General Information of Magnesite-Chrome Brick

l  CMAX magnesite-chrome brick is made of high quality magnesia and chrome ore.

l  CMAX direct-bonded magnesite-chrome brick is made of low impurity chrome ore and high purity magnesia and sintered at high temperature over 1700.

l  CMAX semi-rebonded and rebonded magnesite-chrome bricks are made partially or fully of synthetic fused clinkers. Magnesite-chrome brick are shaped under high pressure and sintered at very high temperature.

FAQ

Q1: How do you control the products quality?

A1: With strict quality control system throughout the materials selection and production process, our refractory and ceramic fiber products quality is effectively controlled to meet customer requirements.

From the raw materials selecting, our quality control begin. The quality certificates of raw materials are required and each batch will be tested before using. During production, the quality control are conducted by workers and then each piece will be sorted and examined by quality supervis

 

Q2: What`s the lead time for my order?

A2: It depends on customers’ requirements and our production schedule. And usually we need 30-60 days for refractory bricks,10-25 days for unshaped refractory materials and 10-20 days for ceramic fiber blankets.

 

Q3: Can you offer Door-to-Door delivery?

A3: Yes, but only for some countries such us U.S., UAE, Saudi Arabia, Iran, and Russia, etc.

 

Q4: What is the minimum quantity?

A4: There is no minimum order quantity. Depending on the item and processing, there may be a minimum production required, however we can offer a quotation based only on the quantity you need.

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: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 magnesium chromium brick with the direct bonded magnesia chrome brick is different: 1 with the purity of magnesia (raw materials) 2: the sintering temperature of common magnesia chrome brick sintering temperature at 1550 DEG ~1600 DEG, direct the magnesium chromium brick sintering temperature is over 1700 DEG C, because of its more than 1700 DEG C, magnesia chrome brick microstructure occurred change, and periclase chromium ore directly combined, so called direct bonded magnesia chrome brick
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: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: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:Process for producing 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.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:What is a half combination of magnesia chrome bricks?
Semi - combined magnesia chrome brick is a kind of refractory product made from partly fused magnesia chromite sand.
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
