magnesia chrome brick refractory nozzles and blocks

Magnesia Chrome Brick, Magnesia Chrome Bricks,

Application:

It is made with sintered magnesia and refractory level chrome ore as raw materials. The space between refractory grains is bonded with silicate. The domestic so called magnesia –Chrome bricks.

The refractoriness of magnesia chrome bricks are more than 2000°C,and the refractory under load is a above 1550°C.Good steady volume in high temperature , the performance of meeting sudden cold and sudden hot is better than magnesia bricks.

Q:Process for producing magnesia chrome brick: The fine powder compacts after calcination produced by magnesia - chrome ore grinding method, brick with magnesia coarse particles, are effective measures to eliminate the effect of loose. Compared with the common magnesia chrome brick, the magnesia chrome brick made by this method has lower porosity, higher compressive strength, higher softening temperature and higher flexural strength. Compacts with chrome magnesite powder, magnesia chrome brick by synthetic magnesia chrome sand made of high-temperature calcination, slag resistance and high temperature strength are better than other magnesite chrome brick.In addition, magnesite brick and electric arc furnace melting magnesium chromium material by direct casting (see Figure microstructure, color), fused magnesia chrome brick material produced by the process of melting particles combined with magnesia chrome brick etc..

Q:What are the differences between magnesium chrome bricks, such as direct bonding, re bonding, semi bonding, CO sintering and chemical bonding? Hope expert advice..: Direct bonded magnesia chrome brickThe loose effect caused by the expansion of spinel when the oxide of magnesia brick is directly reacted with the oxide of iron can also be used to make magnesia chromite brick with 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 is a half combination of magnesia chrome bricks?: Opacifying particles as periclase spinel crystal structure, fully developed, as part of account of solution structure and matrix.

Q:What are the environmental hazards of magnesia chrome refractory bricks?: Magnesia chrome brick with MgO and Cr2O3 as the main component of this kind of brick, high refractoriness, high strength, anti alkaline slag corrosion resistance, excellent thermal stability, has certain adaptability in industry wide application of now high temperature acid slag

Q:Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, 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.

Q:With different capacitance magnesia brick brick: Hello, the magnesium chromium brick into common magnesia chrome brick, magnesia chrome bricks, half magnesia chrome brick, magnesia chrome brick, semi fused magnesia chrome brick, unburned magnesia chrome brick, magnesia chrome brick and magnesia chrome brick and directly combined with the distinction lies in 1: containing magnesia (raw material) the purity of 2: the sintering temperature of common magnesia chrome brick sintering temperature at 1550 DEG ~1600 DEG, direct the magnesium chromium brick sintering temperature is over 1700 DEG C, because of its more than 1700 DEG C, magnesia chrome brick, microstructure change and periclase chromium ore directly combined, so called direct bonded magnesia chrome brick. The performance of direct bonding magnesia chrome brick is better than that of common magnesia chrome brick

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: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

Q:Magnesia chrome brick: Magnesite brick and electric arc furnace melting magnesium chromium material by direct casting (see Figure microstructure, color), fused magnesia chrome brick material produced by the process of melting particles combined with magnesia chrome brick etc..

Q:How many kinds of refractory bricks are there?: Dolomite brick: coating performance, good erosion resistance, but how many bricks f-CaO, yasumizu, it is difficult to transport and storage, production with less.
