erosion resistance and solid waste utilization, and the overall technology reached the international advanced level. At present, the related products have covered hundreds of production lines in China and exported to Belgium, South Africa and other countries. Blast furnace long-life
refractories in
metallurgical industry are the "armor" of high-temperature industry. Whether the kiln can be stabilized and energy consumption can be reduced depends on how long this "armor" can be carried. In order to break through the technical bottleneck of blast furnace longevity and ensure the long-term stable operation of the core equipment of iron and steel smelting, Ma Shulong led the team to build the basic material system, and the data of proportioning, mixing, forming, firing and testing were not ideal. In order to get the first-hand material, he led the team to go deep into the production site, investigate the customer's process pain points, and repeatedly diagnose the "crux" of material failure from the hot kiln to the mountain of waste bricks.
Finally, a new generation of products such as plastic phase composite corundum bricks and series of castables for quick repair were successfully developed, which pushed the life of blast furnace from 5 to 6 years to more than 15 years, significantly increased the utilization coefficient of blast furnace, and reduced the frequency of maintenance and operation costs.
At present, the related products have been running steadily on the production lines of Baosteel, Shougang, Shandong Steel and other large domestic steel enterprises, and exported to Indonesia and other countries. If the follow-up service can not keep up with the
product, it is difficult for the best materials to play the maximum role in the complex production line conditions. To this end, Ma Shulong insists on getting through the "last mile" of technical services, innovatively launches the "one kiln, one file" full-cycle service model, tailor-made for each cement kiln from diagnosis, selection to construction of a systematic program-just like building an exclusive health record for each equipment, tracking the whole process and lifelong service. In order to build a solid "file", he led the team to dozens of production lines in China, squatted beside the kiln to record the working parameters, repeatedly compared the material loss rules of different raw materials and different kiln types, and fed back the accumulated field data into formula optimization and service customization. This kind of deep cultivation of "running close to customers and revolving around production lines" has upgraded the service from "standardized supply" to "personalized diagnosis and treatment". Nowadays, this model has extended from cement kiln to metallurgical blast furnace, and has become a "service card" for enterprises to develop the market. Whether the
business card is bright or not depends on whether it can withstand the test-the No.2 blast furnace project of Tata Steel, the world's largest steel giant, is such a test. Faced with almost stringent technical requirements and acceptance criteria, Ma Shulong led the team to check and verify repeatedly, from every index of material performance to every node of the construction plan, one by one deduction and excellence. The project finally passed the joint acceptance of experts at one time, and won the recognition of customers with excellent quality and service. Over the past
16 years, Ma Shulong has traveled hundreds of production lines in China, and has also gone to the countries along the "the Belt and Road". He has practiced the original intention and responsibility of a Communist Party member with refractory materials, technological breakthroughs and customized services.
