magnesia hercynite bricks

タイトルまたは説明

The Cr3+ in magnesia chrome bricks will change into Cr6+ in the condition of high temperature and alkali; the consumption of magnesia chrome bricks in burning zones is **0—**0 thousand tons per year, and the consumption of waste magnesia chrome bricks is **0—**0 thousand tons per year. The Cr6+ content in waste magnesia chrome bricks also reaches 0.1—0.5% and remains unprocessed.

The development of magnesia hercynite bricks ends the status that China lagged behind the US and Europe for *0 years in the chrome-free refractory for cement kilns, and can decrease the chrome pollution by a big margin.

With good refractoriness under load, high temperature intensity, corrosion resistance, thermal shock stability and crusting, the magnesia hercynite bricks have been applied in over **0 production lines of over *0 cement enterprises, reaching good operating effect and good reputation among customers.

The magnesia hercynite bricks have the following characteristics:

Fast crusting, firm crusting, stable crusting, corrosion resistance without alkali-crack and loosening, low kiln surface temperature from **0℃to **0℃which is over *0℃lower than some foreign magnesia hercynite bricks, and remarkable energy conservation.
