Features of Magnesia Brick
Magnesia Brick , it is to point to magnesium stone as raw materials, the Israeli magnesium stone as the main crystal phase, MGO style content in 80% ~ 85% or more of the refractory brick. Its products are divided into two categories: Metallurgical magnesia and magnesia products. Magnesia brick is the main products of basic brick, high refractoriness, of alkaline slag and iron slag has good resistance, high refractory brick is a kind of important. Mainly used in open hearth, oxygen converter, electric furnace and non-ferrous metal smelting, etc.
Typical Application of Magnesia Brick
Furnaces of metallurgy industry, heat treatment furnace.
Furnaces of chemical industry and construction industry.
Furnace of incineration of garbage, recirculating fluidized bed furnace .
- Q: What is the difference between corundum and high alumina??
- The main components of high alumina brick are high alumina bauxite, mullite and partial corundum sand.
- Q: Density of high alumina bricks
- Alumina content of 48% or more, mainly from mullite and glass phase or corundum composition of lightweight refractory. The volume density is 0.4 ~ 1.35g/cm3. The porosity is 66% ~ 73%, and the compressive strength is 1 ~ 8MPa. Better thermal shock resistance.
- Q: How to make refractory bricks and boiler wall adhesion more firm?
- Suggest that you use fire brick to increase the length of brick or pull the amount of turn, and use high temperature mortar masonry
- Q: Difference between low creep high alumina brick and ordinary high alumina brick
- The emphasis is on the physical and chemical indexes of low creep and high alumina bricks. The physical and chemical indexes of the high alumina bricks are different, too. They are DRL-1550And LZ-75 perform GB GB/T2988-2012
- Q: Corundum, high alumina and fireclay refractory difference is what
- Corundum is unknown. The high alumina brick has higher aluminum content than the clay brick, and the temperature resistance is higher than 300 degrees. It is more durable and durable than the clay brick. The production process of high alumina brick is better than that of clay brick. For example, the weight of good clay brick is 3.7kg, and that of high alumina is 4.2kg. Good density. But the price of high aluminum is too high: ordinary clay brick (standard brick example) in 1.1--2.5 yuan / block, high aluminum to 4.5 yuan / block, or even more expensive. The extra high aluminum has reached 5000 tons. Say straight white point is: under the same conditions, clay brick for a period of one year, then the high aluminum for more than three years.
- Q: How to test the aluminium bricks of high alumina refractory bricks?
- Forming high alumina brick will be tested on some professional equipment, it is suggested that you can go to the professional testing department to know about it!
- Q: What kind of material is the general metal case?
- Generally speaking, the outer surface of the case is usually made of a steel plate of more than 1 millimeters. The thickness and the material of the steel plate are directly related to the rigidity of the case, as well as the capability of sound insulation and anti electromagnetic radiation. The regular manufacturers of the chassis plate thickness not less than 1.3mm, but there are also some small manufacturers with a thickness of only about 1mm steel, we do not need the ruler to the amount, as long as you put him up, the more weight in the same volume of the chassis is better, in addition, we can also use the finger bomb case shell. If you can hear the crisp percussion sound proof of the casing plate is thin and brittle, if you hear is relatively dull and heavy sound that the chassis material must be good, good general steel plate coated with a layer of thin zinc (bright part), so it can withstand high strength, impact resistance, hardness high elasticity. The frame parts of the chassis are made of high quality materials with high hardness. They are bent into angle shapes or strip shapes. We can shake the chassis frame of the case by hand. Good chassis should be relatively stable, and inferior chassis light is easy to shake. When choosing, we should also pay attention to the outer edge of the case and the edge of the inner bracket. Whether the incision is smooth or not, a good case will not appear in the case of rough edges, sharp edges, burrs and so on. While the poor case appears above phenomenon, often appear when installing the blood splattered". Generally speaking, the chassis must go through the corresponding grinding process before leaving the factory. The edge of the flat plate some burr, edges and corners are rounded, the corresponding fold some corner. When you install such a case, you don't worry about cuts, and some rough, poorly built cabinets tend to scratch your hands.
- Q: How does the physicochemical index change when the high alumina brick is used at high temperature?
- If the range of softening temperature exceeds the load, the constants of other physical and chemical indexes will also increase or decrease.
- Q: What are the categories of bricks?
- Ordinary brick size of 240 mm * 115 mm * 53 mm, according to compressive strength (Newton / square millimeter, N / mm2) size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these intensity levels.
- Q: High alumina brick 80 with which high aluminum cement?
- Which kind should be chosen should be determined according to the conditions of use, life expectancy and cost control. By the way, the quality of masonry is also very influential.
