Refractory Bricks Fire Bricks Types Of Refractory

202242 Mostly normal refractory brick created of natural fire clay is as good as acid brick but if additional acid resistance is required then an additional amount of silica is added to on fire clay which may range up to 97 of its composition For binding bases 1 to 2 lime may be added onAcid bricks are burnt at large temperatures for lengthy periods 2 Ordinary Refractory Brick

The production process of refractory materials

20211014 Raw material calcination most refractory raw materials need to be calcined before making refractory bricks This is because their weight and volume will change under the action of high temperature If using the whole raw material to make refractory bricks the volume of the bricks will generally change greatly and even a large amount of deformation and cracking
