Product Description

The fused-rebonded magnesia chrome brick has high temperature resistance, good corrosion resistance, thermal shock resistance and bulk stability under high temperature etc .The fused-rebonded magnesia chrome brick is made with sintered magnesia and refractory level chrome ore as raw materials. The space between refractory grains is bonded with silicate.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.

The fused-rebonded magnesia chrome brick mainly used in metallurgy(open hearth,EAF), non-ferrous (metall-urgyfurnace ) , buildings and materials (cement rotary kiln,glass kiln) 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..: 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: How much is magnesium chrome brick a ton?: The price of bricks in different places is not the same. The average price is about 3500 yuan

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.

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

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?: 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.
