Abrasion Resistance(ASTM C704)


In many types of service, refractories are subjected to impact by heavy pieces of material charged into the furnace; abrasion by metallic or nonmetallic solids; or direct impingement by abrasive dusts and high velocity gases.
For greatest resistance to these actions, brick should be mechanically strong and well-bonded. The strongest brick generally show the highest resistance to abrasion. As compared with other properties, the modulus of rupture or crushing test offers the best indication of resistance to abrasion. The abrasion test determines the resistance of a material to erosion when impacted by fine silicon carbide at room temperature. This test is particularly appropriate to applications in which particulate laden gas streams impinge on refractories, or where charge material contacts refractory surfaces at lower temperatures.
