Refractory magnesia brick for glass kiln

Magnesite brick is an alkaline refractory with over 90% magnesium oxide content and the main crystalline phase is Magnesite.Generally can be divided into sintered magnesia brick (also known as burned magnesia brick) and chemical bonding magnesia brick (also known as not burned magnesia brick) two categories.The high purity and sintering temperature of magnesia brick, due to the direct contact of magnesite grains, known as direct bonding magnesia brick;The brick made from electrofused magnesia is called electrofused rebonded magnesia brick.
Magnesium brick has high refractoriness, good alkaline slag resistance, high initial temperature of softening under load, but poor thermal shock resistance.Sintered magnesia brick is made of magnesia brick as raw material, after crushing, batching, mixing and molding, it is fired at a high temperature of 1550 ~ 1600℃, and the sintering temperature of high purity products is above 1750℃.Unpoured magnesia brick is made by mixing, forming and drying with appropriate chemical binder in magnesia.

Features: 

high temperature strength,

high temperature volume stability

strong slag resistance

high refractoriness

Magnesium bricks • Instructions for use
It is mainly used for basic open hearth furnace, electric furnace bottom and wall, permanent lining of oxygen converter, non-ferrous metal smelting furnace, high temperature tunnel kiln, calcined magnesia brick and lining of cement rotary kiln, furnace bottom and wall of heating furnace, lattice brick of regenerative chamber of glass kiln, etc.
