Q:What are the types of magnesia chrome bricks for industrial use?

1. burned magnesia chrome bricks 2. magnesia chrome bricks 3. semi bonded magnesia chrome brick and magnesia chrome brick generally is the three

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:What are the main raw materials of magnesia chrome bricks?

At present the most widely used are magnesium aluminum alloy, followed by magnesium manganese alloy and magnesium zinc zirconium alloy. Mainly used in aviation, aerospace, transportation, chemical, rocket and other industrial sectors. In practical metals, it is the lightest metal, and the specific gravity of magnesium is about 2/3 of aluminum and 1/4 of iron. It is the lightest metal in practical metals, high strength and high rigidity.

Q:Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of high temperature refractory brick?

I produce clay bricks, and my bricks stand at 1500-1700 degrees. Specific depends on what kiln, brick is only part of it

Q:What is a half combination of magnesia chrome bricks?

Direct binding for magnesium magnesium rock stone or periclase spinel crystals, silicate phases were isolated in the grain asked. Half combined with thermal shock resistance than magnesia chrome brick direct bonded magnesia chrome brick, and about half combined with the characteristics of magnesia chrome brick, some physical and chemical indicators. I don't understand, I know there is a production of magnesia chrome brick factory technicians understand this, is known as gold refractory material factory.

Q:How much is magnesium chrome brick a ton?

Magnesium chrome bricks according to physical and chemical indicators in order to know the specific price, the production of magnesia chrome brick place a lot

Q:With different capacitance magnesia brick 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.

Q:What are the environmental hazards of magnesia chrome refractory bricks?

Some of the magnesia chrome bricks will be converted into Cr6+ when used, producing K2CrO4 and other toxic and carcinogenic compounds such as Cr3+

Q:How many kinds of refractory bricks are there?

Magnesia chrome brick: Hang kiln, used for firing zone, the disadvantage is the poor thermal shock resistance, plus six Cr price is highly toxic, the production and use of the national magnesia chrome brick is gradually reduced, the brick production unit as soon as possible to find alternatives.

Q:What is the difference between magnesia chrome brick and direct bonded magnesia chrome brick?

The magnesia chrome bricks are divided into ordinary magnesia chrome bricks, direct bonding magnesia chrome bricks, half bonded magnesia chromite bricks, fused magnesia chrome bricks, fused magnesia semi bonded magnesia bricks, and unburned magnesia chrome bricks
