Refractory raw materials Silicon Carbide in the new situation of China development strategy seminar, standing vice President of China association Xu Dianli resistance when there is a problem report in Silicon Carbide series refractory raw material, he said: silicon carbide refractory clay resource configuration is not reasonable. Now the world's proven 49 aluminum refractory clay resources country, but with diaspore monohydrate (refractory materials required to produce the high quality raw materials) only China and Guyana, other countries are sanshui diaspore (alumina required to produce the high quality raw materials).
Silicon carbide series in China has a wide distribution of raw material, 3.753 billion tons of bauxite, clay minerals, 2.458 billion tons, shanxi, henan, guangxi and guizhou province accounted for 91.13% of the total reserves. Although the resources is abundant, but for a long time of mineral resources planning is not reasonable, development and protection, mining, destruction and waste phenomenon is more serious, the unreasonable planning not only caused the waste of resources, also affect the refractory industry industry security. From another point of view, if the refractory raw materials resources required for industrial production
About the refractory Silicon carbide development trend in the future, he said: demand is falling. Iron and steel, nonferrous metal, cement, glass and other products demand after 2000 years of rapid growth, now serious excess capacity, in the future will quickly decrease in new projects, fire-proof material demand will be significantly lower. Consumption will decline gradually. The current iron and steel industry overall contracting refractory material consumption has fallen to about 15 kg/t steel, new dry process cement kiln refractory consumption has fallen to 0.5 kg/t clinker, float glass furnace life is basically achieved the level of 8 years. Domestic refractories demand will drop to 24 million tons. If exports remain in 2 million tons, the total annual production will remain at around 26 million tons.
