Not known Facts About 70 alumina fire brick
Wiki Article
High alumina bricks characterize a specialised group of refractory products engineered to withstand Extraordinary temperatures exceeding one,790°C even though retaining structural integrity and chemical security. These bricks have high refractoriness, great thermal shock resistance, and remarkable mechanical toughness, building them ideal for withstanding Extraordinary temperatures and harsh functioning problems. The fundamental attribute that distinguishes high alumina bricks from standard fire bricks lies within their elevated alumina (Al2O3) content material, ordinarily starting from 45% to 90%, which immediately correlates with their Increased effectiveness capabilities.

High alumina refractories are characterized by alumina (Al2O3) articles between about fifty% to as high as ninety nine%. High alumina bricks are greatly utilized through field in several kinds of programs.
five. The thermal shock resistance on the high alumina refractory brick is worse than that on the clay brick, that is intently associated with the mineral composition during the refractory brick. The high alumina brick, for example I, II quality is worse in comparison to the III grade high alumina brick.
Appropriate packaging makes certain product integrity in the course of transit and storage. Underneath are field-standard methods:
Cold crushing toughness represents another significant house, with high-top quality high alumina bricks reaching values exceeding fifty MPa, ensuring structural integrity underneath mechanical loading problems. The refractoriness under load (RUL) demonstrates the brick's skill to maintain structural security although subjected to both of those high temperatures and mechanical pressure, typically starting from one,450°C to 1,520°C determined by composition. Thermal expansion coefficients continue to be relatively lower and consistent, minimizing the chance of thermal stress and cracking for the duration of heating and cooling cycles encountered in industrial furnace functions.
By prioritizing the categories of high alumina bricks outlined here, engineers and procurement supervisors can make knowledgeable decisions, minimizing downtime and maintenance charges in industrial configurations.
High alumina bricks offer a blend of wonderful thermal resistance, abrasion resistance, and chemical security. Their lower porosity and high refractoriness underneath load make them perfect for:
Alumina-primarily based refractorys are an indispensable product for industries that function under Excessive temperatures and harsh ailments. With their unmatched heat resistance, durability, and chemical security, they provide a reputable Answer in your refractory requirements.
