Definition Of Basic Refractory Bricks
Basic refractory bricks are containing at least 85% magnesium oxide and one of the most widely used basic refractory bricks. Magnesia refractories are used in a multitude of heat processing industries. These refractories have been extensively used in the steel converter, electric arc furnace and ladle lining in steel-making processes.

Basic refractory bricks for electric arc furnace
Magnesite refractories main advantage is very high slag resistance to lime and iron rich slags. It is very important for steelmaking processes. Currently, magnesite refractories are not only used in metallurgical furnaces, they are also used in glass tank checkers, lime and cement kilns.
Magnesia bricks
Magnesite refractory products have the properties of bearing high temperature, high refractoriness under load and good resistance to alkali. Magnesite refractory bricks are widely used in the basic zone of metallurgical furnaces, non-ferrous furnaces and regenerator of glass furnaces.
Magnesite Alumina Spinel Bricks
Magnesia Spinel refractory bricks possess high-melting point, high chemical inertness against both acidic and basic slags, low expansion values at elevated temperatures and widely used in zones where there is a big temperature change, cement rotary kilns, vacuum induction furnaces, regenerators of glass tanks, lime kilns, continuous casting tundishes, degasser snorkels and lances.
Magnesia Iron Spinel Brick
Magnesia Iron Spinel Brick is an advanced refractory material crafted from a unique blend of magnesia and iron oxide,resulting in a spinel-based structure renowned for its exceptional resistance to thermal shock and chemical corrosion.
Magnesia Chrome Bricks
Magnesite Chrome Refractory Bricks are produced from sintered magnesia and chrome ore by sintering at high temperature. Magnesite Chrome Refractory Bricks have high bulk density and advantages of stronger thermal resistance.
Magnesia carbon bricks
Alumina magnesia carbon bricks are produced from Al2O3 substrates of carbon refractories, high-quality bauxite clinker and appropriate amount of electric melting magnesite. They have good resistance to slag corrosion and thermal shock resistance, a trace of reheating expansion, high temperature stability, no shrinkage, no cracks, no peeling, resistance to erosion, no sticky residue and no pollution to liquid steel.
Magnesia Dolomite Brick
Magnesite Dolomite Refractory Bricks are produced from magnesia that has high purity and density, and sintered Magnesia Dolomite grain. Magnesite Dolomite Refractory Bricks have the advantages of good thermal resistance, anti-spalling performance, good coating protection to the kilns when they are used for cement rotary kilns.

Frequently Asked Questions
Can we visit your company?
+
-
Yes, for sure, you are welcome to visit TOPOWER company and our products. Also, we can talk more about the technique details if you need.
What is the warranty of your magnesia chrome bricks?
+
-
Our products have at least 1 year warranty,if any quality problems, we will take responsibility of the cost of the shipment and the replacement.
What is the role of magnesia in brick?
+
-
Magnesia: A small quantity of magnesia in brick earth imparts a yellow tint to the bricks and decreases shrinkage. But excess magnesia leads to the decay of bricks
What is magnesia brick?
+
-
Magnesia brick is an alkaline refractory brick made of magnesia as the main component and periclase as the main crystal phase. Its magnesium oxide content is 91%-97%. Magnesium bricks have high refractoriness, and have good corrosion resistance to iron oxides, alkaline slag and high-calcium fluxes
Is magnesite a basic refractory?
+
-
Magnesite bricks are extensively used for basic refractories in furnaces. It is a basic refractories brick. Manufactured from fire clay containing 85% of magnesium oxide, 3-5% iron oxide, and the balance lime and alumina. Resists up to 1800℃-2100
What are the refractory properties of mag chrome?
+
-
It is characterized by high-strength, good corrosion resistance and sensitivity to temperature change. The magnesia chrome brick is characterized by high refractoriness, high hot strength, strong resis- tance to basic slag erosion, good thermal stability, and certain adaptability to acid slag.
What are the applications of magnesia refractory?
-
magnesia refractories are used in a variety of applications in steel making processes, from pouring tubes to ladle bricks.
What are the disadvantages of mag C bricks?
+
-
The main issues of using MgO-C bricks are the lower oxidation resistance as well as the poor mechanical strength of graphite which causes loosening of the constituents at high temperature leading to reduced wear resistance as well as resistance to chemical corrosion.
What are the properties of MgO-C bricks?
+
-
MgO-C bricks are composed of magnesia clinker, flake graphite, antioxidants, resin components, etc., and have high resistance to corrosion, spalling, and slag penetration thanks to the characteristics of their constituents.
What is the use of magnesite brick?
-
Magnesite brick has good alkali resistance and is widely used in alkaline open hearth for steel-making, the bottom of the furnace and the wall of furnace
What are the properties of MgO-C bricks?
+
-
MgO-C bricks are composed of magnesia clinker, flake graphite, antioxidants, resin components, etc., and have high resistance to corrosion, spalling, and slag penetration thanks to the characteristics of their constituents.
What is magnesia spinel?
+
-
Magnesium aluminate spinel (MgAl2O4) is an important constituent of magnesia-based refractory materials. The melting point of MgAl2O4 is 2135°C. There are no natural deposits of MgAl2O4, which is therefore normally obtained by reaction of mixtures of magnesium and aluminium oxides.
