Abstract
The distribution and size of in-situ CA6 is related to CAC particle size in CAC-bonded corundum-based castables and would influence the properties of the castables. In order to investigate the influence of CAC particle size on the properties of CAC-bonded castables, CAC was milled for 2â¯h to reduce particle sizes. The properties of CAC-bonded castables with different CAC particle sizes were investigated in terms of demoulding strength after curing at 30â¯Â°C, drying strength after drying at 110â¯Â°C and, in particular, volumetric stability and thermal shock resistance after firing at 1450â¯Â°C, respectively. The results indicate the volumetric stability and thermal shock resistance of the CAC-bonded castables were improved by replacing unground CAC (D50â¯=â¯12.39â¯Î¼m) with ground CAC (D50â¯=â¯1.36â¯Î¼m) because the incorporation of ground CAC produced smaller-sized CA6 with more uniform distribution after firing at 1450â¯Â°C.
