Q:Process for producing magnesia chrome brick: The oxide of iron reacts to produce a loose effect caused by the expansion of the spinel. 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. 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?: 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: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: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.

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: Fused magnesia brick brick has compact structure, high mechanical strength,

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: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: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 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.
