Some question about zirconia firebricks

Zirconium oxide refractory bricks have a higher refractoriness than alumina refractory brick, because the zirconia has a higherrefractoriness than magnesia ,alumina and other mineral.So zirconia firebricks have a better performance than high alumina bricks, clay bricks, magnesia bricks, silica bricks and so on.Sometimes, zirconia firebricks' refractoriness can reach above 2200 degrees Celsius.But usually our refractory bricks for steel furnaces don't need such a high refractoriness.We use temperature is generally below 1600 degrees Celsius, so this situation we can enough use alumina firebricks and clay firebicks and some alumina castable can meet the requirements.We are the professional fire bricks manufacturer, we have professional persons to give customers solve various problems in the refractories.If you have any requires, please contact us, we will wholeheartedly serve you.
