Magnesite Carbon Refractory Brick for Ladle and Refining Furnace

 

Product Description

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.

FAQ

 

Q2: What`s the lead time for my order?

A2: It depends on customers’ requirements and our production schedule. And usually we need 30-60 days for refractory bricks,10-25 days for unshaped refractory materials and 10-20 days for ceramic fiber blankets.

 

Q3: Can you offer Door-to-Door delivery?

A3: Yes, but only for some countries such us U.S., UAE, Saudi Arabia, Iran, and Russia, etc.

Q:Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick or clay brick, which type of high temperature refractory brick?
High alumina brick clay brick up to 1700 degrees above 1500 degrees -1750 degrees of magnesia brick and magnesia chrome brick 1500-1650 degrees, I is the production of clay brick, brick my temperature at 1500-1700 degrees. Specific depends on what kiln, brick is only part of it
Q:What is the ratio of magnesia refractory bricks to brine? For example, what is the difference between the 97 and 95 with 92 brick brick brick material mixed with brine ratio?
Different grades of burned magnesia brick is mainly made of magnesia binder with different taste, there is not a big difference. However, the physical and chemical properties of binders should be controlled well!
Q:The index of magnesia brick
Room temperature compressive strength≥(MPa)(15-25-)24.5-24.5-24.5-24.5-40-40-40
Q:High purity magnesia brick masonry mortar for what?
Always! There is no 800 degrees can be sintered chamotte? As long as the dregs and do not break the aluminum content, the magnesia brick stick together can!
Q:Process for producing magnesia chrome brick
The oxide of iron reacts to produce a loose effect caused by the expansion of the spinel. Also, the magnesia chrome brick can be made from the synthetic common sintered material. In addition, there are non burned magnesia chrome bricks, for example, non burned magnesia chrome bricks combined with inorganic magnesium salt solutions. The unfired magnesia chrome brick has the advantages of simple production process, low cost and good thermal stability, but the strength of the high temperature is far less than that of the burnt brick. In the late 50s, a so-called "direct bonding" magnesia chrome brick was developed. The characteristics of this brick raw material is pure, high firing temperature, periclase and spinel phase with high temperature directly, silicate and other low melting point phase for island distribution, therefore, significantly improve the high temperature strength and slag resistance of brick.
Q:How to identify the fused magnesia brick and sintered magnesia brick
Burnt magnesia brick is made of high quality sintered magnesia as main raw materials, paper pulp as binder. After mixing and high pressure molding, it is fired in a high temperature tunnel kiln over 1550 degrees celsius. It has good thermal stability, corrosion resistance and spalling resistance. Widely used in converter, arc furnace and other industrial furnace lining refractory.Fused magnesia brick brick has compact structure, high mechanical strength, low impurity content, mainly used for the storage of large glass kilnHigh temperature area of the room. The fused magnesia is made of high quality magnesia as raw material. It is made by melting. The English name is fused magnesite. Magnesium hydroxide from magnesite or brucite or from sea water is calcined at high temperature. Strong hydration resistance.
Q:Magnesia brick
General can be divided into sintered magnesia brick (also called burnt magnesia brick) and chemically bonded magnesia brick (also known as the two major categories of not burned magnesia brick). Purity and high firing temperature of magnesia, due to the direct contact of periclase grains, known as direct bonded magnesite brick; made of fused magnesia bricks called electrically fused magnesite brick.
Q:Magnesite chrome brick, magnesia chrome brick indicators? What is the price?.
If you want to know the indicators of chrome brick, magnesia chrome brick must know you are in what furnace above, there is in what position
Q:With different capacitance magnesia brick brick
Fused magnesia brick brick has compact structure, high mechanical strength,It is mainly used for thermal storage of large glass furnaceHigh temperature area of the room.
Q:How to identify the fused magnesia brick and sintered magnesia brick?
Burnt magnesia brick is made of high quality sintered magnesia as main raw materials, paper pulp as binder.
