On the afternoon of May 17th,yingkou municipal government and jiachen group,one of China's top 500 enterprises,held a press conference of jiachen ultra-pure magnesia new products and experts BBS at the headquarters of jiachen group.At the press conference,they jointly announced the successful development and production of jiachen group's dense and high-purity sintered magnesia.This product is named"jiachen ultrapure magnesium"by jiachen group.

Magnesia industry in liaoning province‌since 2017,due to factors such as ore,fused magnesia,sintered magnesia and other products of a drop in the product quality,threatening the high quality magnesite industry development,but the pursuit of high quality has been the trend of refractory industry remains the same.At present,the body density of sintered high purity magnesia in China is generally 3.25g/cm3,and the content of magnesium oxide is not stable due to the influence of ore factors.Although magnesia products can be improved by flotation and other means,there has been no feasible solution for the improvement of body density.For many years,the improvement of volume density has been the research focus of generations of refractory workers,and no major breakthrough has been made.The improvement of dense and high purity magnesia to the body density of high purity magnesia developed by jiachen group can be said to realize the long-held aspiration of China's magnesium refractory materials,and the improvement of volume density fills the gap in the market of China's high-grade sintered magnesia.

‌conference,jia Chen group released the news.Spokesman said at the meeting,jia Chen group by flotation natural magnesite and a series of advanced technology in preparation of high purity of the density of sintered magnesia,checked by several authoritative laboratory,magnesium oxide content higher than 98%,the volume density of 3.42 g/cm,physical and chemical performance has with the famous NEDMAG synthetic brine sintered magnesia,jia Chen group with natural magnesite density high purity magnesia raw material production process belongs to the world first,currently involved in the new process,is to apply for a national invention patent.It is known that the international high purity magnesia industry has been difficult to have the presence of Chinese enterprises,jiachen group developed high purity,high density magnesia will break the foreign monopoly.

At present,the dense and high-purity sintered magnesia developed by jiachen group has had stable external supply of 2 vertical kilns,with a daily output of 360 tons of high-purity sintered magnesia.In the later stage,with the gradual completion and production of the project,the annual output is over 1 million tons,and the annual sales revenue is over 10.5 billion yuan,and the profit and tax is over 5 billion yuan.The project makes full use of the original waste resources and USES natural gas calcining,leading the domestic and international in comprehensive utilization of resources,energy conservation and emission reduction,environmental protection and technological innovation.

As for the dense and high-purity sintered magnesia developed by jiachen group in the later stage,its application in the later stage is mainly to replace the cladding wall of ladle brick or replace the common electrofused magnesia.The application area in the later stage is mainly to export to the international market.

May 18 is the 31st anniversary of jiachen group's establishment.It can be said that the successful development and production of dense and high purity sintered magnesia is a tribute to the 31st anniversary of the founding of the group,to the stormy history of China's magnesium refractory industry,and to the 70th anniversary of the founding of new China.

Jiachen group was born in the beautiful land of southern liaoning.Under the leadership of director sun shoukuan,jiachen group has made great efforts and made arduous efforts to develop itself from a small factory with more than a dozen employees,which is unknown to many people,into a large enterprise group with 16 wholly-owned subsidiaries,3 joint-stock companies,assets of more than 36 billion yuan and more than 11,000 employees.
