Q:How much is one ton of high alumina refractory brick?
High alumina refractory brick according to the different content of AL2O3 is divided into grade, grade one and grade two, and grade three high aluminum brick, Zhengzhou Kang Hui refractories factory price in 800-1900 yuan / ton, stable quality, are exported to the domestic and foreign markets.
Q:How to use the firebrick to build crucible furnace? How to calculate its furnace's width and depth?
1, classify according to the smelting method : Open-hearth furnace steel: Including carbon and low-alloy steel. According to the different lining material, there are acidic and basic open hearth steel two types. Converter steel: Including carbon and low-alloy steel. According to different positions of blowing oxygen, there are bottom blowing, side blowing and BOF steel three types. Electric furnace steel: Mainly alloy steel. According to the different types of electric furnace and electric arc nail fixed Li modified cool boat to raise spending whale steel, induction furnace...
Q:Which is better, the soft core or the hard core?
The wire has two kinds of hard core and soft core, the hard core line is only one wire core, and the soft core line has a plurality of wire cores. For the same sectional area, the 7 core is more than the more than 30 core. There is a difference in use. Generally used for DC is the use of hard core line, because of its small line consumption; and for communication, we should use soft core line, but also in order to reduce its line consumption
Q:What type of refractory brick won't deform or crackbe for a long time in the temprature of about 1600 degrees?
1. , mullite poly light ball brick type, andalusite brick type: MJ-1600 MJ-1700 the temperature is higher than 1600 C. 3, the refractory bricks that won't deform or crack in the 1600 degrees Celsius for a long time includs the following several commonly used bricks: GMZ-80 GMZ-75 the temperature is higher than 1650 DEG C, 2, corundum mullite brick type
Q:Corrosion mechanism of iron on refractory materials
Iron oxide can not be used as refractory,
Q:does 90m high reinforced concrete chimney need firebrick?
The chimney need firebricks or casting fire or acid resisitant concrete after casting, one aim is to resist high temperature, then is to resist acid corrosion. there is a variety of models of the refractory brick , you can refer to the installation quota.
Q:how much is the content of the high alumina of refractory brick?
linear change on reheating is small and Slag resistance is good, matte smelting, good thermal shock resistance used refractory materials should be resistant to high temperature: In front of the furnace, the temperature can reach 1800, copper blowing. The maximum temperature in the smelting furnace area is on the top, pyro-refining and electrorefining, magnesia chrome brick, magnesia chrome castable, magnesia alumina brick. The commonly used refractory materials is direct-bonded magnesia-chrome bricks, which has large volume density. manufacturing technique of copper smelting consists of five parts, Clay brick
Q:High purity magnesia brick masonry mortar for what?
High purity aluminum is 99.99, the first is not pollution, the stove is high magnesia brick masonry, 95% and 97% purity magnesia brick is for a long time did not find a good bit of fireclay, do not know what to build, now used light burned US powder and heavy burned magnesium plus brine built, with 2 months a griddle doesn't stick on magnesium brick, a touch off, there is no good sintering
Q:Mainly use the raw materials inside refractory bricks,
Go to the refractory factory to buy some refractory mortar that has the same texture of refractory bricks, the general boiler use clay refractory mortar.
Q:What are the categories of bricks?
In a proper ratio of lime sand brick and quartz sand, sand or fine sand, the ground, Kazumi Wa, semi dry pressing and autoclaved curing and. The fly ash brick is made of fly ash as main raw material and mixed with cement material such as coal gangue, stone powder or clay. It is made up of batching, molding, drying and roasting. It can make full use of industrial waste residue and save fuel.
