The development direction of China's refractory industry
From 2011-2020, China's refractory industry has entered the fast lane of development and achieved impressive results, strongly supporting the development of China's steel industry and other high-temperature industries. The future refractory industry has a long way to go to adapt to the low-carbon development of the steel and other industries, to achieve its own high-efficiency, low-energy, intelligent and green development, and to improve the service level of the industry.
3.1 Low-carbon steel and iron will provide a greater platform for the development of the refractory industry
In the context of the new development strategy of carbon peaking and carbon neutral, China's steel industry will usher in a huge technological change and a new development stage. The scale of China's crude steel production is huge, with a high proportion of long processes and carbon emissions accounting for about 16% of China's total carbon emissions. Green low-carbon development will force the steel process, variety structure, energy saving and emission reduction technology progress. Refractory materials industry to take the initiative to adapt to this strategic transformation of the steel industry, to market-oriented, user-oriented, future-oriented development ideas to achieve their own green low-carbon transformation and upgrading. The next decade, long life, functional, green refractories is the industry's next focus on the direction. Specifically there are :
(1) the development of new technologies for high-temperature industry, metallurgical carbon neutral with key and cutting-edge advanced refractories to meet the new needs of high-temperature industry and low-carbon metallurgy continue to develop. Such as steel smelting breakthrough new technology required for hydrogen metallurgy-related refractories, powder metallurgy key refractories, oxygen-rich blast furnace, ultra-pure steel smelting, low-carbon metallurgy with refractories; cement industry second-generation new dry process and waste treatment with green low energy functional refractories; glass industry oxyfuel process with high-grade oxide and low permeability fusion casting refractories; non-ferrous metal industry oxygen-rich blowing process with Key refractory materials; chrome-free refractories for new coal gasification technology and equipment; refractories for new hydrogen production technology and equipment; new ceramic materials for high-end casting, etc.
(2) Develop new technologies and products with high efficiency and energy saving to meet the needs of high temperature industry to improve thermal efficiency, energy saving and emission reduction. Such as nano-insulation materials, environmental protection fibers and modules, high-quality lightweight thermal insulation bricks, castables, spray coatings, etc., to further enhance the low thermal conductivity, high strength and high temperature resistance of thermal insulation materials and expand the use of lightweight thermal insulation materials; vigorously develop new technologies and new varieties of irregular refractory materials, such as high-performance self-flowing materials, injection materials, press-in grout, plastic spray coatings, and high-quality refractory clay and mastic. Vigorously increase the proportion of application of irregular refractory materials; increase the development of green technology and products of no-burning, low-temperature firing and efficient production, such as functionalized and composite structure prefabricated parts, cast prefabricated bricks, non-burning machine pressed bricks, low-temperature firing bricks, etc., and increase the proportion of low-energy refractory production.
(3) the development and promotion of green and environmentally friendly refractories. Development of refractory materials with environmentally friendly bonding agents to achieve harmless and pollution-free refractories containing carbon; development and promotion of cement lime kilns, non-ferrous smelting furnaces, coal-water slurry gasification furnaces, RH refining furnaces with long-life chrome-free refractories; establishment of refractory testing and evaluation methods for pollutants to achieve green development of refractories from manufacturing, application, pollutant emissions and recycling of used refractories throughout the life cycle.
(4) Development of advanced refractory use technology. Develop high-temperature thickness measurement technology, simulation and simulation calculation and other instruments and software to meet the needs of online monitoring, data collection and analysis, remote diagnosis, and improve the safety and stability of refractory applications. Improve refractories from product to service integration of comprehensive solution capabilities, all-round increase the added value of refractories.
Nowadays, the relationship between refractory enterprises and customers is no longer simple supply and demand. As the high-temperature industry has higher and higher requirements for equipment and supporting materials, customers prefer refractory enterprises to provide refractory design, manufacturing, consulting, construction, operation and maintenance and other complete solutions for thermal engineering equipment. Zhengzhou True Gold has seized this opportunity of transformation to form a harmonious value chain with downstream customers based on turnkey services, establish a good service brand and better meet customer needs.
3.2 Exploring the construction of a refractory powerhouse
For China to become a refractory powerhouse, it needs to make efforts in the following areas.
(1) to increase the joint restructuring efforts, and strive to form 2 to 3 enterprises with international influence, and strive to have more than 3 Chinese enterprises in the top 10 global refractory enterprises, which will make the industry's international competitiveness further enhanced.
(2) Quality stability is further improved, data management penetrates into all aspects of enterprise management, and through data management enterprise, real and efficient management level is achieved, and products are more cost-effective.
(3) Further increase the proportion of investment in R&D, and strive to achieve an industry-wide revenue share level of 2%.
(4) The proportion of indefinite products reaches 50% or more, and the proportion of indefinite products and non-burning products reaches 80% or more.
(5) Steel mills with converters and ladles over 250t have a refractory consumption of 8kg per ton of steel, while other mills have a refractory consumption of 9~10kg.
(6) international and domestic markets to achieve a certain proportion of the double-cycle development model, exports to form a new pattern of exports of refractory products and refractory raw materials side by side.
(7) industry total factor productivity, emission indicators, energy (resource) consumption level to reach the international advanced level.
The next decade, especially the "14th Five-Year" period, is an important window of high-quality development of China's refractory industry. Refractories industry should hold high the great banner of Xi Jinping new era of socialism with Chinese characteristics, based on the new development stage, comprehensive and scientific implementation of the new development concept, in accordance with the "Central Committee of the Communist Party of China on the formulation of the fourteenth five-year plan of national economic and social development and 2035 visionary goals", adhere to the concept of innovation, coordination, green, open and shared development, adhere to the innovation-driven, intelligent manufacturing and green development road. The road of development. With new technology, new equipment, new products and new services as the main line of development, and refractory raw material security upgrade and intelligent digital development of enterprises as the focus, we will comprehensively improve the image of the industry and service level to meet the newer and higher requirements of high-temperature industrial development, actively build a new pattern of refractory industry development, and strive to realize the dream of a strong country in the refractory industry.
