For example one study proposed the use of refractory brick waste as supplementary material in cement for use in concrete In addition the use of three types of refractory waste substitutes for silica fume was highlighted and the performance of refractoryadded cement in concrete was found to be satisfactory 25 25 M Zeghad J Mitterpach B
201994 important For example some materials will not tolerate sulphur in the fuel Solid fuels generate particulate matter which will interfere the materials placed inside the furnace For this reason Most furnaces use liquid fuel gaseous fuel or electricity as energy input Induction and arc furnaces use electricity to melt steel and cast iron
A superduty silica refractory brick made from high silica material and an alkaline earth oxide as a bond said brick containing alumina titania and alkalies in a total amount not over about 05 per cent at least one oxide of the group consisting of oxides of calcium magnesium strontium manganese zinc nickel cobalt and ferrous iron
20201027 baxys shutterstock For domestic uses such as ovens barbecue grills and fireplaces the refractory bricks used are usually composed of clay containing mainly alumina and silica elements
2015210 Silica is the refractory of choice primarily because at normal COB operating temperatures silica refractories are subject to minimal creep Also since nearly all of the expansion of silica brick takes place below 650 deg C during normal operation of a COB the moderate temperature fluctuations of the walls have no effect on the volume
