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.
Also known as clay brick brick, is a man-made small bulk building, clay brick clay (including shale, coal gangue powder) as the main raw material, through mud processing, molding, drying and roasting, solid and hollow.
Q:Manufacture of various refractory magnesia brick mainly comes from Magnesium Oxide, what kind of ore?
The ore quality requirements of MgO = 41%, CaO = 6%, SiO2 = 5%. The resources of magnesite in China are rich. The types of deposits include sedimentary metamorphic deposits, sedimentary hydrothermal metasomatic deposits and weathering leaching deposits.
Q:With different capacitance magnesia brick brick
It has good thermal stability, corrosion resistance and spalling resistance. Widely used in converter, arc furnace and other industrial furnace lining refractory.
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: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:Brick price?
Refractory brick series sintered magnesia brick, magnesia chrome brick, magnesia brick, magnesia spinel brick, magnesia calcium brick, unburned magnesia chrome brick, magnesia brick, magnesia calcium brick, magnesia brick, and al2o3-mgo-c bricks.
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:How do you differentiate between the two clearly? Where is the key? Thank you
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 kiln
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
