Fueled by high-temperature industries such as steel, cement, glass, and nonferrous metal in recent years, the output of refractory materials in China climbed to 28.08 million tons in 2010- from 14.77 million tons in 2003-with a compound annual growth rate (CAGR) of 9.6%. According to “Global and China Refractory Material Industry Report, 2010-2011” from Research and Markets, the export volume of refractory products increased substantially, from 827 kilotons in 2003 to 1792.8 kilotons in 2010, with a CAGR of 11.7%.
The steel industry remains the largest sector of refractory materials consumption, at over 65%. The demand of steel-dedicated refractories is directly related to steel output. On a per-ton basis, steel usually consumes less than 10 kg of refractory materials in most? countries, while in China the amount is 20-25 kg. The Development Policy of Refractory Industry estimates refractory consumption of per-ton steel at less than 20 kg in 2010 and under 15 kg in 2020.
Refractory materials for the cement industry, the second largest consumer, mainly cover basic refractory materials (e.g., magnesite brick, magnesite-chrome brick, magnesite-alumina brick, etc.), Al-Si refractory materials (e.g., high-alumina brick, fireclay insulating brick, etc.), and heat insulation refractory materials. While magnesite-chrome brick is most commonly used in the cement kiln firing zone, chromium ion brings about serious pollution at high temperature; magnesite-chrome brick has therefore been gradually replaced by chrome-free refractory materials like dolomite brick and magnesia spinel brick in recent years. Fusion-casting refractories are usually applied in the glass industry and enjoy a 58% share.
