The checker work of glass furnaces is subjected to more serious corrosion than the crown and sidewall since all checker bricks are subjected to high temperature, duct and alkali vapor. The plugging and collapsing are the main reasons for the shutdown and cold repair of glass furnaces.
High Refractoriness Magnesite Brick / Magnesia Chrome Bricks For Industry High refractoriness, high basic slag resistance, good thermal conductivity Magnesia Chrome Brick Refractory Magnesia Product Manufacturer ISO9001 Certificate 1.

Rajhans provides world class refractories for copper industry which includes a wide range of direct bonded magnesia chrome (DBMC) bricks (RRL CRVV, RRL CRXS,RRL CRXV, RRL CRXV1, RRL CRVS, RRL DBMC TF, RRL DBMC TF1 etc.) Fireclay / High alumina bricks (RRL 42, RRL H1Al59 etc), alumina chrome (RRL CRAL 10P)), insulating bricks and monolithics.
Direct bonded magnesia-chromite brick is a product made of fused magnesite and chrome concentrate sintered from high purity or secondary purities. It is sintered under high temperature and ultra temperature with fewer foreign materials, where the glass phase is centered in the triangular space and the crystalline phase bonds directly with the
Now in over 100 furnaces worldwide, Emisshield ® works hard to minimize heat loss and increase efficiency. And HarbisonWalker International is the glass industry's exclusive distributor of Emisshield ®. HWI also provides in-house installation services for all Emisshield coatings.*
★ Magnesia Refractory Brick is typical, the ability to resist the strong alkaline slag erosion. ★ Magnesia Refractory Bricks' refractoriness is very high, generally can reach more than 2000 DEG C. ★ Magnesia Refractory Bricks load softening temperature is much lower than the refractoriness, is about 1500 degrees celsius.
Magnesia Chrome Brick is a kind of basic refractory material with more than 90% magnesium oxide content and periclase as the main crystal phase, which has excellent properties of high refractoriness, high temperature strength, good thermal shock resistance and strong basic slag erosion resistance and is mainly used for steelmaking basic open-hearth furnace, electric furnace bottom and wall
Application of Magnesia Chrome Bricks Magnesia chrome brick is mainly used in metallurgical industry, such as building open hearth furnace, furnace top of electrical furnace, out of finery and all kinds of non ferrous smelting furnace. magnesite chrome block is also used in position of burning zone of rotary cement kiln and regenerative chamber of glass kiln.
