Hengjia high-purity alumina high-end raw materials and refractory technology exchange meeting was successfully held in Gongyi, Henan

On November 19, 2019, Shandong Hengjia High Purity Aluminum Technology Co., Ltd. (Hengjia High Purity 873086) successfully held the "Alumina High-end Raw Materials and Refractory Technology Exchange Conference" at Huayu International Hotel in Gongyi City, Henan Province. The purpose of this conference is to promote technical exchanges and cooperation among domestic refractory companies, deepen industry understanding and innovative development, and promote continuous progress in the field of refractory materials. Experts and scholars from many well-known scientific research institutes such as Zhengzhou University, Wuhan University of Science and Technology, and Sinosteel Luoyang Refractory Materials Research Institute, as well as more than 80 companies and more than 170 industry professionals from Henan Province and surrounding areas gathered together to discuss the scientific research progress and technical applications of alumina refractory raw materials.

At the beginning of the meeting, Mr. Li Hongchao, Sales Manager of Hengjia High Purity, introduced the guests and senior leaders of the company. On behalf of the company, Mr. Wang Yongting, Sales Director, extended a warm welcome to all the guests and expressed sincere gratitude to the customers and friends who have long supported the development of Hengjia High Purity. Mr. Wang pointed out that the Hengjia High Purity Technology Exchange Conference has been successfully held for three sessions, and this return to Gongyi is of great significance. Since the establishment of the company, Hengjia High Purity has always adhered to the concept of "perseverance, pursuit of stability, high quality, and creation of excellence", and gradually expanded from the domestic market to the international market, with a rapid business growth trend.

Director Wang Yongting gave a detailed introduction to the development achievements of Hengjia High-Purity in recent years. Sales in 2019 are expected to achieve a year-on-year growth of 50% to 200 million yuan. At the same time, the company's production capacity in the alumina field has continued to expand, and a series of new products such as plate-shaped corundum for breathable brick cores, hydrated alumina and high-purity spinel have been launched one after another. The annual production capacity has reached 100,000 tons, and remarkable results have been achieved.

The technical sharing session of this exchange meeting was hosted by Chen Zhiqiang, technical director of Hengjia High Purity. Professor Ye Fangbao from the Institute of High Temperature Materials of Zhengzhou University, Professor Wei Yaowu from the School of Materials and Metallurgy of Wuhan University of Science and Technology, Professor Zhang Sanhua from Sinosteel Luoyang Refractory Research Institute Co., Ltd. and many other industry experts gave in-depth explanations on the research progress of refractory materials.

Professor Ye Fangbao, with the topic of "The influence of micro powder on the rheological behavior of pumped castables", elaborated on the rheological characteristics of pumped castables in detail, and through experimental analysis, revealed the key role of micro powder particle size, particle morphology and activity on castable performance. He emphasized that controlling rheological characteristics is an important way to optimize pumping effects and improve construction efficiency.

Professor Wei Yaowu gave a lecture on the thermal shock stability of corundum castables, pointing out that thermal shock stability is one of the most critical properties of refractory materials. Through different test methods such as heating and air cooling, Professor Wei provided a scientific analysis of the performance of corundum castables under extreme temperature changes, further optimizing the performance of the castables.

Professor Zhang Sanhua from Luoyang Refractory Research Institute brought a study on the application of spinel in corundum-spinel castables. Spinel has become an important component in refractory materials due to its high melting point and strong slag resistance. Professor Zhang demonstrated the amount of spinel added and its effect on material properties through experiments, further verifying the key role of spinel in refractory materials.

In addition, Dr. Li Zhigang of Zhengzhou Kexin Furnace Material Co., Ltd. and Dr. Bi Zhenyong of Henan Haiger High Temperature Materials Co., Ltd. also conducted in-depth discussions on the innovation and performance improvement of Al2O3-SiC-C castables and the technical development direction of aluminum-magnesium refractory materials, providing a full range of technical perspectives for the guests.

The climax of the meeting was the special sharing by Mr. Shao Changbo, Chairman and General Manager of Hengjia High Purity. He reviewed the development history of Hengjia High Purity over the past six years and introduced in detail the company's innovative achievements and technological breakthroughs in the field of refractory raw materials. Mr. Shao focused on the application of calcined alumina micropowder and activated alumina micropowder in refractory materials, especially the excellent performance in iron ditch castables and ladle castables. He also demonstrated the AM-78 high-purity magnesium-aluminum spinel developed by Hengjia Company, emphasizing the excellent performance of the product in high-temperature strength, thermal shock stability and hydration resistance, which was highly recognized by industry experts and customers.

Hengjia High Purity not only makes continuous breakthroughs in technology research and development, but also strives for excellence in quality control. Since 2014, the company has invested more than 8 million yuan to build an alumina refractory raw material research and development center, equipped with more than 40 advanced testing instruments such as XRD, XRF, SEM, BET, etc., which can conduct online testing of raw materials to ensure the stability and consistency of products.

This technical exchange meeting not only provided participants with rich academic and technical content, but also built a communication platform for Hengjia High-Purity and domestic and foreign customers. Through in-depth technical discussions and interactions, Hengjia High-Purity further understood market demand and customer expectations, laying a solid foundation for future product innovation and optimization.

As a private enterprise, Hengjia High Purity has been moving forward steadily in the fierce market competition, always adhering to the close integration of technological innovation and market demand. In the future, Hengjia High Purity will continue to uphold the spirit of "professionalism, concentration, single-mindedness, and excellence", and strive to become the world's leading supplier of alumina-based refractory raw materials, contribute more to the high-quality development of the refractory industry, and help Chinese refractory materials stand out on the global stage.
