Features of Ordinary Fireclay Refractory Brick for Export
1) good fire resistance: clay refractory bricks have good high temperature resistance, usually can withstand high temperatures above 1000 ° C, and some can even reach high temperatures above 1500 ° C.
2)strong corrosion resistance: clay and kaolin in clay refractory brick materials contain high silicate and aluminate, can resist a variety of acids, alkali, salt and other chemical corrosion, so it is widely used in chemical industry, metallurgy, electric power and other fields.
