Refractory fire high quality with Japan technology magnesia chrome brick for blast furnace
Magnesium chrome brick is made of high quality magnesite clinker and chromium oxide bonded directly.Through high pressure molding and high temperature sintering, it is characterized by high direct bonding rate and high crystallinity. It has good thermal spalling resistance.Low alkali neutrality makes it have good slag resistance when low acid feed furnace is used.

Features
1. brick with characteristics of multi mineral composition, strong alkalinity, high density.
2. basic refractory magnesia brick is typical, the ability to resist the strong alkaline slag erosion.
3. refractory magnesia brick is also very high, generally can reach more than 2000 DEG C.
4. Magnesia brick load softening temperature is much lower than the refractoriness, is about 1500 degrees celsius.
5. Magnesia brick the thermal conductivity of magnesia brick is good ,low thermal insulation.
6. Magnesia brick thermal expansion, thermal shock stability.
