The bearing rings are made of high quality and low oxygen content vacuum degassed bearing steel; the equipment is sophisticated and the heat treatment adopts the multi-purpose furnace production line, which is at the advanced level in China; the product parts are strengthened to improve the surface quality and fatigue strength, which is welcomed by the majority of customers. Our company has a certain share of the rolling mill bearings used by Shanghai Baosteel, Wuhan steel works, Baotou Steel works, Laiwu steel works, Chengde Steel works, Shougang strip steel works, Kungang, Guangzhou Angang, Beiman steel works, Fushun Steel works, Guanggang, guangdai and other units.

Over the years, the company has obtained 41 patent certificates, including 7 invention patents and 34 utility model patents, which have been awarded as Dalian patent demonstration enterprise. The company has more than 100 excellent equipment. The CNC grinder equipment purchased by the company ensures the accuracy of the products. The heat treatment workshop adopts the Austria multipurpose furnace production line, and the whole process computer automatic control. The advanced equipment achieves the world first-class level. The multi-purpose furnace can be bright quenching, gas carburizing and carbonitriding, preventing the workpiece from oxidation and decarbonization during the hot working process. The brand products produced by the company are positioned as the high-end rolling mill bearing market, and the marketing strategy based on the domestic market and focusing on the foreign market and domestic alternative imported bearing market is implemented. In recent years, the bearing of high-speed wire rod mill has been specially developed. The products are widely used in high-speed wire rod, bar, plate, profile and other rolling equipment and rubber and plastic machine equipment in metallurgical industry. The product quality conforms to national standards, international standards and special requirements of customers. The registered trademark of the product is "wzzz". The developed rolling mill bearing occupies a certain advantage in the industry and enjoys a high reputation. Among them, 330661c British four row tapered roller bearing and sealed four row tapered roller bearing have been successfully used in 1700 cold rolling mill of WISCO, replacing the imported ones; 331168a domestic bearing for Xiamen Zhongda bar has been successfully used; idtb0034-2ls with sealed double row tapered roller bearing designed for 2050 vertical hot rolling mill of Baosteel has been successfully used in trial, t-e-48680d / 48620 / 4862 0deiv4 bearing replaced SKF Bearing in Shanghai Baosteel Group and successfully replaced it. It successfully developed sealed double row tapered roller bearing for 2050 tropical vertical roll mill of a steel plant in Shanghai and won the gold medal of international invention pioneer in Nuremberg, Germany. It has been successfully used in many well-known steel mills to replace imported bearings. The research and development of four row cylindrical roller bearing with seal, senjimir bearing, vibrating screen bearing, continuous casting and rolling mill bearing, and the research and development of stamping cage of spherical roller bearing not only prolong the service life of bearing, but also reduce the production cost for users. "Wzzz" products are not only popular in China, but also exported to Austria, Germany, India, Taiwan and other countries and regions, deeply trusted by users at home and abroad.

WaFangDian ZhengDa Metallurgical Mill Bearing Co.,Ltd.

With the recovery of domestic economy, the demand of all walks of life is gradually stronger, and the steel industry is the first to bear the brunt. According to the national policy, we advocate energy conservation and environmental protection, and eliminate backward production capacity. Some small steel mills with serious pollution and backward production capacity have been banned one by one. Instead, the competitive advantages of some large state-owned steel enterprises have gradually emerged. The state proposes to "transform and upgrade the manufacturing industry. The focus of manufacturing industry development is to optimize the structure, improve the quality of varieties, enhance the supporting capacity of the industry, "support the technological transformation of enterprises, and enhance the ability of new product development and brand innovation". Bearing production is an important part of the manufacturing industry, and the large support roll bearing is an important part of the large rolling mill in the rolling industry. "The bearing industry proposes that before the independence rate of major equipment bearing - Comprehensive independence rate reached more than 80%, these large support roller bearings mainly rely on imports, which is a large expenditure of the enterprise. The long-life supporting roller bearing for large-scale rolling mill just fills the gap in China, reduces the cost for steel enterprises and creates profits and taxes for the country. At present, the main enterprises that can produce this kind of products are Wazhou group, Northwest Bearing Co., Ltd. and Beijing Tianma bearing factory. These enterprises have a complete range of products, basically nine kinds of bearings are produced, which can not effectively reflect their professionalism. At the same time, due to the large size of the model, there is no advantage in the price. On the contrary, our company has built its own factory to produce professional products The bearing enterprises of rolling mill are highly professional. At the same time, due to their small scale and flexible management, they are able to solve practical problems for customers according to the quality policy of "your reality, my plan". Therefore, in recent years, the market share of long-life bearings for large supporting rollers has basically reached 5%. The international market situation and the future growth trend of the product, the competitiveness in the international market, and the possibility of substitute import or export of the product.

At present, most of the large steel mills in the international market adopt SKF, FAG and Timken bearing brand products. Generally, the processing cycle is relatively long and the price is relatively high. For European and American countries, most of them will choose such products, but for emerging economies, India, Brazil, South Africa and some Southeast Asian countries often choose to compete with relatively high products from mainland China. With the participation of foreign exhibitions and some domestic bearing exhibitions, more and more foreign customers will know about "wzzz" brand products, which will increase the export volume of the company.



Exported to Austria, Germany, India, Taiwan and other countries and regions, deeply trusted by users at home and abroad
