Product Description

Description:Magnesia hercynite brick is a new generation of large-scale rotary kiln firing zone with chromium-free alkaline refractory material, they have the characteristics of high compressive strength, good thermal shock stability, good thermal creep resistance, resistance to erosion and penetration, and high load softening temperature. At the same time, they are also easier than direct combination of magnesia chrome bricks. the use of iron oxide in magnesium oxide solid melting characteristics using patented hercynite as a raw material, which have better kiln coating effect.

Features:
• The better synthetic purity and activity of self-developed sintered hercynite than fused hercynite's
• Outstanding formation of uniform and stable coating
• Excellent thermal shock stability through the precipitation of spinel in the crystal
• Low thermal conductivity, the outside temperature of kiln shell is between 230~280ºC

Application: Sintering/burning zone of cement rotary kiln.
