China's super hard material industry milestone event

In the 30th anniversary of the birth of China's first synthetic diamond, according to the old experts who closely care about the future development of China's superhard materials industry, the Zhengzhou Abrasives Grinding Research Institute (referred to as Sanmao), in China On the eve of the birth of a synthetic diamond, on November 18-21, 1993, the “China Superhard Materials Development Strategy Seminar” was held in Shenzhen. The industry colleagues responded with enthusiasm and expressed their opinions. They are the superhard materials industry in China. Healthy development, making suggestions. Many experts wrote articles, profound analysis, insightful insights, and covered in the collection of development strategy seminars. Song Jian, State Councilor and Director of the State Science and Technology Commission, said: " Developing high-tech industries to climb new material peaks" ; Minister of Machinery, Zhou Zijian, leader of the project leading group, said: " Play the spirit of socialist cooperation, bravely climb the world The peak of hard material technology, congratulations on the 30th anniversary of the development of China's synthetic diamond industry . At that time, Bai Xiangyin, the minister of building materials department who personally grasped this project, said: " Commemorating the 30th anniversary of synthetic diamonds, 30 years of hard work and industrial diamond development "; Mr. Yuan Yuanjian, who has personally participated in the early research work of Chinese synthetic diamonds, claimed to be a veteran. He wrote a series of papers for the development strategy seminar. He praised the collection as a history book for future generations. The high-level knowledge and thoughts in the super-hard material world are a rich library of wisdom in this field. It is pointed out that as long as all the staff of China's super-hard materials industry work together, make great efforts, and take advantage of the reform and opening up, the Chinese super-hard materials industry Will definitely take off!

A welcome event at the development strategy seminar was the announcement of the list of the first synthetic diamond developers (24 people) in China and published in the front page of the proceedings. What is more gratifying is that 9 of the 21 people who were alive in the past were 9 When people meet, they will meet again after 30 years. It is really rare and they are not self-sustaining.

Shenzhen (93) Development Strategy Seminar is a milestone in China's superhard materials industry. It is a major event in the history of China's superhard materials industry. It has produced and will continue to have far-reaching implications. Every time I recall, I am motivated, the direction is clear, the grooming is clear, and the person who chooses it is briefly described.

First, senior leaders encourage care to specify the direction of careful deployment

The previous instructions of the leading comrades of the Central Committee and the State Council on China's synthetic diamond industry were collected and sorted by Mr. Tao Zhishi, named "friendly encouragement and care", which was published in the first volume.

Entrusted by the respected Premier Zhou Enlai, Li Xiannian, the deputy prime minister who later became the president of the country, as a national leader, he took every opportunity to make a number of important instructions in a timely manner in an industrial sector. give care to indicate the direction, to make arrangements, indeed, commendable, they feel earnest care in these instructions such as:. "to improve product quality, pay close attention to large particles, outreach applications, and to develop products"; "difficulties to despite the difficulties ";" continue to catch it, you can always catch the good quality and good quantity ";" to mobilize the masses, strengthen leadership, lessons learned, so that it will soon improve product quality, variety and development ";" just make big If power can be done, it should be done ; "The foothold should be based on one's own production, and relying on oneself is the only good way ."

These instructions, affectionately, are the marching orders, the rudder, the materialism, and the dialectic, which is the guarantee that we continue to move from victory to new victory.

Second, the various disciplines and legions of the various disciplines vigorously cooperate with the triumphant

The development of synthetic diamonds in China began in the early 1960s. At that time, the Ministry of Machinery Industry, the Academy of Geological Sciences, and the Chinese Academy of Sciences formed a number of roads. They were blocked by technology and could not be used for reference. They started from scratch, and the country was in urgent need of heavy construction. Under the circumstances that we can only understand the difficulties, we will give full play to the ingenuity and wisdom of our scientific and technological personnel, work together, unite and fight, and climb bravely. .

After more than two years of hard work, the General Machinery Research Institute of the Ministry of Machinery Industry, the Sanma Institute and the Geological Science Research Institute of the Ministry of Geology worked together on December 6, 1963, at the domestically produced 300-ton 61-type two-sided anvil ultra-high pressure device. On the high-purity graphite powder as the raw material, nickel-chromium alloy as the catalyst, at the conditions of 78,000 GPa and 1370-1550 ° C, the first synthesis was successful - China's first synthetic diamond was born, played a socialist The great collaboration of Kaige! For this purpose, the domestic two-sided anvil ultra-high pressure device has made a historic contribution to China's synthetic diamonds. On this historic day of victory, it is like a star-studded month, Qi claimed it, and the colleagues agreed to Listed as the first item in the memorabilia of this symposium, more than ten experts and scholars have repeatedly mentioned in their respective essays and this day that is forever included in the history of the development of superhard materials in China. The day of the celebration.

Third, the quantity is high quality, the quality is the first, the quality is high and the stability is two-pronged.

To be among the strongest countries, the quantity is important; the product has characteristics, and the quality has the advantage. It is also a prerequisite. The quality should be high and stable, that is, the R&D starting point is high, aiming at high-intensity and large-particle products, and it is easy to receive 'call. In fact, the law has its effect; normal production must strive for stable product quality, easy to win the user's peace of mind, and firmly occupy the market.

Four, two sides, six sides and each have their own strengths to promote mutual development

In 1965, the Institute of Foundry and Forging Machinery, Sanmao Institute and Shanghai Materials Research Institute jointly undertook the intermediate test task of synthetic diamonds issued by the Ministry of Machinery Industry. The three divisions worked together and completed the task well. The installation was completed in August of this year. China's first 6×6MNDS-023A hinged six-face press was born in Jinan. Then the test was carried out while the test was carried out. The press was then transported to the Sanmao Institute. On July 3, 1966, it was officially put into the synthetic process test. The original production of 10,000 carats of synthetic diamonds was urgently needed by the country and was the first in China. The professional manufacturer of synthetic diamonds, the sixth grinding wheel factory and many other manufacturers, laid the foundation for technology. From then on, it shows the prosperous scene of chasing each other and promoting common development in China's two sides and six sides!

Regarding the relationship between the two sides and the six sides, Mr. Yao Yucheng has a deeper understanding of this aspect. He pointed out that the development of the two sides of China is difficult, and the development of the six sides is always a survival for the competition. Leading. Over the years, the technical difficulty of the two sides has been underestimated, and the process potential of the six-face top and the ability to adapt to the domestic environment have not been adequately analyzed. However, it should be affirmed that it is correct to use a large two-sided roof to solve the high-end diamond route in China, but it is too easy to be too optimistic. The relationship between the two sides and the six sides is most likely to be mutually reinforcing and developing together.                                                                                

5. Synthetic cavities tend to be large. Top hammer cylinders are the key

The large-scale trend of synthetic cavities is inevitable. Although the problems to be solved are multi-faceted, it is undeniable that the top hammer and the pressure cylinder are the key ones. Every step of China's superhard materials, the hard alloy of this aspect, has contributed. The synthetic cavity is going to be large, and in this process, this aspect of the army will continue to have much to offer.

Sixth, the products are aimed at the market, with various varieties and different characteristics.

The development of superhard materials is driven by the application of superhard materials. Our current situation is that product development is relatively lagging behind and has become a weak link in the development of superhard materials. We should aim at the market to develop products, to develop more varieties, and to have different characteristics to adapt to the diversity of social needs, which in turn will promote the development of superhard materials.

Seven, the application of research internal use of weak links need to work hard

Strengthening the research of applied technology is not only conducive to the rapid promotion of the application range of super-hard materials, but also the driving force for the continuous development of super-hard materials. Our current situation is that application technology research has lagged behind, and it has become a weak link in the domestic use of products.

8. The enterprise group strives to form an international market to participate in the competition.

According to the requirements of modern industrial production and the characteristics of superhard materials industry, it is an inevitable trend to form a corporate group. We must focus on implementation; we can also form a consortium of scientific research institutions, manufacturers and users to enhance their participation in international competition.

Nine, enterprise management macro-control objective needs industry association

It is necessary to strengthen enterprise management and do a good job in macroeconomic regulation and control. The reality of China's superhard material industry development is that it requires both the conditions for establishing a national industry association.
