Refractories in the ancient, medieval, and Renaissance eras, refractories for blast furnaces, coke ovens, and hot blast stoves before and after the Industrial Revolution, new refractories and their manufacturing processes in the late modern period, modern refractory manufacturing technology and major technological advances, and future refractory materials Prospects for development, refractory materials and high-temperature technology appeared together, roughly originating in the middle of the Bronze Age. During the Eastern Han Dynasty of China, clay refractory materials were used as kiln materials and saggers for burning porcelain.
At the beginning of the 20th century, refractory materials developed in the direction of high-purity, high-density and ultra-high temperature products. At the same time, amorphous refractory materials and refractory fibers that do not require firing and have low energy consumption appeared. In modern times, with the development of atomic energy technology, space technology, and new energy technology, refractory materials with comprehensive and excellent properties such as high temperature resistance, corrosion resistance, thermal vibration resistance, and refractory erosion have been applied. There are many factories in China producing refractory products. China has abundant resources, and for this reason, major foreign investors have also come to China to show their talents and show their talents.
Northeast China is an extremely prosperous area for refractory suppliers, causing other foreign investors to question their low export prices. As a result, in 2003, the European Union proposed anti-dumping against new refractory products from China and restricted the products. Exports to the European Union. In 2006, in order to protect the massive loss of raw material resources, China implemented tax rebates for certain industries, thereby greatly restricting the export of products. But this does not limit the sales of some foreign brands to a large extent, because they have dozens or even hundreds of years of sales and production experience, and they have greatly occupied the market and created their brand effects on all continents.
