磨料及耐火材料
棕刚玉是以铝矾土等为原料,经高温熔炼结晶而成。它具有硬度高,韧性大,颗粒锋锐等特点。用其制成的磨具适用于磨削加工抗张强度高的金属材料。如:碳素钢,一般合金钢,可锻铸铁,硬青铜等。也可以作为耐火材料之用。棕刚玉理化指标:用途 规格 主要化学成分% 磁性物% Al2O3 Fe2O3 SiO2 TiO2 磨料 磨具 F 4#—80# ≥95 ≤0.3 ≤1.5 ≤3.0 ≤0.05 90#—150# ≥94 ≤0.03 180#—240# ≥93 ≤0.3 ≤1.5 ≤3.5 ≤0.02 P 8#—80# ≥95.0 ≤0.2 ≤1.2 ≤3.0 ≤0.05 100#—150# ≥94.0 ≤0.03 180#—220# ≥93.0 ≤0.3 ≤1.5 ≤3.5 ≤0.02 W 1#-63# ≥92.5 ≤0.5 ≤1.8 ≤4.0 — 耐火 材料 段砂 0-1mm1-3mm3-5mm5-8mm8-12mm ≥95 ≤0.3 ≤1.5 ≤3.0 — 25-0mm10-0mm50-0mm30-0mm ≥95 ≤0.3 ≤1.5 ≤3.0 — 细粉 180#-0200#-0320#-0 ≥94.5≥93.5 ≤0.5 ≤1.5 ≤3.5 — 注:F为固结磨具及喷砂用规格P为涂附磨具用规格棕刚玉物理性能: 项目 指标颜 色 深棕(煅烧后深蓝)晶形 三方晶系硬度(莫氏) ≥9.0 熔点(℃) 2250 使用温度(℃) 1900 真密度(g/cm3) ≥3. 90 线膨胀系数(0—1600℃) 7—9 W为微粉,320#即W40
