Introduction of Sintered Magnesia Brick

Sintered Magnesia Brick is an alkaline refractory material with a magnesium oxide content of more than 90% and periclase as the main crystal phase. Generally, it can be divided into two categories: sintered magnesia bricks (also known as fired magnesia bricks) and chemically bonded magnesia bricks (also known as unfired magnesia bricks). Magnesia bricks with high purity and firing temperature are called directly bonded magnesia bricks because of the direct contact of periclase grains; bricks made of fused magnesia as raw materials are called fused rebonded magnesia bricks.

Magnesia bricks have high refractoriness, good alkali slag
resistance, high load softening temperature, but poor
thermal shock resistance. Sintered magnesia bricks are made
of magnesia bricks. After crushing, batching, kneading and
molding, they are fired at a high temperature of
1550-1600°C, and the firing temperature of high-purity
products is above 1750°C.

Advantages of Sintered Magnesia Brick

1. Magnesia bricks are alkaline
refractory materials, so they have strong resistance to
alkali erosion 2. Strong erosion resistance, high
compressive strength, high refractoriness, can withstand
high temperature without losing structural integrity 3.
High load softening temperature and high purity, magnesia
bricks are usually made of high-purity raw materials to
ensure their quality and consistency 4. Long service life,
magnesia bricks are durable, reducing the cost of frequent
replacement and maintenance 
Sintered Magnesia Brick usage
scenarios Magnesia
bricks are mainly used for steelmaking open hearth furnace,
electric furnace bottom and furnace wall, permanent lining
of oxygen converter, non-ferrous metal smelting furnace,
high temperature tunnel kiln and cement rotary kiln lining,
furnace bottom and furnace wall of heating furnace, glass
kiln Regenerator etc.

Zhengzhou Zhenjin refractory
material CO., Ltd. founded in 1985, is located
in Xinmi City, Henan Province of China. ZHENJIN
REFRACTORIES is a refractory-manufacturing enterprise
integrating research and development, production,
sales, international trade and technical services. The
company is committed to cement industry, glass
industry, non-ferrous smelting and steel & iron
industry to provide products, construction and
installation and tailor services.

ZHENJIN REFRACTORIES has two
lines of burnt basic bricks, one line of alumina-silica
shaped refractory, as well as one line of unshaped
refractory production. There are three super-high
temperature tunnel kilns up to 1850℃, with the total
capacity of about 100,000 tons/annual of various type
refractories. ZHENJIN REFRACTORIES has long focused on
technological innovation and modern equipment
investment, automatic production of programming dosage,
two hydraulic presses of 2500-ton. All the cement
bricks have to pass the multi-functional finishing
line, imported from Europe, in order to sort bricks
beyond the tolerance, to stick card board and to mark
brand.
