碳化硅

碳化硅是用石英砂、石焦油為原材料在電阻爐內煉制,又稱碳硅石,廣泛用于高科技耐火材料,是經濟的一種,我國生產的碳化硅為黑色和綠色兩種。

用途:

碳化硅由于化學性能穩定,導熱系數高,熱膨脹系數小,耐磨性能好,除作磨料用外,還有很多用途:

1、低品碳化硅(含硅85%)是極好的脫氧劑,可加快煉鋼速度,并便于控制化學成分,提高鋼質量。

2、碳化硅還用于制作電熱元件硅碳棒

碳化硅應用(四大領域)

1、功能陶瓷 2、耐火材料 3、 磨料(用來做磨具,砂輪,油石,砂瓦等)

4、冶金原料(脫氧劑和耐高溫原料)

碳化硅脫氧劑是一種新型的強復合脫氧劑,取代了傳統的硅粉碳粉進行脫氧,和原工藝相比各項理化性能更穩定,脫氧效果好,脫氧時間短,節約能源,提高煉鋼效率,提高鋼的質量,降低原輔材料消耗,減少環境污染,改善勞動條件,提高電爐能源和經濟效益。
