Some Thoughts on the Development of Abrasives Industry in China

       In recent years, the world economy continued weak recovery trend, the domestic economy into the new normal growth slowed down, China's abrasive abrasive industry is facing a more severe external situation. In the context of the downturn in the market, environmental protection, raw materials, crazy rise and other issues, the development of abrasive abrasive business is even worse, the industry seems to be filled with a sad. More people complain about external factors, but ignored the internal factors, ignoring the industry's own problems. Recently, the original mechanical abrasive abrasive equipment and equipment, Zhengzhou Jin Ye Technology Development Co., Ltd. chairman, enjoy the special allowance of the State Council expert Zou Fujun on the status quo and future development of the industry talked about their views and suggestions.



      I work in the abrasive industry for 55 years, a total of five things done: 1, the first in the industry to develop quality testing equipment, personally produced magnetic tester, audio hardness and so on. 2, the implementation and implementation of the Ministry of Machinery industry self-armed strategy, so that the industry has its own technology and equipment research and manufacturing base, have developed a Chinese-style dry run dry matte wiring, firing kiln, resin sheet forming unit, abrasive processing Machine tool manufacturing, mold sentinel manufacturing, etc. ....... 3, breakthrough in the field of three grinding, to carry out research in engineering ceramics, in the State Council major recrystallization of SiC open tender in the bid, in the country earlier engaged in sintered body, recrystallization, Si3N4 combined with SiC research and production. 4, and industry colleagues with the development of abrasive cleaning production equipment: a blowing machine, subdivision hot air blowing blower, directional broken granulation production line ... ... 5, to carry out environmental dust removal design research. The first in the industry to promote the use of efficient filter cartridge, is still able to undertake large-scale cartridge filter design and manufacturing units. These five things devoted me a lot of effort, 55 years, the initial heart does not change, always obsessed with this let me in the storm through the industry, review the process can not help but think of thousands.





The past 20 years to witness the industry's huge increase in production capacity, the internal structure of self-adjustment. The original ten major subordinate key enterprises gradually fade out of the market, replaced by the vigorous development of private enterprises, disorderly competition smoke filled. What is exciting in this process is that new technologies, new management concepts continue to emerge, relying on their own ability to basically block the previous 70s before the major equipment and technology to rely on imports of the situation, some of China's innovative technologies such as: The appearance of the blowing machine to replace the acid, alkali, washing process, from the abrasive industry, "Made in China" also out of the country, in particular, Jin Ye company launched to blow blow machine as the core of the idea of directional crushing after the technical benefits for the enterprise And the economic benefits of a substantial increase to create the conditions, some enterprises of the abrasive products can also participate in the international market competition in quality, resin wheel forming unit on the basis of the introduction has made a lot of improvements, production efficiency, product quality and automation are international Advanced level. Anthracite instead of petroleum coke smelting SiC and popular in China. However, a considerable part of the abrasive abrasive business is still at a low starting point, backward technology and equipment, weak technical strength of the situation, so far the overall capacity or a serious surplus, low production levels, serious pollution.





A large number of export abrasives are still low prices, high prices into the ordinary abrasive has always wandered in the low-end products, it is difficult to achieve the international advanced level, a large number of export CNC grinding machine in China also need foreign wheel matching, belt grinding machine popular in China The rate is not enough





In short, today's abrasive industry mixed, hi the abrasive industry has become a scale, self-innovation needs and motivation, worry about the adjustment of the national economic structure, the abrasive industry can not be reborn in the fire?





What should be paid attention to is:





1, the abrasive industry environmental issues: Over the years, despite the enterprises and Zhengzhou Jin Ye company in environmental protection dust has done a lot of effective work, but far less than the national requirements and the needs of the development of the situation, companies should attach great importance to and Increase environmental protection investment.





2, the production of abrasive industry, the basis of today's automation is very weak, when to get rid of intensive labor to digital, intelligent production. China's labor resources have not been sufficient and cheap in the past.





3, abrasive non-grinding purposes, large and high value-added products such as: silicon carbide, boron carbide sintered body, α-Al2O3 nano-materials should be vigorously use their own resources to be developed.





4, the proposed abrasive industry entrepreneurs, change the output value than the scale of the concept of subconsciously how to put their own product quality and new product development do better?





Over the years, there are several issues that need to be addressed:





1, why corundum smelting power consumption in the seventies of the last century has reached the 1970 sand, and now the price is so high times, the industry average level of 2500 degrees, is it all because of the quality of bauxite?





2, belt grinding machine is a high efficiency, low cost, high penetration rate of equipment, and now China's belt production has a considerable level and scale, and why the development of belt grinding machine does not come up?





3, now all walks of life have been vigorously developing automated production mode, the state is also vigorously foster intelligent robot industry, why the abrasive industry with a no one workshop? Jin Ye company in Guiyang design and construction of corundum production line, although the industry as Advanced technology, but still did not achieve automation. Imagine: If you want to promote a large area of intelligent production industry, there is no mechanization, how can the realization of automation?





Throughout the status quo, I think there are several points and colleagues need to discuss:





1, the industry must organize a force to engage in a "abrasive abrasive products at home and abroad technical level analysis", on this basis, the "China abrasive abrasive product development plan" to find gaps, clear objectives, so as to effectively participate in international market competition.





2, to strengthen the standardization of abrasive abrasive research and quality supervision level. Standards should be the key, the standard should refer to the international market technical level, combined with China's reality, to develop a basic threshold can stimulate the development of the industry, rather than several manufacturers to open a few to obey the majority of democratic appraisal results. I feel that our standard level is seriously lagging behind, such as: F sand standards, cleanliness standards, wheel organization, hardness and strength ... ...





3, how to further activate the function of industry associations? Now the abrasive abrasive Association work very hard for the enterprises to do a lot of good things, the joint development of the industry is also used the heart, do their best. But after the revocation of the Ministry of Machinery, the industry association to replace some of the functions of the government, how to change in the planned economy model left: the abrasive industry to three subordinate enterprises as the center, unite the whole industry pattern, transformed into a real, The industry, understand the technology, more cohesive industry associations do?





4, the industry needs a research and development institutions. 1984 Department of Mechanical Engineering Zhengzhou three grinding to change the main direction, the abolition of the ordinary abrasive, abrasive, grinding research room, three grinding content has been largely rewritten, but retained the superhard materials and the name, from 1958 to 1984 Industry 26 years of common abrasive abrasive grinding technology to resolve to zero, since then, the industry lost technical support, the National Quality Inspection Center lack of technical guidance, the industry's technology development lost direction. From 84 years to the present 33 years, the size of the industry doubled, but the overall level of improvement is not ideal. Today, witnessed the abrasive abrasive products on the Chinese products squeeze, helpless, industry technology leader I do not know when to form?





In my opinion, I look forward to our industry can be fought, one day flourish, one day we can also for the abrasive abrasive (I have a lot of money, Products of "Made in China" and proud.
