Magnesite chrome brick is one of our major products. Its market share has topped the home market, with a large amount of magnesite chrome bricks being exported to the international market.

Main Product:

☆ Ordinary Magnesite Chrome brick

　　■ Material and Technique: made from sintered magnesia and chrome ore and sintered at high temperature
　　■ Property: having higher bulk density and stronger thermal resistance than the magnesite brick
　　■ Application: used in cement rotary kilns, glass kiln regenerators, permanent lining of steel furnace permanent and refining ladle permanent lining of refining ladle.

☆ Directe-Bonded Magnesite Chrome brick

　　■ Material and Technique: made of low impurity chrome ore and high purity magnesia and fired at high temperature over 1700℃
　　■ Property: strong slag resistance and good performance under high temperature
　　■ Applied in cement rotary kilns, electric arc furnaces, and non-ferrous metal furnaces

☆ Rebonded Magnesite-Chrome brick and Semi-Rebonded Magnesite-chrome brick

　　■ Material and Technique: made with synthetic fused magnesia, shaped under high pressure and fired at ultra high temperature
　　■ Property: Thanks to the high purity of the raw material, the product has good high temperature performance, high thermal resistance, low air-permeability, and strong slag resistance
　　■ Application: used in tapping hole of AOD furnace, the lower vessel of vacuum chamber and snorkel of RH furnace, and the slag line of high temperature furnaces
　　

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 process of firing magnesia chrome bricks is roughly the same as that of magnesia bricks. In order to eliminate the brick during firing, due to MgO and Cr2O3, Al2O3

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 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 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: 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: 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: Magnesium chrome brick price?: Dashiqiao magnesium brick factory of China Building Materials Academy is a joint stock company invested, constructed and managed by China Building Materials Academy.The plant was built in 1992, officially put into operation in 1993, covers an area of 89 thousand square meters, has a long 118 meters, an annual output of 30 thousand tons of high temperature tunnel kiln production line. The group has 1200 employees, 6 senior engineers, more than 20 engineers and technicians, and has strong technical force. Group's total assets of 5.5 million, with an annual output value of 600 million. Profit and tax 65 million yuan.

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?: Opacifying particles as periclase spinel crystal structure, fully developed, as part of account of solution structure and matrix.
