Preparation of Ceramic Bonded Carbon Block for Blast Furnace

摘要

A new kind of ceramic bonded carbon blocks has been manufactured using artificial aggregate,alumina,metallic aluminum and silicon powder as raw materials in coking process.The results showed that carbon particles bonded with three-dimensional network of ceramic phases were constructed in carbon blocks with the properties improved of mean pore size less than 100nm,＜1μm pore volume greater than 90％,thermal conductivity greater than 30W·m-1·K-1(300°C) and good corrosion resistance.
