What forms Mo Laishi firebrick?

Of Mo Laishi firebrick form Molaishi firebrick is main by Mo Laishi photograph (3Al₂O₃ · 2SiO₂ ) composition, in addition the vitreous photograph that still contains certain amount and other a few impurity. Mo Laishi is by alumina (Al₂O₃ ) with 2 oxidation silicon (SiO₂ ) the aluminous silicate that forms by specific scale is mineral, its have exceedingly good high temperature capability and stability.
Bases alumina (Al₂O₃ ) :
Content is in normally 45% to 75% between. The Mo Laishi brick with high content has better high temperature intensity and fireproof degree.
2 oxidation silicon (SiO₂ ) : Content is in normally 20% to 50% between. Supply the essential part that Molaishi forms.
Mo Laishi photograph (3Al₂O₃ · 2SiO₂ ) : Mo Laishi is main brilliant photograph, gift the high temperature capability with good stuff.
Titanium of minim impurity oxidation (TiO₂ ) , ferric oxide (Fe₂O₃ ) , ** is magnesian (MgO) ** . The content of these impurity is general and inferior, but the physics that can affect data and chemistry.
The manufacturing technology of Mo Laishi firebrick
Raw material choice: The aluminous alumina that main raw material is tall purity, silica and material of synthetic Mo Laishi. According to recipe requirement, mix different proportional aluminous alumina and silica.
Smash and mix: Raw material course smashs, abrade and mix, form even powdery makings.
Shape: The powdery makings that will mixed is pressed through working or the honest legal system of extrusion becomes adobe.
Dry: Adobe is dry in oast, the water with redundant purify is divided.
Firing: Adobe is firing in furnace of high temperature kiln, average temperature comes in 1500 ° C between 1700 ° C, make its interior forms stable Mo Laishi photograph.
The main characteristic of Mo Laishi firebrick is tall fireproof degree: Of Mo Laishi firebrick fireproof degree can amount to above of 1790 ° C, suit furnace of kiln of high temperature industry to use.
Good high temperature strength: Higher mechanical strength is had below high temperature, be out of shape not easily and damage.
Exceedingly good heatproof shake sex: The circumstance that Mo Laishi firebrick changes quickly in temperature issues not easy craze, have good thermal shock stability.
Small hot coefficient of expansion: Hot coefficient of expansion is inferior, thermal stability is good, conduce to the stability that maintains kiln furnace structure.
Be able to bear or endure chemical aggressivity: Firebrick has Mo Laishi to fight soda acid goodly to erode performance, suit to be used in chemical aggressivity environment.
Low coefficient of thermal conductivity: The coefficient of thermal conductivity of Mo Laishi firebrick is inferior, conduce to reduce hot loss, improve the thermal efficiency of kiln furnace.
Apply domain iron and steel industry: Use at the high temperature place such as bag of blast furnace, hot-blast stove, steel. Potter course of study: Use at the liner of the kiln furnace such as channel kiln, roller path kiln, shuttle type kiln. Vitreous industry: Use at the kiln pool place of vitreous frit kiln. Cement industry: Those who be used at rotary kiln is firing take and transfer belt. Petrifaction industry: Use at splitting decomposition furnace, change the equipment of high temperature reaction such as furnace.
Mo Laishi firebrick is mixed because of its exceedingly good high temperature capability be able to bear or endure chemical aggressivity, apply extensively in furnace of kiln of industry of of all kinds high temperature.
