COLD ABRASION RESISTANT AS PER THE ASTM-C704

Laboratory instrument for the determination of the abrasion resistance of shaped refractory materials at ambient temperature (UNI EN 993-20) and also for unshaped refractory material (UNI EN 1402-6) Determination of the volume of material abraded from a flat surface of test-piece placed at a right angle to a nozzle through which 1000g of size-graded silicon carbide is blasted by air at 450 kPa.The instrument is manufactured and calibrated to comply with UNI EN 993-20 and ASTM C 704-15.1 Standard and high abrasion

  1. The most common measure of holistic abrasion resistance used to compare refractory solutions is the ASTM 704 test. This test exposes refractory lining materials to a stream of abrasive particulate that cause a portion of the sample to be abraded over time. By keeping sample size and shape constant – along with particle velocity, particle material and test duration – various refractory materials can be compared on an apples-to-apples basis.
