Introduction to the performance of breathable bricks

Breathable brick is a new product with long lifespan, energy saving and consumption reduction, with reasonable structural design, good thermal stability, erosion resistance, erosion resistance, and permeability resistance, high blow-through rate, safe and reliable operation, and long service life Features.

Slag resistance

Pofuna kukonza slag kukana ndi madzi kukalowa kwakumalako kukana, Cr2O3 kapena gawo la chromium corundum nthawi zambiri limawonjezeredwa ku corundum spinel njerwa zopumira pompopompo. Cr2O3 ndi-Al2O3 ali ndi mawonekedwe amtundu umodzi. Cr2O3 sikuti imangothandiza kuti slag asagwiritse ntchito zinthuzo, komanso imawonjezera mbali yonyowetsa pakati pazinthuzo ndi chitsulo chosungunuka, ndipo imathandizira kwambiri kutseka kwa pores za njerwa yopumira chifukwa cholowera pazitsulo zosungunuka.

Using Cr2O3 fine powder and Al2O3 at high temperature to form a solid solution of aluminum and chromium and an independent chromium-containing glass phase, the liquid phase formed when it comes into contact with the slag in the molten steel smelting process has a certain viscosity, thereby preventing the slag in the molten steel from affecting the air-permeable brick Corrosion; At the same time, it can absorb iron oxide and magnesium oxide in the slag, and form dense spinel in the working layer of the ventilating brick, which improves the slag resistance of the ventilating brick.

Komabe, mutatha kuwonjezera Cr2O3 pazinthuzo, kuwotcha kapena kutentha kwambiri, Cr3 + imakhala ndi oxidized ku Cr6 +, yomwe ndi poizoni ndipo imadetsa chilengedwe. Chifukwa chake, pakusunga mphamvu ndi kuteteza zachilengedwe, kugwiritsa ntchito Cr2O3 kuyenera kupewedwa momwe zingathere, ndipo posintha zinthu zopangira, magwiridwe antchito osawonjezera Cr2O3 atha kufika pamlingo wowonjezera Cr2O3.

Kutentha kwa kutentha kwa kutentha

The main damage method of air-permeable bricks is thermal shock damage. With the continuous increase of the tapping temperature, there is a large temperature difference between working and intermittent work on the working surface of the ventilating brick, which requires the material to have extremely high thermal shock resistance. The spinel phase is introduced into the castable, and the thermal shock resistance of the air-permeable brick will be improved.

The okusayidi kapena sanali okusayidi anawonjezera mu njerwa mpweya amapanga njira olimba njira ndi akaphatikiza pa kutentha kwambiri, kumawonjezera mphamvu kutentha kwambiri njerwa, bwino permeability a njerwa, ndi kukana kukokoloka kwa njerwa mpweya ndi slag wosungunuka mu ladle. Pambuyo pa kutentha kwakukulu kwa kutentha kwa njerwa yomwe imatha kupumira, magwiridwe ake amasinthidwa kuti akwaniritse zofunikira zake.
