alumina-magnesia
1.Main products made in our factory cover magnesia carbon brick, alumina magnesia carbon brick and carbonless brick and carbonless brick for converter, electric furnace and ladle finer as well as slide plate, pocket block, vent brick and impact plate; pouring materials for converter ladle, gunning refractory for pouring basket, chrome conduction agent, carburant and other unshaped refractory.
2.Guided by Luo Yang Refractory Research In-stitute ,We developed alumina - magnesia spinel car-bon bricks.This product possesses such anvantages as high load softening point ,low porosity,slag-resis-tance and erosion-resistance,When used in the working linings of lable,its effect is evidently raised ,so it is very popular Inmetallurgicol enterprises.
5.THE EFFECT OF MgB_2 AND OTHER MAGNESIA-BASED ADDITIVES ON THE GROWTH ADN MICROSTRUCTURE OF ALUMINA GRAINS
6.Alumina-magensia-carbon unburned bricks are new energy -stving refractory materials,which possess the advan-tages of carbon materials and magnesia - aluminum materials, having such good features as strong slag-resistane,scouring-resistance good heat -stabilitaation and non slay-stained.
7.In the past， Magnesia-Alumina-Spinel bricks were considered as state of the art for chrome-free kiln linings in the cement industry.
8.The influences of different sintering aids,such as magnesia,aluminum, alumina and composite powder of alumina and yttria,with 10wt% addition seperately,on reaction sintered silicon nitride ceramics that were prepared with silicon powder and carbon powder as primary materials were researched under the condition of N 2 flow rate 1.2 L·min -1,nitriding temperature 1380 ℃ and holding time 20 h.
9.Using middle-level magnesia as main raw materials,microsilica,sodium phosphate trimer or calgon as adhesive,925 high alumina cement as solidify additive,chromium micropowder and ultra-fine AlO as micropowder raw materials,the influences on MgO based castables properties of the kind and adding quantity of adhesive,the quantity and adding method of micropowder were researched.
10.Using middle-level magnesia as main raw materials,microsilica,sodium phosphate trimer or calgon as adhesive,925 high alumina cement as solidify additive,chromium micropowder and ultra-fine A1_2O_3 as mending materials micropowder raw materials,the influences on MgO based mending materials properties of the kind adding quantity of adhesive, the quantity and adding method of micropowder are researched.
