供16目冶金脱氧剂用 碳化硅
碳化硅概述：
碳化硅（SiC）是用石英砂、石油焦（或煤焦）、木屑为原料通过电阻炉高温冶炼而成。碳化硅在大自然也存在罕见的矿物，莫桑石。碳化硅又称碳硅石。在当代C、N、B等非氧化物高技术耐火原料中，碳化硅为应用***、最经济的一种。可以称为金钢砂或耐火砂。 碳化硅是用石英砂、石油焦（或煤焦）、木屑（生产绿色碳化硅时需要加食盐）等原料在电阻炉内经高温冶炼而成。目前我国工业生产的碳化硅分为黑色碳化硅和绿色碳化硅两种，均为六方晶体，比重为3.20～3.25，显微硬度为2840～3320kg/mm2。
碳化硅有黑碳化硅和绿碳化硅两个常用的基该品种，都属α-SiC。①黑碳化硅含SiC约95%，其韧性高于绿碳化硅，大多用于加工抗张强度低的材料，如玻璃、陶瓷、石材、耐火材料、铸铁和有色金属等。②绿碳化硅含SiC约97%以上，自锐性好，大多用于加工硬质合金、钛合金和光学玻璃，也用于珩磨汽缸套和精磨高速钢刀具。此外还有立方碳化硅，它是以特殊工艺制取的黄绿色晶体，用以制作的磨具适于轴承的超精加工，可使表面粗糙度从Ra32～0.16微米一次加工到Ra0.04～0.02微米。
碳化硅由于化学性能稳定、导热系数高、热膨胀系数小、耐磨性能好，除作磨料用外，还有很多其他用途，例如：以特殊工艺把碳化硅粉末涂布于水轮机叶轮或汽缸体的内壁，可提高其耐磨性而延长使用寿命1～2倍；用以制成的***耐火材料，耐热震、体积小、重量轻而强度高，节能效果好。低品级碳化硅（含SiC约85%）是极好的脱氧剂，用它可加快炼钢速度，并便于控制化学成分，提高钢的质量。此外，碳化硅还大量用于制作电热元件硅碳棒。
