The machine is suitable for the measurement of high temperature wear resistance of refractory products, as well as the determination of relative high temperature wear resistance of refractory castables and refractory plasticity. The equipment refers to the technical requirements of GB / T 18301 "test method for abrasion resistance of refractories at room temperature" (the standard is equivalent to ASTM (c704) standard). The equipment is composed of heating furnace, injection device, air compressor, electronic balance and control system.
