Magnesite-Chrome Brick FS-1

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.

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.

Q: What are the environmental hazards of magnesia chrome refractory bricks?: Nowadays, the use of magnesia chrome bricks, especially in cement kilns in the construction industry, has been required to be free of chromium, and the cement products shall not be tested with chromium.

Q: 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.

Q: Magnesium chrome brick price?: Magnesia brick factory with strong technology foundation as the basis, has developed more than 40 varieties of products, including building materials, non-ferrous metals, iron and steel and other fields, won the national high-tech products nearly a dozen, four patents, including magnesia spinel brick reached the world advanced levelFrom July 2006 to now won the high-tech enterprises in Liaoning province; National Standardization Management Committee issued the "adopting international standard product certificate" enterprises; in 2009 passed the ISO9001 quality management system certification; the famous brand products of Liaoning Province certificate certificate and certificate management, the reliable guarantee for the quality of products.

Q: What are the types of magnesia chrome bricks for industrial use?: It is possible to judge by the concrete kiln. The magnesium chrome bricks produced by real gold company are very good. Our factory purchased them the year before last, and their technicians were very professional, and gave us very good suggestions.

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: 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 is the difference between magnesia chrome brick and direct bonded magnesia chrome brick?: The performance of direct bonding magnesia chrome brick is better than that of common magnesia chrome brick.

Q: What are the main raw materials of magnesia chrome bricks?: Magnesium alloys are alloys based on magnesium and other elements. Its characteristics are: small density (1.8g/cm3 magnesium alloy or so), high specific strength, high modulus of elasticity, good heat dissipation, good shock resistance, greater impact load capacity than aluminum alloy, good resistance to organic and alkaline corrosion. The main alloying elements are aluminum, zinc, manganese, cerium, thorium, and a small amount of zirconium or cadmium.
