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

Domin inganta juriya na kayan da juriya na shigar azurfa, Cr2O3 ko wani ɓangare na chromium corundum galibi ana ƙara shi zuwa corundum spinel air-permeable tubalin. Cr2O3 da a-Al2O3 suna da tsari iri ɗaya. Cr2O3 ba wai kawai yana inganta juriya na kayan ba, har ma yana haɓaka kushin rigar tsakanin kayan da narkakken ƙarfe, kuma yana haɓaka ƙulli na pores na tubalin da ke numfashi saboda shigar azurfa.

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.

Koyaya, bayan ƙara Cr2O3 zuwa kayan, bayan harbe-harbe ko amfani mai zafi, Cr3+ yana oxide zuwa Cr6+, wanda yake mai guba kuma yana gurɓata muhalli. Don haka, don kiyaye makamashi da kare muhalli, yakamata a guji amfani da Cr2O3 gwargwadon iko, kuma ta maye gurbin albarkatun ƙasa, babban aikin zafin jiki ba tare da ƙara Cr2O3 na iya kaiwa matakin ƙara Cr2O3 ba.

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.
