Introduction to the performance of breathable bricks

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

Iji meziwanye nguzogide slag nke ihe ahụ na nkwụsi ike nchara nchara, Cr2O3 ma ọ bụ akụkụ nke chromium corundum na-agbakwụnye na blọk ikuku ikuku permeable corundum. Cr2O3 na a-Al2O3 nwere otu kristal. Cr2O3 abụghị naanị na -akwalite nguzogide slag nke ihe ahụ, kamakwa ọ na -abawanye akụkụ mmiri mmiri n’etiti ihe ahụ na nchara a wụrụ awụ, ma na -emeziwanye mkpọchi nke pores nke brik na -eku ume n’ihi ntinye nke nchara nchara.

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.

Agbanyeghị, mgbe agbakwunyere Cr2O3 na ihe ahụ, mgbe agbapụsịrị ọkụ ma ọ bụ jiri ya mee ihe, a na-etinye Cr3+ na Cr6+, nke na-egbu egbu ma na-emetọ gburugburu ebe obibi. Yabụ, maka nchekwa ọkụ na nchedo gburugburu ebe obibi, ekwesịrị izere ojiji nke Cr2O3 dị ka o kwere mee, na site na dochie akụrụngwa, arụmọrụ okpomọkụ dị elu na -enweghị ịgbakwunye Cr2O3 nwere ike iru ọkwa nke ịgbakwunye Cr2O3.

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.

Oxide ma ọ bụ nke na-abụghị oxide agbakwunyere na brik a na-eku ume na-etolite usoro ihe ngwọta siri ike yana nchịkọta na oke okpomọkụ, na-eme ka brik ahụ dị elu dị elu, na-eme ka ike nke brik ahụ dị mma, ma na-eguzogide mbibi nke brik na-eku ikuku. ntụpọ a wụrụ awụ na ya. Mgbe ọgwụgwọ okpomọkụ dị elu nke brik ikuku na-agafe agafe, a na-emeziwanye arụmọrụ ya iji mezuo ihe ndị ọ chọrọ.
