Interpretation of the Development and Application of Refractories Magnesium-Chromium Bricks in the World

Date of release:2019-03-13 Author: Click:

Ancient, Middle Ages and Renaissance refractories, refractories for blast furnaces, coke ovens and hot stoves before and after the Industrial Revolution, regenerative bricks, new refractories and their manufacturing processes in the late modern times, modern refractory manufacturing technology and major technological advances, as well as prospects for the future development of refractories, refractories and high-temperature technology appear concomitantly, which roughly originated from bronzes. In the middle of the age. In the Eastern Han Dynasty, clay refractories were used as kiln materials and boxes for porcelain firing.

t the beginning of the 20th century, refractories developed towards high-purity, high-density and ultra-high temperature products. At the same time, amorphous refractories and refractory fibers with low energy consumption and no need to be burned at all appeared. Magnesium chrome brick, magnesia brick and magnesia mortar are modern. With the development of atomic energy technology, space technology and new energy technology, refractories with high temperature resistance, corrosion resistance, thermal vibration resistance and erosion resistance have been applied. There are many factories in China that produce refractory products. China has abundant resources, and it is for this reason that major foreign investors have come to China to show their skills and make a show. In the northeast of China, there are abundant refractory suppliers, which has led other foreign investors to question their low export prices. In 2003, the European Union proposed anti-dumping of new refractory products in China, which restricted the export of products to the European Union.

In 2006, in order to protect the massive loss of raw material resources, China exempted some industries from export tax rebates, which greatly restricted the export of products. But this does not restrict the sales of some foreign brands to a large extent, because they have decades or even hundreds of years of sales and production experience, and have greatly occupied the market, but also created their brand effect on various continents.
