Product description
Zircon brick manufactured by CH Refractories is a kind of refractory product made of zircon stone as raw material and soft clay as binder. The production process is as follows: the zircon sand is crushed into a group, calcined and then crushed into a suitable particle size, and then mixed by mixing, trapping material, high pressure molding, dry and high temperature firing.
Product characteristics
① High temperature resistance, high strength, wear resistance
② Strong slag resistance, resistance to molten steel, glass solution erosion, erosion ③ small thermal expansion rate, high temperature volume stability
④ Good thermal shock resistance
⑤ High volume density, low porosity, strong permeability resistance
Application
① Steel drum lining for masonry degassing, stainless steel drum lining, continuous casting drum lining, cast brick, plug brick, sleeve brick and high temperature induction furnace lining
② Glass-dense paving bricks or back walls and materials around the feeding port can also be used to contact the glass molten liquid and other parts of the furnace bottom, because zirconite bricks are not corroded by metal chromium aluminum oxide and its slag.
