- 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 process of firing magnesia chrome bricks is roughly the same as that of magnesia bricks. In order to remove the bricks during sintering, due to MgO and Cr2O3, Al2O3 or direct bonding of magnesia chrome bricks
- 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.
- 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: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 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 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:Magnesia chrome brick
- Magnesia chrome brick to Magnesium Oxide (MgO) and chromium oxide (Cr2O3) as the main ingredient, refractory periclase and spinel as main mineral components of products. The bricks have high refractoriness, high temperature strength, strong resistance to alkaline slag, good thermal stability, and certain adaptability to acid slag. The main raw materials for making magnesia chrome bricks are sintered magnesia and chromite. The purity of magnesia raw materials should be as high as possible, chrome iron ore chemical composition requirements: Cr2O3:30 - 45%, CaO = 1 ~ 1.5%.
- 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: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.
