Low creep high alumina brick for hot blast stove

Low creep and cigle visoke glinice are high-grade refractory materials made of alumina, fused corundum, and fused mullite as the main raw materials.

Značajke

1. Vatrostalnost

The refractoriness of low-creep and high-alumina bricks is higher than that of clay bricks and semi-silica bricks, reaching 1750~1790℃, which is a high-grade refractory material.

2. Napunite temperaturu omekšavanja

Budući da proizvodi s visokim sadržajem glinice imaju visok Al2O3, manje nečistoća i manje topljivih staklenih tijela, temperatura omekšavanja opterećenja viša je od temperature glinenih opeka. Međutim, budući da kristali mulita ne tvore mrežnu strukturu, temperatura omekšavanja opterećenja još uvijek nije tako visoka kao kod opeke od silicijevog dioksida.

3. Otpor troske

Low creep and high alumina bricks contain more Al2O3, which is close to neutral refractory materials, and can resist the erosion of acidic slag and alkaline slag. Because it contains SiO2, the ability to resist alkaline slag is weaker than that of acidic slag.

koristiti

Mainly used for lining of blast furnaces, hot blast furnaces, electric furnace tops, blast furnaces, reverberatory furnaces, and rotary kilns.
