The most typical method to classify high alumina bricks is by their alumina content material. Below’s a simplified grade reference:
Your gratification is our leading priority. Irrespective of whether you've issues, need assistance, or desire to share feed-back, our focused team is ready To help you every stage of the way in which.
The quantity and properties of your liquid period have a substantial impact about the refractoriness under load. Hence, the reduction on the impurity content material in Uncooked materials is in favor of improving upon the refractoriness beneath load and high temperature creep properties.
High alumina refractories are characterised by alumina (Al2O3) articles between somewhere around 50% to as high as 99%. High alumina bricks are commonly utilized in the course of business in lots of types of programs.
These bricks are made by firing raw elements like bauxite and kaolin at high temperatures, causing a dense, strong item that will withstand Excessive heat and harsh ceramic refractory bricks problems.
Having said that, higher grades tend to be more brittle and high priced. It’s important to match the quality towards your correct furnace disorders—not merely purchase the highest alumina offered.
High alumina bricks are available standardized sizes and shapes, nevertheless customized Proportions are offered for specialized installations.
By prioritizing the categories of high alumina bricks outlined listed here, engineers and procurement professionals could make informed decisions, reducing downtime and routine maintenance prices in industrial options.
Fantastic Corrosion Resistance: The high alumina articles of our bricks offers top-quality resistance to chemical attacks from acids, alkalis, together with other corrosive substances, ensuring prolonged services lifetime and minimal downtime.

Enhanced Actual physical energy and abrasion resistance make phosphate-bonded brick compositions chosen in abrasive programs, such as pebble lime kiln feed finishes and programs that function abrasive dust entrained inside a high-velocity fuel stream.
The alumina bricks producing procedure starts with the cautious choice of high quality bauxite ore, which serves as the primary raw substance because of its high alumina articles and low impurity amounts. All through manufacturing, the bauxite undergoes calcination at temperatures exceeding 1,400°C to get rid of dampness and unstable compounds, developing a secure ceramic material. The manufacturing method carries on with exact grinding and sizing to accomplish exceptional particle distribution, accompanied by the addition of binding brokers and forming additives that enhance workability throughout the shaping stage.
