Development trend of refractory magnesia brick technology

China's economic growth will change from quantitative to qualitative, that is, economic development will no longer rely on high input, high consumption, and high pollution. Magnesia brick manufacturers rely mainly on science and technology. Similarly, China's technological progress is also facing a shift from imitative tracking to independent innovation. In order to achieve leap-forward development, China's scientific and technological personnel need to thoroughly study the development history of science and technology in developed countries in relevant fields, make full use of the existing achievements of developed countries, understand the laws governing the development of science and technology, seize the opportunities of scientific and technological development, and occupy science. The commanding heights of technology.

China's refractory manufacturers, such as the production of refractory materials such as magnesia bricks, magnesium-aluminum bricks, etc., must catch up with the world's advanced level, both to "crowd the car" and "look up and look at the road." "Looking up and looking at the road" will not lose your way; "Put your head and pull the car" to get the job done, and shorten the distance from the developed countries little by little. First, study the trends of developed countries, discuss the technical direction of China's refractory materials; then, analyze the characteristics of the process; then, introduce new scientific and technological resources such as advanced materials, advanced manufacturing, information technology and systems science; finally, introduce the use of this series Resources establish advanced research methods and use this method to develop examples of new refractory materials.

There are three main tasks in refractory process management:

1. Guarantee product quality;

2. Improve existing products;

3. Develop new products.

For developed countries, the variety, quality and use of refractory materials can meet the needs of high-temperature industries, and the demand for improvement and development is not strong. Its main focus is on how to deal with the challenges of low-cost manufacturing countries such as China. To this end, the refractory industry in developed countries has carefully studied the situation in China and formulated countermeasures for “transfer and introduce”.

“Transfer” is the transfer of resource-intensive, labor-intensive or low-value-added refractory products. Reduce production costs and occupy the market in our country. In the 1990s, refractory manufacturers in developed countries entered the country tentatively. After 2000, refractory manufacturers in developed countries began to enter China on a large scale. At present, more than 10 countries and more than 50 refractory joint ventures have produced refractory materials in China. For example, in 2004, the world's refractory manufacturer RHI invested heavily in building an advanced refractory production line in Dalian.

“Introduction” means introducing high-tech into traditional industries such as refractory materials, promoting technological upgrading of traditional manufacturing industries, ensuring technological advantages, and firmly occupying high-end markets, and then gaining leadership (4) (6) and (6) status in the international market. For example, Vesuvius invested a large amount of money to purchase a large number of high-precision, sophisticated equipment, and through a thorough restructuring of the manufacturing process, built a high-level production line to manufacture high-grade refractory materials. On the production line, a 100% sampling inspection of the product is achieved, which significantly improves the reliability of the product. For another example, RHI has a large team of experts who have comprehensively adopted various professional technologies and adhered to research on new refractory materials, refractory raw materials, fire-resistant equipment, control and simulation technology, and achieved many results. For example, high-performance spray robots for converter maintenance.

Compared with developed countries, China's refractory manufacturers have gaps in equipment, technology and product quality, but they have advantages in manufacturing costs.

From the equipment point of view, some well-funded Chinese-funded manufacturers have the ability to purchase some imported equipment to produce some high-grade refractory materials. Other small and medium-sized Chinese manufacturers lack this capability. Typically, general purpose devices are available for purchase. However, special equipment has to be developed by itself. These special equipments have high technical content and low usage, and small companies can't do it. Big companies don't want to do it. A manufacturer has successfully developed it and will not use it for other manufacturers. Therefore, from a general perspective, there will still be a certain gap in the refractory industry in China and developed countries.

Technically speaking, China is fully capable of keeping pace with developed countries. China is a country with a long history and has long advocated education. The Chinese nation is known for its hard work, hard work and hard work. In terms of refractory specialty, the number of universities, the number of institutes, and the total number of technicians in China are more than the total number of graduates and graduate students. Although there are still such problems and such difficulties, as long as they are struggling to catch up, be methodologically and persistently, they will certainly reach or exceed the level of developed countries in the near future.
