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: 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: Brick price?
- There are various series of unshaped refractory gunning, magnesia ramming material, mending material, coating material, dry lining material, composite refining agent, covering agent, tundish and tundish slag wall, ladle drainage sand and electric furnace taphole filler etc..
- 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: Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of high temperature refractory brick?
- The super high alumina brick in high alumina refractory brick has the highest refractoriness, and the corresponding production cost is higher.
- 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: How to identify the fused magnesia brick and sintered magnesia brick
- Magnesia brick have high refractoriness, alkali slag good performance, high load softening temperature, but poor thermal shock resistance. The sintering magnesia brick brick magnesite as raw material, crushing, proportioning, mixing, forming, in 1550 ~ 1600 degrees firing, high purity products firing temperature is over 1750 DEG C. Don't add chemical bond magnesia brick is appropriate in magnesia, through mixing, molding and drying.
- 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: 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: Combined with the ordinary clay brick and magnesia brick as an example, the existence of impurities in minerals and refractories production main components of the formed liquid relative what affect the performance.
- The main varieties of common magnesia brick, magnesia brick, magnesia brick, magnesia brick high pure grade. Product main mineral phase is periclase, volume has high stability and anti erosion ability. Literature is widely used in steelmaking, non-ferrous metal smelting and other high-temperature industrial furnace.
