Zhongtian Hongyuan: converging the tenacity of "Anti-Wear" with Scientific and technological Innovation

In the past 15 years, we have focused on the development and hard work of the rare earth industry, turning the three core technology products of "rare earth thermal barrier coating materials, rare earth alloy wear resistant materials, rare earth surface anti-wear strengthening and remanufacturing" into the forefront of the industry, so that the innovative achievements of rare earths can be transformed into real productive forces, which are widely used in metallurgy, mining, coal, equipment manufacturing, military industry, electric power and other fields. Inner Mongolia Zhongtian Hongyuan re-Manufacturing Co., Ltd. (hereinafter referred to as "Zhongtian Hongyuan" or "the company") is committed to the intelligent operation of mine production lines and the production and research and development of rare earth special alloy steel terminal products. efforts will be made to build a new technology transformation system with the deep integration of academic chain, innovation chain and industrial chain, connecting front-end innovation, upstream materials, mid-stream products and downstream applications. Create rare earth special alloy steel terminal application "whole industry chain cluster".

Strengthen and optimize rare earth anti-wear parts

Three core products

In the middle of winter, Fengshuo is cold, but the furnace in the workshop of Zhongtian Hongyuan rare earth alloy wear-resistant materials is booming and hot. A furnace of molten steel with rare earth waiting for casting is being hoisted through a ladle and poured into a fixed die. The formed rare earth alloy wear-resistant material has higher performance and cleanliness, and its service life can be increased by more than 2 times that of ordinary products. Favored by mining enterprises.

Liu Kangping, deputy general manager of Zhongtian Hongyuan, said that the company has successfully transformed the scientific research achievements of Tsinghua University, Shanghai Jiaotong University, Chinese Academy of Sciences, Inner Mongolia University of Science and Technology and other scientific research institutions in the field of "rare earth alloy wear-resistant materials". Large-scale production of rare earth alloy wear-resistant materials has been realized.

Liu Kangping told reporters: "our series of rare earth alloy wear-resistant and heat-resistant products are key parts of large-scale production equipment in mining and metallurgical enterprises, and they belong to rigid demand products. However, due to the addition of rare earths to our products, our products have higher density, stronger toughness and better performance, the service life can be increased by 1.5 to 7 times, and the performance and indicators have reached the international advanced level. has carried out long-term and stable cooperation with Baotou Steel, Shandong Gold, China Gold, Hebei Molybdenum Industry and other enterprises. "

Walking into the Zhongtian Hongyuan heat treatment workshop, a damaged roll attracted the reporter's stop. This roll from Baotou Iron and Steel Group, by using rare earth welding material to melt its surface and then cladding, a 1cm~2cm coating can be formed on the roll surface. The repaired roll can be reused more than 6 times, and the repair cost is 40% of the cost of buying a new one, but its service life is 3 times longer than that of the new product, which not only saves the purchasing cost of the enterprise, but also saves 70% of the equipment maintenance time.

It is understood that rare earth thermal barrier coatings are coated with rare earth wear-resistant and heat-resistant materials on the surfaces of formed parts, such as bearings, rolls, gearing, etc. the core technology stems from the research results of Dr. Zhao Xiaofeng, a professor of the National Thousand talents Plan and Shanghai Jiaotong University. this technology breaks foreign monopolies, fills the gaps in domestic industries, and is widely used in aerospace, equipment manufacturing and other fields. At present, Zhongtian Hongyuan has become the domestic enterprise with the most complete surface treatment processes, such as ion implantation, powder coating, thermal spraying, laser cladding and so on.

In the field of "rare earth surface anti-wear strengthening and remanufacturing products", Zhongtian Hongyuan combines ion implantation technology with rare earths, through high-energy negative pressure, the elements are ionized to the metal surface, up to 2mm~3 mm, in the metal surface to form new elements, the product life is greatly increased than ordinary coating products, mainly used in aviation, aerospace and other precision parts production, this technology is still the first in China.

"most of the supply relations between our products and cooperative enterprises implement the total contract system, which forces enterprises to increase their R & D and investment in science and technology, and only through continuous innovation and improving the performance and life of their products can they make more profits." Liu Kangping said.

For many years, Zhongtian Hongyuan aims at the transformation of rare earth high-tech achievements and strives to solve the technical problem of terminal application of rare earths in steel. With a clear thinking of development, the use of market-oriented operation means to dredge the difficulties and blocking points of the deep integration of "production, learning, research and use", which has laid a solid foundation for the high-quality development of enterprises. Up to now, the enterprise has obtained 31 innovation patents, of which 2 are national invention patents.

Making rare earth special alloy steel

Terminal application "whole industry chain cluster"

The terminal application of rare earth in steel has always been the technical bottleneck to be broken through in Baotou rare earth industry. Zhongtian Hongyuan is committed to the R & D and production of "rare earth special alloy steel and new materials". Through the four-in-one cooperation mode of "industry-university-research and application", Zhongtian Hongyuan has carried out industrial production of this technology and continuously expanded the scope of application. The reporter came to the production line of rare earth special alloy steel in Zhongtian Hongyuan's whole industry chain. in the spacious workshop, the rare earth alloy steel balls produced one after another climbed and fell along with the conveyor belt like fireballs, making a clanging sound. At present, this is the fifth production line for fully automatic production of steel balls in China, with an annual production capacity of 100000 tons, from front-end smelting to terminal bar rolling and then to tapping balls. In order to seize the market opportunity, the production line was put into production in 2019, but due to financial constraints, it is only put into production at present, that is, the bar rolling stage, releasing only 20, 000 tons of production capacity, while the rare earth alloy steel bar needed for front-end production is mainly purchased from Baotou Iron and Steel Co., Ltd.

Liu Kangping said: "this is only a short-term practice of enterprises." Within five years, we plan to join hands with other private steel mills in Baotou to strengthen cooperation between colleges and enterprises, strengthen innovation, and strive to complete the production line at an early date, so as to gradually form an annual production capacity of 1 million tons of rare earth special alloy steel application products. "

At present, Zhongtian Hongyuan has established a joint R & D center for rare earth special alloy steel and new rare earth materials through cooperation with Baotou material Research Institute of Shanghai Jiaotou University, Baotou rare Earth Research and Development Center of Chinese Academy of Sciences, School of Materials and Metallurgy of Inner Mongolia University of Science and Technology, Inner Mongolia Kyushu State Inspection Center, etc., to provide strong technical support for the enterprise's rare earth special alloy steel industrialization project.

"it is precisely with the support of the scientific research force and the policies enjoyed by enterprises in electric power and taxation, as well as the strong support of scientific and technological innovation support funds and industry support funds, that enterprises dare to transform and develop and challenge themselves. Determined to break new ground in the field of rare earth terminal application." Liu Kangping said.

He told reporters that because the technical level of many domestic parts is not up to the requirements, the relevant parts of many large-scale production equipment are imported, with high use costs and long maintenance cycle, which is bound to increase the operational burden of enterprises in the long run. "at present, through the research and development of rare earth special alloy steel, we are constantly expanding its application fields, developing new products that can compete with foreign countries, changing the situation in which industrial equipment in key areas is subject to human control, and realizing the localization of imported accessories."

"at present, it is the 'spring' of the development of the rare earth industry, we will seize the opportunity, lead with technology, speak with products, actively strive for the relevant support policies of the government at the stage of enterprise production and operation, and make rare earth special alloy steel products bigger and stronger." Liu Kangping said.
