石(shi)墨(mo)加(jia)熱(re)棒(bang)在真(zhen)空(kong)(kong)(kong)燒(shao)(shao)(shao)結爐(lu)中的(de)(de)(de)優勢 真(zhen)空(kong)(kong)(kong)燒(shao)(shao)(shao)結爐(lu)的(de)(de)(de)石(shi)墨(mo)棒(bang)加(jia)熱(re)元件(jian)(jian)(jian):石(shi)墨(mo)膨(peng)脹小、熱(re)沖(chong)擊性強,在一(yi)定溫度(du)范圍內,燒(shao)(shao)(shao)結爐(lu)的(de)(de)(de)溫度(du)愈高,機械性能愈好(hao)。加(jia)工(gong)性良好(hao),價格低(di)廉,給點髙(3700P),在燒(shao)(shao)(shao)結爐(lu)真(zhen)空(kong)(kong)(kong)條件(jian)(jian)(jian)下具(ju)有高升華點和(he)低(di)蒸氣(qi)壓(ya),在相同(tong)溫度(du)下能夠輻射(she)(she)比其它材料(liao)更(geng)(geng)多的(de)(de)(de)能量,例如比鑰熱(re)輻射(she)(she)強。 同(tong)時(shi)石(shi)墨(mo)又是很好(hao)的(de)(de)(de)脫氧理,石(shi)墨(mo)與金屬氧化物作用(yong)生(sheng)成一(yi)氧化碳(tan),一(yi)氧化碳(tan)不(bu)斷被泵抽走,對(dui)真(zhen)空(kong)(kong)(kong)是起凈化作用(yong),但石(shi)墨(mo)消(xiao)耗很大,壽(shou)命只有1萬(wan)小時(shi)。真(zhen)空(kong)(kong)(kong)燒(shao)(shao)(shao)結爐(lu)的(de)(de)(de)石(shi)墨(mo)加(jia)熱(re)元件(jian)(jian)(jian)不(bu)會對(dui)零件(jian)(jian)(jian)產生(sheng)滲碳(tan)的(de)(de)(de)不(bu)利(li)影響。 真(zhen)空(kong)(kong)(kong)燒(shao)(shao)(shao)結爐(lu)維修(xiu)方便,石(shi)墨(mo)棒(bang)加(jia)熱(re)元件(jian)(jian)(jian)可單件(jian)(jian)(jian)從燒(shao)(shao)(shao)結爐(lu)爐(lu)室直接更(geng)(geng)換,整體加(jia)熱(re)室可用(yong)托架移出(chu)燒(shao)(shao)(shao)結爐(lu)真(zhen)空(kong)(kong)(kong)室外,進行修(xiu)理。 真(zhen)空(kong)(kong)(kong)燒(shao)(shao)(shao)結爐(lu)爐(lu)子工(gong)作原理:用(yong)受控的(de)(de)(de)交(jiao)流低(di)壓(ya)大電流加(jia)在三相加(jia)熱(re)的(de)(de)(de)12根石(shi)墨(mo)棒(bang)加(jia)熱(re)元件(jian)(jian)(jian)上,以(yi)石(shi)墨(mo)產生(sheng)的(de)(de)(de)熱(re)量。
