2 Production of refractories generally follows the sequence ‘raw material processing forming and then firing’ with a variety of forming types available A broad overview of some common refractory materials and their normal service temperatures and compressive strength information is shown below5LMN
Refractories play the triple role of providing mechanical strength protection against corrosion and thermal insulation They are adapted to each specific appliion through finetuning and a careful choice of the different raw materials and their processing Innovative refractory products provide resourceefficient solutions to downstream
1 High refractoriness the refractoriness of aluminium silie refractory plastic can reach to 1750~1850℃ exceed the clay bricks which can be used directly in contact with the flame 2 Good resistance to shock cold and heat it won’t be peel when the
2017430 The principal raw materials used in the production of refractories are normally the oxides of silicon aluminum magnesium calcium and zirconium There are some nonoxide refractories like carbides nitrides borides silies
202242 Magnesia spinel bricks use highpurity magnesia and magnesia alumina spinel as the main raw materials The firing temperature and firing atmosphere are strictly controlled to make it have good flexibility and thermal shock stability kiln skin performance and corrosion resistance The performance exceeds that of highquality magnesia chrome bricks
2 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
