我(wo)廠銷(xiao)售石墨粉(fen)含量在80—90%【固(gu)定碳(tan)】，適用于(yu)煉鋼、鑄造(zao)、潤滑(hua)工業。石墨粉(fen)具(ju)有化學性穩定，不受強酸堿影響，有害雜(za)質(zhi)少，鐵(tie)硫含量低，具(ju)有耐(nai)高溫、傳熱、導電(dian)、潤滑(hua)及可塑性，廣泛用于(yu)鑄造(zao)、涂(tu)模(mo)、電(dian)池、碳(tan)素(su)制品、鉛筆(bi)、及顏料、耐(nai)火(huo)材料、治煉增碳(tan)劑等。

　　1做耐火材料

　　石(shi)墨的一個主要用途是生產耐(nai)火材料，包括耐(nai)火磚，坩堝，連續鑄(zhu)造粉(fen)，鑄(zhu)模(mo)芯，鑄(zhu)模(mo)洗滌劑和耐(nai)高溫材料

　　坩(gan)堝(guo)及(ji)有關制(zhi)(zhi)品(pin)用石墨(mo)制(zhi)(zhi)造的(de)成型和耐(nai)火的(de)坩(gan)堝(guo)及(ji)其(qi)有關制(zhi)(zhi)品(pin)，具有高耐(nai)火性(xing)(xing)，低的(de)熱(re)膨脹(zhang)性(xing)(xing)，熔(rong)煉金(jin)屬過程中，受(shou)到金(jin)屬浸潤 和沖刷時亦穩定(ding)，高溫(wen)下好(hao)的(de)熱(re)震穩定(ding)性(xing)(xing)和好(hao)的(de)熱(re)傳(chuan)導性(xing)(xing)，所以石墨(mo)坩(gan)堝(guo)及(ji)其(qi)有關制(zhi)(zhi)品(pin)被(bei)廣(guang)泛(fan)用于(yu)直接熔(rong)融金(jin)屬的(de)工(gong)藝中

　　2煉鋼

　　石(shi)墨(mo)和其他雜質(zhi)材料用于(yu)煉(lian)鋼工業時可作為增碳(tan)劑。滲碳(tan)使用的(de)(de)碳(tan)質(zhi)材料的(de)(de)范圍很(hen)廣，包括人造石(shi)墨(mo)、石(shi)油(you)焦(jiao)、冶金焦(jiao)炭。在世(shi)界范圍內煉(lian)鋼增碳(tan)劑用石(shi)墨(mo)仍是土狀石(shi)墨(mo)的(de)(de)主要用途。

　　3作導電材料

　　石(shi)(shi)墨在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)工(gong)業中廣泛用來作電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)刷、碳棒、碳管(guan)、整流器的(de)(de)正極、石(shi)(shi)墨墊(dian)圈、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)話(hua)零件、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)視機顯像管(guan)的(de)(de)涂(tu)層等(deng)等(deng)。其中以石(shi)(shi)墨電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極應用廣，在冶煉各(ge) 種合金(jin)鋼、鐵(tie)合金(jin)時，使(shi)用石(shi)(shi)墨電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極，這時大的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流通過電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極導入電(dian)(dian)(dian)(dian)(dian)(dian)(dian)爐的(de)(de)熔煉區，產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)弧，使(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)轉(zhuan)化為熱(re)能(neng)，溫(wen)度(du)升高(gao)到2000度(du)左右，從而達到熔煉或反 應的(de)(de)目的(de)(de)。此外，在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解金(jin)屬(shu)鎂、鋁、鈉時，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解槽(cao)的(de)(de)陽極也用石(shi)(shi)墨電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極。生產金(jin)剛(gang)砂的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻爐也用石(shi)(shi)墨電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極作爐頭(tou)導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)材料(liao)。

　　4作(zuo)耐(nai)磨(mo)和(he)潤滑(hua)材(cai)料

　　石墨(mo)在(zai)(zai)機械工業中常作(zuo)潤(run)(run)滑(hua)(hua)(hua)劑。潤(run)(run)滑(hua)(hua)(hua)油往往不(bu)能(neng)在(zai)(zai)高(gao)速(su)、高(gao)溫、高(gao)壓(ya)的條件下使(shi)用(yong)，而(er)石墨(mo)耐磨材料可以在(zai)(zai)-200---2000溫度并在(zai)(zai)高(gao)的滑(hua)(hua)(hua)動(dong)速(su)度下不(bu)用(yong)潤(run)(run)滑(hua)(hua)(hua)油工作(zuo)。許多輸送腐蝕(shi)介質的設備，廣(guang)泛采用(yong)石墨(mo)材料制成(cheng)活塞環、密封圈和軸承，它們運(yun)轉時(shi)，勿(wu)需(xu)加入潤(run)(run)滑(hua)(hua)(hua)油，石墨(mo)乳也(ye)是金屬加工（拔絲、拉管）時(shi)的好(hao)的潤(run)(run)滑(hua)(hua)(hua)劑。

　　5作耐腐蝕材料

　　石(shi)墨具(ju)有好(hao)的(de)化(hua)學穩定性。經過(guo)特殊加工的(de)石(shi)墨，具(ju)有耐腐蝕(shi)、導(dao)熱(re)性好(hao)、滲透率低等特點，而廣泛用(yong)(yong)于制作熱(re)交換器(qi)、反應槽(cao)、凝縮(suo)器(qi)、燃(ran)燒塔(ta)、吸收塔(ta)、冷卻器(qi)、加熱(re)器(qi)、過(guo)濾器(qi)、泵(beng)等設備。這些設備用(yong)(yong)于石(shi)油(you)化(hua)工、濕(shi)法冶金、酸堿生產、合成纖(xian)維、造(zao)紙等工業部門(men)，可節省大量(liang)的(de)金屬(shu)材料(liao)。

　　6作(zuo)鑄造、翻砂(sha)、壓模及高溫冶金材料

　　由(you)于石(shi)墨(mo)的(de)(de)膨脹系(xi)數小，而(er)(er)且耐急冷急熱的(de)(de)變(bian)化，可作為玻璃器皿的(de)(de)鑄模，使(shi)用石(shi)墨(mo)后，黑色金屬(shu)得到(dao)的(de)(de)鑄件尺寸，表面光潔，成品(pin)率高(gao)，不經(jing)加工(gong)或稍作加工(gong)就可使(shi)用，因而(er)(er)節省(sheng)了大(da)量金屬(shu)。
