Magnesia Bricks Description
Magnesia Bricks are alkaline refractory materials. These products have over 90% magnesium oxide content and adopt periclase as the principal crystalline phase. Magnesia Bricks can be divided into two categories of Burnt Magnesia Bricks and Chemical Bonded Magnesite Brick. They have excellent performance of superior high temperature mechanical strength and volume stability. Magnesia Bricks can service in the high temperature of 1750.. They are ideal products for glass furnace application.
Magnesia Bricks Features:
It is a kind of alkaline refractory product with periclase as main phase magnesite-alumina spinel clinker as basic material. the product has such characteristics as good temperature vibration, good strength and volume stability in high temperature.

Magnesia Bricks Manufacturing Process
Burnt Magnesia Bricks are manufactured with magnesite clinker as the raw material and fired in the high temperature of 1550~1600 after smashing, burdening, mulling and molding. High-purity products can be fired in the temperature that over 1750. Chemical bonded magnesite brick is produced with certain chemical bonding through mixing, molding and drying.

Product Description: We are a trusted name in manufacturing fire bricks which are a block of ceramic material used in masonry construction. These are sized to be layered with one hand using mortar. Our fire bricks are made from fire clay which is widely used as refractory insulating bricks to maintain insistent temperature. Thee bricks are extensively used in lining furnaces, kilns, fireboxes, and fireplaces.
Magnesia carbon brick isprepared by using high grade fused magnesia and big crystal flake graphite as raw materials,adding compound high efficiency antioxidant and additives,after appropriate grading, moulding and heat treatment process.They are characterized by good oxidation resistance,slagresistance and thermal shock resistance. It can be applied in different parts of steel making equipment,such as converter, electric furnace, refining frnace and ladle.
Magnesia-chrome brick is a high-level refractory product material ,which contains MgO and Cr2O3 as the main components, periclase and spinel are the main mineral components. This type of brick has high refractoriness, high temperature strength, strong resistance to alkaline slag, excellent thermal stability, and certain adaptability to acidic slag. The main raw materials for the manufacture of magnesia chrome bricks are sintered magnesia and chromite. The purity of the magnesia raw material should be as high as possible.
Plant Introduction Sinometal refractory engineering Co., Ltd. is a modern comprehensive enterprise consisting of scientific research, manufacture and trade. Industrial products of the company are mainly magnesia refractories. Products of the company: The company possesses domestic advanced production line of refractories used in metallurgy industry; more than 160 sets of extensive manufacturing facilities; and more than 30 sets of checkout equipment.

Scientific and technical advantages: The company invested a large sum of money to built the building of engineering technology center which covers an area of 5,000 square meters in 2012.The company's capability of scientific research and development is abundant. high refractoriness Brick brief introduction Magnesite Carbon brick is a kind of basic refractory which is made from magnesite, graphite as raw material, resin as binder, with high pressure moulding and low temperature treatment. As one kind of compound refractories, it make magnesite good slag erosion risistance and graphite high thermal conductivity and low dilatability mixed together. Thus BOF Brick has features of high refractoriness, good thermal shock resistance,erosion resistance, and has good performance in I&S industry, including BOF, EAF, LF. basic refractory brick series have the advantages of good performance, long life and low cost. And long supply experience can make sure that we can give our customer total solutions Alumina Magnesia Carbon brick has same production process, the main raw materials are fused alumina or bauxite, so it has better strength and refractoriness under load, but the slag resistance is not as good as magnesia Carbon bricks.
Specifications Mg-C brick has high refractoriess high basic slag resistance good thermal conductivity Magnesia Carbon brick is resin-bonded brick made from dead-burned or fused magnesia and graphite. Anti-oxidant is added if required. Magnesia Carbon brick has good performance in thermal resistance, corrosion resistance and spalling resistance. Widely used in converters, EAFs, ladles and refining furnaces. Magnesia Carbon bricks a very mature product in our area. As our area has 1/4 world storage of best quality Magnesia ore, we can provide as good quality as European Mg-C bricks with competitive prices. We also provide basic refractory lining solution for CONVERTER, EAF, LF, LADLE, etc. these industrial furnaces.
