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

Yo nan lòd yo amelyore rezistans salop materyèl la ak likid likid pénétration rezistans, Cr2O3 oswa yon pati nan krom korundom se anjeneral ajoute nan korindon spinel lè-pèmeyab brik. Cr2O3 ak a-Al2O3 gen menm estrikti kristal la. Cr2O3 pa sèlman amelyore rezistans salop nan materyèl la, men tou, ogmante ang lan mouye ant materyèl la ak asye a fonn, ak siyifikativman amelyore blokaj la nan porositë yo nan brik la rèspirant akòz pénétration nan asye fonn.

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.

Sepandan, apre yo fin ajoute Cr2O3 nan materyèl la, apre yo fin tire-wo tanperati oswa itilize, Cr3 + se soksid nan Cr6 +, ki se toksik ak polye anviwònman an. Se poutèt sa, pou konsèvasyon enèji ak pwoteksyon anviwònman an, yo ta dwe itilize nan Cr2O3 evite otank posib, ak pa ranplase matyè premyè, pèfòmans nan tanperati ki wo san yo pa ajoute Cr2O3 ka rive nan nivo a ajoute Cr2O3.

Rezistans tèmik

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.

Oksid la oswa ki pa Peye-oksid te ajoute nan brik la ayere fòme yon faz solisyon solid ak total la nan tanperati ki wo, ogmante fòs la wo-tanperati nan brik la, amelyore pèmeyabilite ki nan brik la, ak reziste ewozyon an nan brik la ayere pa la fonn salop nan lou a. Apre tretman an chalè tanperati ki wo nan brik la lè-pèmeyab, se pèfòmans li amelyore satisfè kondisyon itilizasyon li yo.
